The Proceedings, begun in 1878, are intended primarily as a medium for the publication of original papers, based on the collections of the National Museum, that set forth newly acquired facts in biology, anthropology, and geology, with descriptions of new forms and revi- sions of limited groups. Copies of each paper, in pamphlet form, are distributed as published to libraries and scientific organizations and to specialists and others interested in the different subjects. The dates at which these separate papers are published are recorded in the tables of contents of each of the volumes. The present volume is the hundred and second of this series. The Bulletin, the first of which was issued in 1875, consists of a series of separate publications comprising monographs of large zoo- logical groups and other general systematic treatises (occasionally in several volumes), faunal works, reports of expeditions, catalogs of type specimens, special collections, and other material of similar nature. The majority of the volumes are octavo in size, but a quarto size has been adopted when large plates were regarded as indispensa- ble. In the Bulletin series appear volumes under the heading Contri- butions from the United States National Herbarium, in octavo form, published by the National Museum since 1902, which contain papers relating to the botanical collections of the Museum.

NATIONAL MUSEUM Vol. 102 Washington: 1952 No. 3291 CONTRIBUTIONS TO THE MORPHOLOGY AND TAXONOMY OF THE BRANCHIOPODA NOTOSTRACA, WITH SPECIAL REFERENCE TO THE NORTH AMERICAN SPECIES By Foitxr LInvER INTRODUCTION Since the days when Packard’s “Monograph of the Phyllopod Crustacea of North America’ was published (1883), the accessible material of notostracans has grown considerably, and the principles commonly used for the taxonomy have been discussed in several papers. Analyses of these characters, especially by Braem (1893), Gurney (1923, 1924), Sidorov (1927), Barnard (1929), and Gauthier (1934), have established a considerable variation in most of the char- acters of European, Asiatic, and African forms. This variation, of course, does not make a survey of the Notostraca of North America an easy task, and when I venture such a survey here, I wish to note that in some respects it is tentative only. It is based mainly upon a study of the collections of the U.S. National Museum, amounting te 109 lots and considerably more than 2,000 specimens. ‘This study was performed during a 3 months’ visit to the Museum in 1946, and was made possible by a grant from the Smithsonian Institution, to which my thanks are due for this generous support. I am also greatly indebted to Dr. Waldo L. Schmitt and other officials of the Museum for having most kindly facilitated my work. Also, Prof. J. E. Lynch, University of Washington, Seattle, kindly allowed me to examine some important material from the northwestern United States. For comparison I had specimens from other parts of the world, though this material, about 3,000 specimens from 71 localities, has not been as comprehensive as could be desired. 1 APR6 1956 2, PROCEEDINGS OF THE NATIONAL MUSEUM VoL. 102 Gurney (1924, p. 559) says about the taxonomy of the Notostraca, “The separation of species within the genera Apus and Lepidurus is a matter of quite unusual difficulty, since there is much variation, and, as a rule, the only characters on which separation can be based are smal! and ill-defined.”” Barnard (1929, p. 230) agrees with him, and so do I. As for other phyllopods, the females of the Anostraca present a similar difficulty, as, sometimes, if they occur without males, it is not even possible to say with certainty to what family they belong. But the males of this order give excellent specific characters in the genital organs and the second antennae—organs which display a striking uniformity in the Notostraca. In the Conchostraca, the structure of the head and the carapace provides rather good spe- cific characters, but in these respects, too, the Notostraca are fairly consistent. The characters actually employed—helpfully reviewed by Barnard (1929, pp. 230-234)—for the most part represent differences of degree only. A striking example of this is Packard’s (1883, p. 319) key to the American species of Apus; a study of the type specimens of the species involved immediately reveals that the number of spines on the supra-anal plate, which seems to be the fixed point in this key, is not constant but overlaps the boundaries between his species. According to my experience, one seldom finds a specimen which is in complete accordance with the description of any of these species, and similar difficulties are met even when one goes to the type speci- mens. These are not numerous enough to cover the range of indi- vidual variation, nor are their descriptions extensive enough. Yet such variation is especially important when the characters involve differences of degree. . Of course, one can often compare material from neighboring locali- ties in order to learn something of this variation, or, better still, one can try to get abundant material from the original locality. The first course is generally the only one practicable in museum work, and I have tried it here. It is not very satisfactory, though some results seem to be obtainable in this way. Each sample of Notostraca ought to contain about 50 or more spec- imens in order to cover most of the variation. And, in my opinion, a new species should never be described from less than 100 specimens from the same district, preferably taken at varying times of the season. Paratypes are, In many respects, just as important as holotypes. A special question arises when we try to interpret the variation. Ghighi (1924) suggests that the variation may sometimes be due to the presence of two species in the same pool. I think that this occurs NORTH AMERICAN NOTOSTRACA—LINDER 3 only rarely, as in the Anostraca and in the Conchostraca, and if it should happen to occur in a particular sample, the fact would prob- ably be readily revealed when all characters are considered. I have not found any indications of mixed populations in this sense in the samples I have examined, nor can I find any definite reference to it in the literature, with the exception that Lundblad (1920) noted that species of different genera sometimes have been found in the same pool. In these cases no intermediate forms are reported. So far, I have considered only specific characters. Sidorov (1927) and Gauthier (1934) are convinced that there are geographical sub- species within Apus cancriformis of the Old World. I do not deny the possibility that there may be such taxonomic units in some North American species, most likely among the forms of Apus. Among the anostracans, which have similar habits, I have found some indications of geographical subspeciation in forms of the genera Branchipus and Tanymastiz of the Old World. Smirnov (1931) seems to be of similar opinion with regard to some conchostracans. However, I do not find it possible to separate geographical units out of the material to which I have had access. In my opinion the appropriate way of doing this would be to investigate thoroughly some limited areas, and to follow this with a comparison of samples from interspersed districts. ‘The possible existence of clines (Huxley, 1942, and Margalef, 1948) might also be traced in this way. During my work it appeared that a species from Asia and Europe, Lepidurus macrurus, is a synonym of the American species L. couesit. Further, I found that South American forms of Apus are the same species as the North American Apus longicaudatus. This may be significant. It is worth noting that no one since the days of Packard (1883) and Simon (1886) has tried to compare species from all over the world, and, with our present knowledge of the great latitude in variation of many characters, it does not seem at all improbable that additional species from different continents will be found synonymous. The present tendency to reduce the number of species in the Notostraca (see Gurney, 1924, and Barnard, 1929) is, I think, sound, and is well supported by our present knowledge of variation. This paper follows the same line. In the following pages I have tried to analyze, with the help of material from all continents, the commonly used taxonomic charac- ters and, also, a character which has been very much neglected, the number of body-rings of different kinds. This character has proved quite useful. One of the results is a new grouping of the species of Lepidurus into what seems to be two natural groups; another, that lower taxonomic units begin to be revealed among parthenogenetic 4 PROCEEDINGS OF THE NATIONAL. MUSEUM VOL. 102 populations, although the real status of these cannot be determined from the accessible material. In connection with this analysis I have also considered polypody, and the peculiar phenomenon I have called spiral growth, both of which are problems of interest from a more strictly morphological point of view. Finally, I have applied to the North American material the results of this analysis of taxo- nomic characters. TERMINOLOGY AND MEASUREMENTS Instead of the term ‘‘segment,”’ in referring to the postmaxillary part of the animal, I prefer the term ‘“‘body-ring.”’ The first 11 body-rings I call the thorax. This is followed by the abdomen, which is com- prised of leg-bearing body-rings, legless body-rings, and the telson, which is not a true segment, and which should not be included in the number of body-rings. The series of legs does not always stop under- neath a boundary between two body-rings; it may stop at any place quite independent of these boundaries (fig. 20). I have found it advisable to count half leg-bearing body-rings in those cases where the series stops approximately underneath the center of a ring, and a whole leg-bearing ring when the series covers almost the whole ring, disregarding those cases where the series only slightly surpasses a boundary. Incomplete rings (fig. 16) are often found at the anterior boundary of the telson, but very rarely within the series of rings. It is useful to have a short formula when describing the numbers of the various kinds of body-rings in a specimen or in a species. In this paper, I have used such an arrangement. Thus, the formula 11-+12+5—28 body-rings indicates that there are 11 thoracic, 12 abdominal leg-bearing, and 5 abdominal legless rings, forming a total number of 28 rings (telson not included). For a species the formula is more complicated because there is a considerable variation of these numbers within the limits of a species (Linder, 1947). If the abdominal leg-bearing rings number from 16 to 18.5, the legless rings from 5 to 10, and the total from 35 to 38 rings, the formula would be, 11+ (16-18.5) + (5-10) =35-38 body-rings.. Hf there is an incomplete ring, the abbreviation “i” is inserted, as in this example: 11--12+ 5+i=28-+i body-rings. It is also possible to indicate the presence of the interesting abnormality, spiral growth, and its place within the series. If a spiral of 3 rounds appears after the 25th body-ring, immediately followed by the telson, in a specimen with 12 abdominal leg-bearing rings, the formula would run as follows: 11+12+ 2+sp.3r.=25-+sp.3r. The telson bears a rather neglected structure, viz, a pair of dorsal sensory setae (fig. 28), surrounded by short spines, and a pair of caudal filaments. Between the latter there is, in the genus Lepidurus, the NORTH AMERICAN NOTOSTRACA—LINDER 5 supra-anal plate. I measure the length of this plate from the most anterior point of the basis of the caudal filaments to its apex. As Barnard (1929) and S@mme (1934) have pointed out, the total length of an animal cannot be measured with proper accuracy in pre- served material. The reason is simple enough. Anteriorly and pos- teriorly, the integument of a ring is much softer than in the central part. This soft integument may form a fold directed inward and for- ward, and in such eases the rings appear short and the total length of the animal is relatively short, too. But other specimens from the same lot, which have a carapace of similar length, may show no deep fold in these places, the soft integument being more or less stretched out between the more highly chitinized parts of the rings (fig. 1).

Highly chitinized parts of the integument indi- cated by heavy lines. a, Contracted; b, extended. the latter case, of course, the rings appear longer and the total length of the animal may be considerably greater than in the former cases. Tt is quite usual to meet with both extremes and a more or less con- tinuous series of intermediate cases in a lot containing a large number of specimens, as they may have been fixed in varying stages of con- traction. Rosenberg (1947) noticed a considerable shrinking of the specimens when they were placed in preservation fluid. It is also obvious that preservation, after an indeterminable time, weakens the soft tissue in and between the body-rings and thus causes a length- ening of the body to a variable degree. In very old material macera- tion (and lengthening) may have gone rather far. It is, however, desirable to give an idea of the length even if it cannot be accurately stated. I measure the length on the midline from the apex of the head to the base of the caudal filaments. Thus, in Lepidurus, the length of the supra-anal plate is not included in the figure of the total length. This may seem a little odd, but in this way comparable figures for Lepidurus and Apus are obtained. The length of the supra- anal plate in the former genus may be up to 44 percent of the length of the carapace, and thus it would be quite misleading to include this plate, which has no counterpart within the genus Apus. 6 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 Barnard (1929) also points out that we cannot give an accurate count of the body-rings exposed behind the carapace. In order to give some, even if not an accurate, idea of this conspicuous feature I have mentioned the number in some specimens. But I give this number, as well as the figures of the total length, only with a stated reservation as to its accuracy. As Sémme (1934) has shown for Lepidurus arcticus, the carapace is little affected by the preservation fluid and thus can give an idea of the size of the animal. This is only natural, because it is contin- uously and highly chitinized. Foilowing the general custom, I measure its length along the mid-dorsal line. Of course, we cannot be sure that variations in this figure closely follow the variations of the real total length of the body; the relation may vary according to varying ages of the specimens, to say nothing of the varying contrac- tion. To obtain the greatest width of the carapace, the usual method seems to have been to measure it in a straight line. This is not reasonably accurate, because the height of the carapace may vary, sometimes to a considerable degree. It is better to measure the greatest width from the carina to both sides (fig. 2). In cases of Ficure 2.—Cross section of the carapace of a notostracan, showing how the width of the carapace is measured. distortion, I have flattened the carapace to a shape similar to normal appearance before taking the measurement. I count 5 endites on each leg (fig. 26). The coxal lobe is the first endite; it is essentially similar to the other endites in the arrangement of the setae and has on its margin similar small elevations covered with small needlelike structures. What Packard (1883) calls the sixth endite is quite dissimilar to the more basal, real endites; it has only a single row of setae and spines along its margin, and no trace of the small elevations mentioned above; I call it the endopodite, as many other authors do. Packard’s ‘“flabellum” is the exopodite, and his “gill” is called epipodite in this paper. Further, we some- times find what may be the vestige of a preepipodite (fig. 22) in the form of a small elevation with a few setae (cf. Eriksson, 1934, p. 236). Specimens from the following museums were examined: Muséum National d’Histoire Naturelle, Paris (Paris Mus.). Naturhistoriska Riksmuseet, Stockholm (Stockholm Mus.). Zoologiska Museet, Kungl. Universitetet, Uppsala (Uppsala Mus.). United States National Museum, Washington (U.S.N.M.). NORTH AMERICAN NOTOSTRACA—-LINDER 7 BODY-RINGS AND POLYPODY Following the usual custom, I consider the body proper to begin with the first postmaxillary ring, which is, however, strictly separated from the head only on the ventral side. Packard (1883) counts the first ten body-rings as the thorax, and the following ones as the ab- domen. I include the eleventh body-ring in the thorax, as does Simon (1886) in his important revision of the phyllopods and as Sars does in his many descriptions of various notostracans. More than a hundred years ago Zaddach (1841) showed, in an admirable work now almost neglected, that the first 11 body-rings are essentially similar to each other in the equipment of muscles, while the following ones differ quite considerably from them. Further, the legs of this portion are different, though the boundary in this respect is usually not distinct. A boundary between different regions in this location is recognized in crustaceans of many orders—so many, in fact, that it is not likely to be a mere coincidence (Linder, 1941, p. 113). I have abandoned the use of the term ‘‘segment,’’ replacing it with the term “body-ring,” when real rings or parts of rings are concerned. I do this for the reason that in the abdomen there are no complete, ordinary segments but two series of parts of segments, in some respects independent of each other—the series of rings and the series of legs. These are united to form a composite structure unique in appearance. This is the true meaning of the much discussed phenomenon, poly- pody. Itis not an absolutely new view. Lankester (1904) expressed a similar view, but did not give evidence for his opinion. However, Zaddach (1841) had already supplied much evidence supporting that opinion, and the following facts, most of which have not been noticed by earlier authors, may give additional evidence: 1. The series of legs covers a varying number of body-rings in specimens from one locality. Zaddach (1841) has given an example of this. He also regards the number of pairs of legs as fixed; however, I have found that this number is subject to a considerable variation. The series of legs may stop at any place under a body-ring (fig. 20). If we choose a certain pair of legs in the caudal part of the series of legs, and determine its place under the series of body-rings, we shall find that it has varying positions in various specimens from the same locality (see table 2, p. 42). Thus, each body-ring in the abdomen does not have a fixed number of pairs of legs, and this means that there is no evident correlation, as is supposed by most authors, between the series of legs and the series of abdominal body-rings. Evidence for this fact from extra-American material is given in an earlier paper (Linder, 1947). 2. The boundaries between the body-rings in the leg-bearing part of the abdomen do not continue ventrally. They stop at a longitudi- 8 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 nal boundary, always well marked and often formed as a ridge in the integument (fig. 20), which delimits the leg-bearing area. This area may be divided into “‘segments” coinciding with the legs but totally independent of the boundaries between the body-rings. Zaddach (1841) has already described the ventral “segmentation” and the corresponding division of the longitudinal muscles in this area in Apus cancriformis. 3. In two cases of abnormal growth of the body-rings that I have found, the series of legs is not affected by the abnormal turns, or spiral growth, of the related body-rings (fig. 17). The first two points hold good for each of the species of Notostraca that I have examined, though some of the details may be difficult to observe in specimens which have just molted or are badly preserved. It is a well-known fact that the rate of production of new body-rings (in early postembryonic stages) is quite different from that of the legs, with their muscles and nerve-cord ganglions. From the caudal end of the series of legs there are produced, at an almost frantic rate and in considerable number, the elements of the leg-bearing area, but the body-rings, budding from the anterior margin of the telson, increase in number relatively slowly. The body-rings do not vary much in size, but the elements of the leg-bearing area grow smaller and smaller caudally, as if the animal meets the frantic activity of this part with something like starvation of its individual elements. We might assume a kind of organizer at the end of the series of legs (for what else could we assume?) that is, in some way or other, less favored than the ordinary organizers at the anterior boundary of the telson. I have noticed in many specimens that this disproportionate development has continued during the further growth of the animal. Thus, we often notice that in a larger animal the series of legs covers a smaller number of body-rings than is the case in a smaller animal in the same lot (see table 2), indicating that the size of the body-rings, but not necessarily their number, increases faster than does the series of legs. Other facts also point to this conclusion: an oblique striation occurring at the area where the body-rings and the series of legs meet, explained as the mark of a tension between the two parts as they grow at dissimilar rates; and the moving forward of the fiftieth pair of legs, as observed in table 2 (we note that this moving forward does not exactly follow the changes in size, but individual variation in these complicated processes is to be expected). NUMBER OF BODY-RINGS It seems to be the rule that neither the total number of rings nor the number of abdominal leg-bearing rings is given in descriptions NORTH AMERICAN NOTOSTRACA—LINDER 9 of North American Notostraca. There are few exceptions to this rule. Packard (1883) mentions the figures for one specimen of Apus lucasa- nus and Rosenberg (1947) quotes fixed figures characteristic of his species A. oryzaphagus and A. biggsi. The number of legless rings, on the other hand, is almost always recorded, and a slight variation in this respect is often noticed. Interesting information about Lepidurus arcticus is given, though only with some hesitation, by Chamberlin and Duncan (1924, p. 99): ‘““The number of segments visible on the dorsal surface from the point of attachment of the carapace to the body seems to be either 26 or 27... . Behind the appendage bearing segments are five others, exclusive of the telson, which are without appendages of any sort.’’ As the above-mentioned point of attachment stretches over the first body-ring, we may con- clude that these authors found the number of body-rings to be 11+ (11-12) +5=27-28 (telson not counted). Even in descriptions of species from other parts of the world we seldom get information about the number of leg-bearing abdominal rings; at times a fixed total number is given, together with the number of legless rings, but without any attention to a possible variation of the former figure. Zaddach (1841) provides an exception; he says that in A. cancriformis the number of leg-bearing abdominal rings (in “pars abdominis posterior,’ according to Zaddach) is 17 or 18, the number of legless rings 5 or 6, and the total number of body rings always 34. All authors except Chamberlin and Duncan seem to take it for granted that the species of Notostraca are nomomeristic, but this is not true of any of the species examined by me. From figures 14 and 31 it can be seen that a variation in number is found not only in the legless rings, but in the leg-bearing ones, too. These varying numbers, together with the 11 thoracic rings, are combined in different ways to give a total number varying within the limits of a species. This is true of every species of which I have seen a reasonable number of specimens. When I now proceed to analyze what I have found concerning the variation of these figures—a preliminary analysis in some respects because the material is rather scanty—I shall begin, not in the tradi- tional way, with a treatment of the legless rings, but with the total number of rings and the number of abdominal leg-bearing rings. These are the primary characters. The number of legless rings is not a simple character; it is the result of the varying interplay of the two other series. As for the total number of body-rings, the range of variation may be quite considerable in specimens from the same locality. In a new species of Lepidurus from Grand Coulee, Wash. (see p. 39), the males 10 PROCEEDINGS OF THE NATIONAL MUSEUM VoL. 102 have 30-33+1 and the females 30+i-34 rings (fig. 14). The range is also great in A. longicaudatus from Wyoming (U.S.N.M. No. 58766), where the males have 41-44 and the females 39-++i-43 rings (fig. 31). These are relatively extensive samples, the former containing 54 males and 42 females, the latter 33 males and 98 females. In smaller samples the range of variation is not so great. The extremely high and low numbers of rings in one sample are usually represented by rather few specimens. No doubt the average number differs in various samples of the same species. But we cannot reasonably compare samples with 1, 2, or 10 specimens with samples containing a hundred or more specimens. Small samples give very uncertain figures, and museum work, in this respect, is much hampered by the fact that the great majority of samples contain a very small number of specimens. Statistical calculations, however desirable, are thus rendered very difficult. There seems to be a general rule that species with a large number of rings have a greater range of variation than species with few rings, both in Lepidurus and in Apus. There are some exceptions to this rule, but not many, in the material I have seen. The fewest rings in Apus occur in forms that have a clear parthenogenetic tendency and that show a very small range of variation. About these more will be said later on (see p. 12). Similar forms belonging to a group with relatively few body-rings are found among species of Lepidurus. Body-rings in the species of Lepidurus range from 25 to 34, those of Apus from 30 to 44. In the former genus, the high numbers of 30-34 are represented by two species only, L. bilobatus and a new species described in this paper, both of which differ from the other species of the genus in the number of leg-bearing abdominal rings, and, most evidently, in the number of legs. Apart from this grouping, and from what has been mentioned about parthenogenetic forms, I cannot find clear correlations between the number of rings and other characters. I doubt the validity of Rosenberg’s (1947) method of distinguishing taxo- nomic units—and not lesser units at that, but species—by associating a certain number of rings with a certain size of specimen, because I think that further research is necessary to establish the conditions of the variation in size, which in some lots is considerable, in others rather small. It is usual for the males to have a higher total number of rings than the females of the same species, though the rule has many exceptions. It is, of course, necessary to know whether the number of rings is really fixed in adult specimens—non-adult stages are not considered here—or whether it increases with an increase in size of the specimen. I have attacked this problem, which has never before been investi- gated, in two ways: first by comparing the number of rings in small NORTH AMERICAN NOTOSTRACA—LINDER ll and large specimens in the same sample, and second, by comparing the old and the new integument of specimens in molting. All my ob- servations agree that there is no general rule that larger specimens have a higher total number of rings than smaller ones. On the contrary, I have not infrequently found relatively small specimens with a high number (see fig. 14). Also, I have thoroughly examined about a hundred molting specimens of various species, and in none of them have I found a new ring appearing from the telson in the underlying, new integument. Judging from this, I think I am entitled to assume a fixed total number of rings in an adult specimen. As for the variation in the number of leg-bearing rings, I have found no clear rule when comparing larger and smaller specimens from the same lot. When examining molting specimens, however, I have found two cases where the number of pairs of legs is mcereased by one in the underlying, new integument. Thus we must reckon with the possibility of an increase in the number of legs, and, conse- quently, even a slight increase in the number of abdominal leg-bearing rings, with an increase in the size of the animal. However, I think we can be sure that this increase, if present, will not be great. The usual range in the number of leg-bearing abdominal rings in the genus Lepidurus is 9.5-13. This applies to all extra-American species I have examined (L. apus, L. kirkii, L. viridis), and to most American species (L. arcticus, L. packardi, L. couesii). This condi- tion, together with the similarly small number of legless rings, at least in some cases helps to explain the short abdomen commonly men- tioned as a character separating Lepidurus from Apus. Packard (1883), however, mentions that L. bilobatus has an unusually long abdomen, with many body-rings exposed behind the carapace; and I found, when examining a specimen of this species marked ‘‘type’’ in the U. S. National Museum, that it has 16.5 leg-bearing abdominal rings. Further, in material consisting of more than a hundred speci- mens of a new species from the State of Washington, I found this number to be 14.5—-18, while 12 specimens of a variety of this species had 16-17.5. Corresponding to the high number of leg-bearing abdominal rings we have a higher total number of body-rings here than in other species of the genus; there are more legs, and, generally, more rings exposed behind the carapace. In my opinion, these figures indicate that there are two groups of species within the genus Lepidurus, whatever the taxonomic category we choose for them. In the American forms of Apus, the number of leg-bearing abdom- inal rings ranges between 16 and 21 (males 16-18.5, females 17.5-21). In one large lot I have seen every number in this range represented (see fig. 31). Usually, the females have more, sometimes many more, leg-bearing abdominal rings than the males of the same species. 12 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 The variation in the number of legless rings is often used as a taxonomic character. This appears to be a useful character in South African forms of Apus (Barnard, 1929), but in the North American forms I have not found it to be of much aid in separating species. In Lepidurus, the number varies within narrow limits (4—5.5 in the great majority of forms), with no specific differences corresponding to the differences in number; a few specimens having 3, 3.5, or 6 legless rings show no other essential differences. There is, of course, the possibility that Z. packardi may have a high number and that this character may be of taxonomic importance, the type specimen having 6 legless rings. But I do not think this is probable. In two lots (5 specimens) that I consider belonging to this species I found 4.5-6 legless rings. In Apus, the whole range in the American specimens I have seen ig 4.5+1-13 in the females and 8-15-++-i in the males. It seems that this range of variation ought to be great enough to include several species (or subspecies, or forms) with varying ranges, and I will cer- tainly not deny the possibility that lower taxonomic units than species may be separated. However, I have seen a single lot of Apus that covered much of this range (9+1-13 in the females and 12.5-15+1 in the males, as shown in table 6). This is an extreme example, the range of variation being smaller in other samples, especially in those with only a few specimens, As arule, the males have more legless rings than the females of the same species because they usually have fewer leg-bearing rings but a higher total number of rings. BODY-RINGS IN PARTHENOGENETIC POPULATIONS It seems rather remarkable that an author like Zaddach (1841), extremely careful in so many details, gives a fixed number of 34 body-rings in Apus caneriformis. And Rosenberg (1947) definitely states that all specimens, several hundred in number, of his species A. oryzaphagus have 35 body-rings (36 including the telson, according to him). J have seen 6 of them (U.S.N.M. No. 88360) and found 5 to have 35 and 1 to have 34+1 body-rings. Rosenberg describes another form, under the name of A. biggsi, where all specimens have 36 rings (37 including the telson), but here it seems uncertain whether he had enough specimens for comparison. I found 3 of them having 36 and 1 having 35++i rings (U.S.N.M. No. 88361). In these cases the statements of a fixed number may result from the counting of incomplete rings as ordinary rings. Even so, the range of variation is very small. =| “N Bqos0IO MW WIoIp 2288nN09 “7 EPI “ON Unes “NYY WpOYxooyg = “BLTEqIg & | 801) O01xZ | 96r! 9 LE |9% |G 8t) 06 | Z| I+S 4% | SOL} t+9z| © | ‘N ‘foysxesy wory wsano °7 weiss beads |Ferk ad) o kee £ leek oe 19¢ “ON wanes “Nyy wpoyyoyg “Bldaqig 8@ | LIT § OX SI L IZ ¢ 8I | oz td g IE |-22 O | ‘'N ‘BUI[NOXIN WodJ g2san09 “7 38 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 European part of the U.S. S.

Remarks.—Outside America, there is a species with a similar telson and supra-anal plate, LZ. macrurus Lilljeborg. The general resem- blance between this species and L. couesi was noted by Lilljeborg, who mentioned (1877, p. 14) one difference only, that the former has 6 to 8 rings exposed behind the carapace and the latter only 5. This character ‘is generally recognized to be somewhat unreliable” (Gur- ney, 1923, p. 502) because of the varying state of contraction of the specimens (p. 5), and I have seen American specimens of L. couesit with 7 exposed rings as well as specimens of LZ. macrurus, identified by Lilljeborg, with five exposed rings. I have examined 25 Asiatic specimens identified as LZ. macrurus by Lilljeborg. They, as well as some specimens from a more southern locality, agree perfectly well with the American specimens of L. couesit as described, and ought to bear the same name, which is 2 years older than that given by Lilljeborg. The relationship of this species to the European L. apus, to which it bears a certain resemblance, is in need of clarification, but I have not had enough material of the latter species to make a detailed comparison. LEPIDURUS BILOBATUS Packard Figure 13; Puars 2 (Ficurss 3, 4) Lepidurus bilobatus PackKarp, 1883, p. 318. Description—A supplementary description of a female labeled “Type, Utah, coll. Henshaw” (U.S.N.M. No. 11606) is given here. Body-rings 11+16.5+4.5=32. Legless rings with many (19) densely crowded spines on the ventral side, dorsally 7 spines. Supra-anal plate slightly bilobed, with 8 dorsal spines, 4 of which are smaller than the others, all of them placed on a slightly marked keel. Nuchal organ oval, placed between hind parts of eye-tubercles. About 62 pairs of legs. In other respects there is reasonable agreement with Packard’s description. Further particulars are given in table 1 (p. 36). Remarices —The real status of this type seems to be a little uncertain, because Packard’s type locality was not Utah, but Po Cafion, Ver- million River, Colo. However, the specimen most probably comes from Packard’s collection, and I feel reasonably certain that it belongs to this species. The large number of abdominal rings agrees well with Packard’s statements that “the abdomen is longer than usual’’ and “‘there are about sixteen segments beyond the posterior edge of the carapace.’”’ Another species with many abdominal rings is de- scribed later on in this paper (p. 39), but LZ. bilobatus is easily dis- tinguished by the position of the nuchal organ, the typical arrange- ment of the spines on the posterior emargination of the carapace, and NORTH AMERICAN NOTOSTRACA—LINDER 39 by the varying sizes of the spines on the supra-anal plate. In the two last mentioned respects, there is good agreement with Packard’s description. ‘Seven more or less well-marked median spines” on the telson, according to Packard, stands in sufficiently good accordance with the condition in this specimen. Bilobation of the supra-anal plate occurs here, in agreement with Packard’s description, but it is to be remembered that this character is not an important one. Tentatively, I have placed here another specimen (U.S.N.M. No. 82028) which bears only the label ‘“‘ Probably Arizona.”’ In a case like this, when there is a little uncertainty about the status of the single existing type specimen, and the original description is not very good, it may be questionable whether we ought to discard the species or keep it on record. In my opinion, the description is good enough to enable us to identify the species with reasonable accuracy. However, it seems desirable to search for more material from the type locality or its vicinity.

NORTH AMERICAN NOTOSTRACA—LINDER 49 Remarks.—This new species is especially interesting, because it belongs (see table 3) with Z. bilobatus in the group with many abdom- inal rings. The variation of the species, as limited above, may perhaps seem to be rather great. It includes forms with a very spiny carapace together with forms where the carapace is quite smooth; but intermediate forms occur in great numbers, and we find a similar variation in several species of the genus Apus (Barnard, 1929). Furthermore, the form of the supra-anal plate is highly variable; but, as I have shown previously (p. 26), this is true of many species. The great range of variation must be seen in connection with the fact that the species is described from such a great number of specimens from the same district. The species is easily distinguished from L. bilobatus by the size and place of the nuchal organ and the eyes, characters to which I must ascribe great taxonomic importance. Its relation to the following form, however, I cannot regard as quite clear.

All characters lie within the range of variation mentioned for this form, except for some details of the carapace. On the middle and caudal part of its lateral margin there are numerous stout spines considerably larger than those in the principal form, though not so large as the spines at the posterior emargination. All the first-mentioned spines are directed straight outward. This is a very conspicuous feature and the explanation of the name echinatus. Furthermore, the carapace is more rounded and a little larger in relation to the body than in the typical form, and its posterior emargination is less deep, leaving a smaller number (7-10) of rings exposed behind the carapace. Remarks.—It is regrettable that there are not more than 12 speci- mens of this variety, because this small lot cannot be expected to show much of the variation. As a provisional measure I have given it the rank of a variety within Z. lynchi, because it shows a great similarity to this species in such important respects as the number of abdominal rings, the characteristic appearance of the eyes and the nuchal organ, and the array of spines on the lateral margins of the carapace. At the same time, there are clear differences between the two forms in the shape of the carapace. There is a certain similarity between this variety and L. lemmoni Holmes, especially in the array of lateral spines on the carapace and, perhaps, also in the position of the nuchal organ. But, as I will discuss in more detail later (p. 51), the similarities are more or less uncertain, and I consider L. lemmoni as an insufficiently known species. There are dissimilarities, in any event, among which the different shape of the posterior emargination of the carapace is the first to attract attention. I consider it better in this case to estab- lish a new variety than to venture a highly dubious identification with an insufficiently described species. LEPIDURUS LEMMONI Holmes Lepidurus lemmont Houmss, 1894, p. 585 (not Coopey, 1946, p. 338). Description.—The principal points of the description of this insuffi- ciently known species follow: About 4 body-rings exposed behind carapace, 4 or less legless body-rings (the author says 5 instead of 4, but in all probability he counts the telson as a ring). Number of spines on last body-ring never far from 12. Supra-anal plate rather long and may be rounded, truncated (obliquely so in some specimens), or, in some cases, bilobed, with 2-3 spines in midline, but no median carina except where the spines are situated. Carapace oval, carina with 10-15 teeth, posterior emargination with 5-7 teeth, sides with numerous small teeth. Nuchal organ round, small, considerably elevated, and located considerably behind the posterior margin of eyes. Length, 28 mm. NORTH AMERICAN NOTOSTRACA—LINDER 51 Type locality.—Honey Lake, Calif. Types.—The type specimens (4 9, 1c”) are said to have been lost in the San Francisco fire. Remarks.—Holmes’ description is very good for its time, but naturally it does not mention the number of abdominal leg-bearing rings or the total number of rings. In these respects, there are two well demarcated groups within the genus, and these totals seem to be essential for a proper identification. Perhaps both were low, because he reports only 4 rings exposed behind the carapace; but we cannot be certain of this. Equivalent totals in L. lynchi var. echinatus are high even though as few as 7 rings are exposed. Only 12 specimens are known of the latter form, and only 5 of LZ. lemmoni. So few speci- mens cannot be expected to show a full range of variation; thus, it is possible that LZ. lemmoni may fall in within the upper limits of variation in this respect. And we must not forget that, in general, the number of exposed rings is shown to be an unreliable character, so its value as an indicator of the number of rings is very uncertain. Other characters do not give clear indications, either. The nuchal organ is “‘located considerably behind the posterior margins of the eyes.” Perhaps we have a condition here similar to that in L. lynchi and L. lynchi var. echinatus, but a precise comparison is impossible because Holmes does not mention the place of the organ in relation to the eye-tubercles, only to the eyes. The very long caudal filaments present a character of doubtful significance. In each large lot of Lepidurus there is considerable variation in the length of these appendages. The lateral spines on the carapace look quite conspicuous on Holmes’ figure. Similar spines, or larger still, are found in L. lynchi var. echinatus, whereas in all other notostracans I have seen the correspond- ing structures are minute and inconspicuous. But echinatus differs clearly from ZL. lemmoni by its very shallow posterior emargination of the carapace as well as by the structure of its legs, and so an identification with this form seems highly improbable. To sum up, the characters given for L. lemmoni cannot be regarded as sufficient for a proper identification. In my opinion, we had better not keep the species on record. It can be abandoned without much trouble, because, as far as I can see, it has been recorded only once since its establishment, and in this case there is undoubtedly an error of identification. Coopey (1946) refers some specimens from Oregon to this species, though with the express reservation that they are only provisionally identified. Most kindly, be has given me the opportunity of examining 3 speci- mens from Rocky Point Pond, Klamath County. I find them to belong to L. couesii. The telson (without supra-anal plate) is short and broad, and on the conspicuous keel of the supra-anal plate there 52 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 is a large number of spines of varying sizes (2-3 spines in L. lemmoni). Even the place of the nuchal organ is as in L. couesw. All characters considered, the specimens are quite typical representatives of this species. Genus APUS Schaeffer Apus SCHAEFFER, 1756, p. 131.—GurNEy, 1923, p. 497.—Barnarp, 1929, p. 229.1 The principal characters of the genus are, in my opinion, the absence of a supra-anal plate on the telson (p. 26), the relatively large number of body-rings, 30-44 as against 25-34 in Lepidurus (p. 42), and the reduction of the second maxillae in full-grown speci- mens (p. 28). Even within these limits, however, the genus presents a unit that is not quite homogenous or well distinguished from the genus Lepi- durus, because one species, A. cancriformis, is in several respects sug- gestive of the latter genus. Absence of a supra-anal plate seems to be characteristic of all species except A. cancriformis, where we may find something rather similar to such a plate (fig. 8). It is very short, but we can only assume that it is essentially the same structure as the plate in Lepi- durus, so that A. cancriformis may be regarded as an intermediate stage, in this respect, between Lepidurus and the remaining species of Apus. In the reduction of the second maxillae, the same species forms an exception. I have found it to have, in full-grown specimens, just as well developed maxillae as in any species of Lepidurus. It has very few body-rings as compared with almost all the other species of the genus that I have examined. There are a minimum of 30, and, generally, a maximum of 34. In only one sample of A. cancriformis have I found more, 35 in a female and 35 or 37 in the males (U.S.N.M. No. 58211, from Nanking, China). I have observed a similarly small number of rings in A. sudanicus from South Africa, identified by Barnard (U.S.N.M. No. 75749). The male in this sample has 32, the two females 33 and 33+ body-rings. All the other species of Apus have a larger number of body-rings. A. longicaudatus comes nearest with 34-++i-44 rings (see table 4); however, I am fully aware that in many forms we know too little of the number to be able to make definite groupings of the species according to this character. Still, it may be considered significant that A. cancriformis, which comes close to Lepidurus in the structure of the telson and the second maxillae, also has a similar total number of body-rings. This is a further indication that the species is a sort of connecting link between the two genera. 1I fully agree with Gurney and Bamard that the name of Triops Schrank, 1803, pp. 180, 251 (sometimes spelled Triopes or Thriops), ought to be rejected. NORTH AMERICAN NOTOSTRACA—LINDER 53 In its general appearance, also, this species is suggestive of the genus Lepidurus. The body, because of its small number of rings, may be almost completely covered by the carapace, which sometimes leaves only part of the telson exposed. Such proportions are unusual in the species of Apus, and it is interesting to notice that they occur, not in the species of Lepidurus that have a similar number of rings (L. bilobatus, L. lynchi), but in those that have the fewest rings. The number of abdominal leg-bearing rings, a figure that proved helpful as a means of distinguishing groups within the genus Lepidurus (p. 31), gives no clear character in Apus. In the whole genus, it ranges from 12.5 to 20, figures that are generally higher than in Lepi- durus. Im A. cancriformis, the range is usually 16 to 18, though I have occasionally observed either fewer or more of such rings (the fewest was noticed, not in this species, but in A. sudanicus, as noted above, where a male has 12.5 and two females 13.5 and 14 such rings). The number of pairs of legs in various species is too little known to enable us to draw any conclusions about its taxonomic value. On the whole, we must admit that much work remains to be done before we will be able to make a reasonably good arrangement of the species of Apus.

As far as I can see, the various species of Apus described from the North American continent must be united into one species, A. longi- caudatus. A study of reasonably extensive material shows that the three species of Packard, enumerated above, cannot be properly de- marcated from each other and from A. longicaudatus, and the same applies to Rosenberg’s species. Packard’s material was probably too limited to enable him to detect the unbroken series of variation in most of the characters used by him. It was not so much that he had material from so few localities— 4 species from 13 localities—as that only a few specimens were avail- able from each locality. One of his species, A. newberryi, was based upon three females from two localities. 102 vol.

Pearse (1912) gives a good example. He had an unusually large number of specimens from one locality and found a remarkable variation in the number of dorsal spines on the telson, which Packard uses as one of the main characters: ‘The armature of the telson is somewhat variable; on the dorsal side there is commonly one median spine, but there are often two; there are usually two lateral spines at the proximal edge of the telson, but there are frequently more” (Pearse, 1912). Here is a mixture of characters from several species. A. lucasanus and A. longicaudatus are described with one median spine, A. aequalis with two, as is one of the specimens of A. newberryi mentioned by Packard. ‘Lateral spines at the proximal edge of the telson,” probably means the spines around the dorsal sensory setae, of which one on each side is described as large in A. lucasanus. Thus most of Pearse’s specimens ought to have agreed with A. lucasanus, but others not. Further, Pearse found the length of the carapace to be “about equal to the portion of the body exposed behind,” as in A. aequalis according to Packard; it was obviously on these grounds that he identified his specimens with this species and dismissed the similarities with other species (especially A. lucasanus), which were observed on the telson of most specimens. Mackin (1939) says that Packard’s three species are synonyms of LeConte’s species; his studies on material from Oklahoma and neighboring States showed that the characters used by Packard are of little value in taxonomics. However, he regards his conclusion as only tentative. Packard’s descriptions cover a lot of characters, but many of them are considered in only one species, so that comparisons in some re- spects are impossible. Those presented in table 5 are especially stressed by him. (In this table I have, in all cases, given one less ring than Packard, because he obviously counts the telson as a body ring, while I do not.) The length of carapace in relation to length of body, and the number of body-rings exposed behind the carapace, vary according to the contraction of the rings, a condition itself highly variable. These characters are, of course, also influenced by the number of body rings, though in a rather erratic way on account of the variable con- traction of the rings. These characters of Packard’s are not simple characters, and generally they are more or less unreliable. As for the number of legless rings, the examples in table 6 show how greatly this often varies in specimens from the same locality. The sample from Wyoming (columns a, c) is significant. It contains many more specimens than the others, and it covers the numbers given by Packard as characteristic of three species, A. newberryt 58 PROCEEDINGS OF THE NATIONAL MUSEUM VOL, 102 (10 in females), A. Jucasanus (10 in females), and A. longicaudatus (9 in females, 13 in males). More than that, it presents an unbroken series beginning with a number of legless rings not much greater than that given for A. aequalis and ending with a number (15+) considerably higher than those observed by Packard. No correlation with other characters has been found.

SNAIL HOST OF ORIENTAL LUNG FLUKE—ABBOTT 97 LIFE HISTORY HABITAT As has been stated earlier, the various subspecies or geographical races of Vhiara granifera have not been studied adequately, so that details of its geographical distribution cannot be presented at this time. However, the limits of its distribution as a whole are fairly well known. This species lives in fast-flowing fresh-water streams. Its most westerly limits include the Island of Ceylon and the eastern coast of India. Its range extends easterly to include the coasts of Siam and southern China, the East Indies, and the Philippine Islands. ‘To the north it is found on Formosa (Taiwan) Island and the small islands south of Japan. Farther east, it is common in Melanesia, especially the Solomon Island Archipelago, the Marianas, and the Polynesian islands of the Hawaiian and the Society Islands. Undoubtedly the topography and nature of the areas in which this species is found varies from place to place, but it is highly likely that certain optimum environmental conditions are common to all its localities. Thus we may find this species in streams very near the sea in certain small islands, but considerably inland and at higher altitudes on such large islands as Luzon, Leyte, and Mindanao in the Philippine Islands. In the isolated Micronesian islands of the Marianas only three islands are large enough to have permanent streams: Guam, Saipan, and Rota. All three support colonies of T'hiara (Plotiopsis) scabra, but only the first possesses streams large enough to maintain popula- tions of Thiara (Tarebia) granifera. Guam (Guajan) Island is 82 miles long by 4 to 10 miles wide and about 225 square miles in area. It is mountainous in the southern half, where a great number of small streams flow down to the sea. The northern half forms a low plateau, which is devoid of permanent streams. The majority of the streams in the southern half of Guam are col- onized by 7'hiara granifera. Collections were made at the localities listed. The number following each station record indicates the number of specimens collected (fig. 40). A. Zadue Maagos River. 1945. D. Frey collector. 92. B.

The snails are most abundant in the shallow riffles where the flow of water is fairly rapid and where the bottom consists of a pavement of small stones. Occasionally the snails may be found congregated on firm sandy bottom provided there is a healthy flow of water. Waters of the stream that are exposed to direct sunlight during most of the day appear to attract this species. The upper reaches of the streams that have a very rapid flow of water are not favorable, although other mollusks such as Veritina and Septaria may be abundantly represented. The tiny flows of headwater tributaries, which are less than a foot in width and 2 inches in depth, will not support 7’. granifera but are favorable to 7’. scabra. The stream at Umatac, in the southwest end of Guam, has the colony with the greatest number of largest individ- uals. The maximum concentration of snails (about 10 per square foot) is found in the fairly level section of the stream, which is about 30 feet wide and half a foot deep. This area is only a few hundred feet from the high-tide mark of the ocean but is probably never diluted with salt water except perhaps during typhoons, which may come from the west. Conditions at Agafia Spring, the most northerly located colony on the island, are interesting in the dwarfing effect on the size of the individuals. The spring is used as a source of water for nearby Agana and at present has a pumping station located there. The spring proper is about 30 feet deep, with a diameter of about 60 feet. The upsurge of water is moderate, but the overflow is relatively fast, con- sisting of a 100-foot sluiceway about 3 or 4 feet wide. There are abundant algal growths in the spring. The shells and animals of this colony are similar to those of other Guam populations except in the reduction in size. No environmental cause for this could be found. Even more pronounced dwarfing is evident in specimens that were introduced to the large spring at Lithia, Fla. On Leyte Island, Philippine Islands, where numerous collecting sta- tions were made, 7hiara granifera was found in large rivers and small streams. High in the central mountains, where large stream condi- tions duplicate those on Guam, colonies of this snail are rather com- mon. In the extensive Leyte Valley, at the northeast end of the island, the larger rivers, with silty to sandy bottoms, meander; only rarely is 7’. granifera found along the very edges of the rivers, where the flow of water is moderately fast. However, smaller streams, which pass down from the foothills bordering the valley, are excellent habitats. SNAIL HOST OF ORIENTAL LUNG FLUKE—ABBOTT 99 The water-temperature limits of this species were not appreciated until a survey was made of the Lithia Spring, Fla., populations. In aquaria and the spring, where the temperature remains around 76° F., the snails are able to maintain themselves in adequate numbers. How- ever, just beyond the influence of the warm waters of the spring, where the cooler waters of the local river are about 50° F. or less, the snails are absent. The overflow ditch outside the extensive plant aquaria in Tampa is colonized by these snails during the warm summer months, but in winter, when the water temperature is as low as 50° F., these snails die off. The temperature recordings for Guam streams and even for the rivers at 3,000 feet altitude on Leyte Island were all above 75° F. BIONOMICS GRrowTH AND sizE.—The rate of growth of the shell has not been de- termined, although, from common experience in raising these snails in aquaria, it is assumed that adult size or maturity is reached within 6 to 12 months. Two preliminary studies were made of the character of shell size, one on the 13 colonies collected on Guam Island, the other on the populations of Lithia Spring. In the latter study, dissections were made to determine the size at which individuals become sexually mature, for there is no tell-tale flaring or thickening to the outer lip that often accompanies maturity in many other molluscan species. The significant differences in the size of samples taken at various places in the spring, only a few dozen yards from each other, are extremely important in demonstrating the wide range in size exhibited by one species. The aquarial stock from which these snails originated grew to a size almost four times that of its offspring in the spring. Only in an isolated, subsidiary spring, a few yards from the main spring, did specimens reach a size comparable to the aquarial stock. In all likelihood the differences in size exhibited by the seven sample populations in the spring have been brought about by ecological and not genetic factors. Not only are the means of shell lengths and maxi- mum sizes of shell considerably varied, but the points at which ma- turity is reached are correspondingly shifted. This latter fact ex- cludes the premise that these colonies represent aggregates of smaller, younger individuals. No direct correlation between diminutive size and type of bottom, depth of water, temperature of water, amount of shade, or distance from source of spring could be found. The small colony in the adjacent subsidiary spring attained a shell size nearly three times that of colonies in the main spring. Relatively few speci- mens per square foot were found in the smaller spring, while in the main spring overcrowding was evident, sometimes reaching a popula- tion density of 400 specimens per square foot. It is likely that food availability is the most important factor, but controlled experiments alone will support this assumption. 100 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 TaBLE 3.—Data pertaining to collections from Lithia Spring, Fla.

Table 3 shows the results obtained from 11 sample collections taken from Lithia Spring, Hillsborough County, Fla., in February 1947. The stations are marked on the map of the spring (fig. 41). Stations 6, 8, 9, and 11 had insufficient numbers of specimens to ascertain a reliable point at which maturity is reached, or a significant mean of shell length. The map has been marked with short arrows, which indicate the main flow of the current of water coming from the spring and with iong, broken arrows, which indicate the flow of river water that breaks across the low land to the north of the spring during flood periods. The river water, which is 18° C. in contrast to the 25° C. of the spring water, is fatal to these snails and undoubtedly accounts for their absence or low numbers at stations 8, 9, and 11. These last-mentioned stations are well stocked with local Florida snails (pleurocerids, amnicolids, and planorbids). The mean shell-length data given in table 3 is of little value in making a comparison of two populations, and, in fact, can be very misleading. A look at the population-growth curves of shell length (fig. 42) will reveal the fallacy of the mean shell length. Most of the populations give a bimodal curve, as accentuated in population 4. The first peak is simply an aggregation of immature specimens, a factor that will vary according to the reproductive cycle of that population and that will change in value as the young grow to an adult size. In population 4, maturity is reached at 6.5 mm. and extends up to 12.5 mm. The mean for these adults, which are continually growing, is about 7.5 mm., yet if the entire population, both immature and adult specimens, is averaged, the mean must be recorded as 5.5mm. This difficulty may be avoided in great measure by comparing only adults, SNAIL HOST OF ORIENTAL LUNG FLUKE—ABBOTT 101 > Vo) ‘ _ 7 > > = ‘\ , 7 7 a is ti a a ae \ ee oa \ e aie 2 \ Qan Oy Vs A ee NV y | LITHIA SPRING San ei | / / if vA Ficure 41.—Map of Lithia Spring, Fla., showing collecting stations (1 to 11) and water currents.

It is interesting to note the distance separating the mode of the immature curve and that of the adult curve in each population. Were these distances proportionately the same in each population, we could safely assume that the production of young was brought about simul- taneously throughout the various populations of the spring and was 102 PROCEEDINGS OF THE NATIONAL MUSEUM Vou. 102 NO.

Circles denote point at which maturity is reached. due to a seasonal, environmental stimulus. However, the distance between the “wave” of young and the adults varies considerably from 6 mm. in population 7 to 0 mm. in population 3. The latter popula- tion, which is unimodal, may represent a population in which the “wave” of immature has grown into the mature class, and it is not unlikely that it was bimodal a few weeks before the date of collection, in the manner of the other populations. The independent but pronounced production of young in the various populations suggests a cyclical activity in the physiology of the population itself, in which a fluctuation of sexual activity is present. How frequently these waves of young are produced could not be ascertained from data gathered on one visit to the spring. McMullen (1947), in his studies on the growth rates of the fresh- water snail Oncomelania quadrasi Moellendorff in the Philippine Islands, found similar smaller peaks or waves in the measurements of colonies. By revisiting his collecting areas periodically he was able to watch these waves of young move slowly toward the main peak of the adults. From his data he was able to ascertain that that species reaches maturity in 4 to5 months. I have shown also (1946) that similar waves occur in the developmental stages of the eggs of Oncomelania, and that this was due to increased egg production brought about by the stimulus of rains and flood periods. SNAIL HOST OF ORIENTAL LUNG FLUKE—ABBOTT 103 Bronomics or GuAm coLonies.—A natural sequence to the bionomic study of the Lithia Spring populations was an investigation of the same species living on Guam Island to see if similar environmental influences on size existed in areas natural to this species. In making a statistical study of the 13 colonies collected on Guam Island it was found that two serious drawbacks existed that, indeed, are common to any material of this nature. The first was that in most of the colonies an insufficient number of preserved animals were available to ascertain at what point maturity was reached. Secondly, the speci- mens were collected by hand and not in a strictly random fashion, as would be the case had a sieve or hand net been employed. The natural tendency of the collector is to choose the largest specimens first, then the smaller ones, until patience or time halts collecting. Despite these handicaps, it was felt that a reliable index of size could be obtained by using the 10 percent of that part of the colony that represents the largest specimens. This method would be open to criticism were we dealing with animals which stopped growth at maturity, and which possessed some distinctive morphological adult character. When neither of these markers are present, as is the case with this genus of mollusks, we seek the maximum growth to which the snails grow and eliminate an abnormally low mean, owing to high percentage of young. The choice of the 10 percent figure is arbitrary, although, in population samples of 50 or more, the chances are that this will include only adults. It is unwise to choose simply the largest one or two specimens, for it is common knowledge that abnormal giants or perhaps polyploids are apt to be present in any population and will not serve as representatives. This is the reason why, in smaller samples, of 20 or less, it is best to choose the 20 or 30 percent representing the largest specimens, for comparative purposes. What we are essentially seeking in a study of shell length is the largest size to which individuals will grow in any one population. Since growth is continuous throughout the life of the individual, two factors will delimit the length of shell—genetic and environmental. We have seen in our study of the Lithia Spring populations that some environmental factor is most likely responsible for length of shell, and it is not unreasonable to assume that such is the case in any dif- ferences found on Guam. On this island the streams are close to each other, and accidental dispersal by birds and other creatures is likely to keep the chances of a lengthy genetic isolation very low. To compare the 10 percent representing the largest specimens of each population is, in essence, to compare the ecologic conditions of each stream. In order to test the validity of using the 10 percent referred to of each colony, histograms were made of the 13 colonies, and the means of shell length were calculated for the total population and for the top 10 percent. Figure 43 is a summation of this study from colonies A to 104 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 M, with the histograms in the right column and the means, to their left, represented by straight lines. The upper line is the mean for the entire population sample, and, the line below, the mean for the top 10 percent. These two lines could never have the same length, but the nearer they come together, the more natural will be the curve. Any preponderance of young would lower the mean for the entire popula- tion. It will be noticed, from a comparison of the proximity of the two means and the configuration of the histogram, that colonies such as A, B, E, and K, in which the two means are closest, have more compact histograms approaching the normal curve. (L is based on only 8 specimens and cannot be considered significant for this purpose.) On the other hand, samples D, F, and especially G and J, whose two means are relatively far apart, possess histograms that are consider- ably distorted and drawn out by a high percentage of young. A résumé of the statistics is given in table 4.

In reality, it answers only the question “how large does this species grow in this environment?” A map of the southern half of Guam Island has been drawn and is presented in figure 40. The collecting localities for colonies A to M have been spotted, and the relative size of the top 10 percent of the individuals entered in the form of outlined shells. It will be noted that there is no geographical cline evident in their distribution. The only possible correlation noted is that between size of the large streams and size of large shells, but unfortunately insufficient studies of the SNAIL HOST OF ORIENTAL LUNG FLUKE—ABBOTT 105 COLONY MEANS HISTOGRAMS Ficure 43.—Means and histograms of population samples from Guam Island (see p. 103 for explanation). flow of these streams at various seasons were made. It would be interesting to mark and to transplant snails from, say, Agana Spring to Umatac River to see if final growth conformed with the latter environment. A reciprocal transplant would be equally illuminating. EFFECT OF EROSION ON SHELL LENGTH.—Whenever the water of the habitat of fresh-water mollusks becomes acid, there is apt to be a 106 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 marked effect on the shells and, in cases where the pH is less than 6.0, sometimes the death of the entire colony results. Many mollusks have developed a chitinous periostracum that protects the shell from cor- rosion. However, the abrasive action of sand particles and the attach- ment by algae or egg cases of Neritina gastropods may break through this outer covering and expose the calcium carbonate of the shell to the acid waters. It is not uncommon for some colonies of Thiara granifera to be considerably eroded at their spires. Shell-length measurements, in these cases, can hardly serve as fair comparisons with colonies that have suffered no loss of shell. The effect of erosion may be avoided by comparing the width of shells or the height of the last two or three whorls that have not been affected. However, it is of equal interest to learn exactly what amount of reduction in length has been brought about by stream action, for ecologists may wish to know not only the pH values of various streams but also what effect acidity is having on the animals. A study was made of a population sample of 257 specimens of 7hiara granifera (Naujan River, Mindoro Island, Philippine Islands, U.S.N.M. 258890) which showed considerable erosion. It was found that adults were reduced in shell length by 11.6 percent. Since this type of study has not, to our knowledge, been previously used, we have gone into considerable detail. ] | ‘ | | | 1 4mm. ig MM. 125 { MM. 25 MM. Ficure 44.—I.

Therefore, the upper histogram carries the effect of erosion, and the lower one is without it. Numerous small individuals were not worn away at their spires. These were measured for width and length to ascertain the ratio between these two figures (i. e., the obesity of the shell). The results are shown in table 5.

Having obtained this figure, which would represent a population size unaffected by erosion, we need only to compare it with our actual measurements of eroded specimens to ascertain the amount of reduction. This direct conversion could not be applied in this case, however, for the histogram is strikingly bimodal and in its lower peak possesses a number of young that were not worn away at the spires. The entire sample, therefore, was arbitrarily divided into groups A and B. As natural a midpoint as possible was chosen between the two peaks in the lower histogram at 6.75 mm. If the erosion-correction factor is applied to this (1.51 x 6.75), we obtain a theoretical equivalent total shell length of 10.19. It so happens that this figure divides the two groups in the upper histogram in exactly the same numerical propor- tion (i. e., 114 in group A and 142 group B) as we have in the lower histogram. 108 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 This division into two groups has put all the few perfect specimens in group A and has left us “adult” and all eroded specimens (except 1) in group B for comparative studies.

This is due to the youth of the group, which has been exposed to erosion for a relatively short time. In fact, 27.1 per- cent of these specimens were without a trace of spire erosion. In group B, representing adults that have been exposed to acid waters for considerable time, the reduction has been 1.17 mm., or 11.6 percent. PARASITOLOGY TREMATODE Parasites.—This species of fresh-water snail is of par- ticular interest to parasitologists because of its ability to serve as an intermediate host of numerous trematodes, three of which have been known, in their adult stages, to parasitize man. Other genera and species of the snail family Thiaridae also have this intermediate host ability, and their presence in the Orient is responsible for large endemic areas of the human lung fluke (Paragonimus westermani). In the course of dissecting specimens from many localities, it was noted that some colonies in the Philippine Islands were infected as high as 20 percent with unidentified heterophyidlike cercariae. Dis- section of specimens from the introduced colonies at Lithia Spring, Fla., failed to show any trematode infection. SNAIL HOST OF ORIENTAL LUNG FLUKE—ABBOTT 109 A résumé of the parasites carried by this species is given here. Iden- tification of the intermediate snail hosts as “Melania obliquegranosa Smith” is unquestionably referable to Vhiara granifera (Lamarck). I have examined specimens with the above identification from Formosa Island and the illustrations published by Japanese parasitologists, and I find that the implicated Formosan species is a minor race of the widespread subspecies 7’. g. mauiensis Lea.

Definitive hosts —Lungs of mammals, especially the felines and man. The life cycle was first elucidated by K. Nakagawa in Formosa in 1917. “When the snails are placed in water containing miracidia, the latter swarm around them and become attached to the heads, Jaws and feet, but rarely to the tentacles and mantles. They cling with their suckers, insert proboscis into the tissue of the host and enter the body of the snail like the cercariae of Schistosomum [sic] japonicum, as de- scribed by Miyairi (1915). Unlike the miracidia of Schistosomum, those of the pulmonary distoma Paragonimus shed their cilia in this act. “Besides the cercariae, sporocysts of various sizes are found abun- dantly in the liver of Melania [+Zhiara and Semisulcospira]. They are sometimes found in the heart and kidneys.” (Nakagawa, 1917, pp. 301-302). REMARKS ON SNAIL HOST SPECIFICITY.—Gastropod mollusks serve as the obligatory first intermediate host of all digenetic trematodes or flukes. While in several cases the relationship between the parasitic fluke and the host snail is restricted to one species in certain areas, on the whole there does not appear to be any set pattern for certain snails to serve as hosts to any particular spe¢ies or even genus of trematode. Of the three important blood flukes that infect man, Schistosoma japonicum appears most restricted in its choice of only one genus of snails, Oncomelania. In the Philippine Islands, Oncomelania guadrasi Moellendorff is the only known carrier; in Japan, only O. nosophora Robson. This genus of snails is a gill-breathing amni- colid. Yet Schistosoma mansoni Sambon and S. haematobium Bil- harz, of Africa and tropical America, are carried by the snails Bulinus, Physopsis, and Australorbis, all of which are lung-breathing Planor- SNAIL HOST OF ORIENTAL LUNG FLUKE—ABBOTT t11 bidae. The phylogenetic relationships of these two groups of gastro- pods could hardly be farther apart. In all likelihood the choice of mollusks is based on the physiological adaptations and ecological preferences of the snails in each case. Thiara granifera serves as host for two different superfamilies of trematodes, the Heterophyoidea (Metagonimus, Haplorchis, and Di- orchitrema) and the Troglotrematoidea (Paragonimus). ‘These same trematode groups are also carried by other genera of Thiaridae (Semz- sulcospira, Hua, Goniobasis, and the subgenus of Tiara called Mela- noides). In addition, however, members of the snail families Amni- colidae and Synceridae may also act as intermediate hosts, in some cases being the only snail hosts in the local endemic area. In all likelihood Thiara granifera may be considered a potential host cf the American Paragonimus kellicottii on epidemiological and eco- logical grounds. An understanding of snail-host specificity will probably not arrive from a study of molluscan phylogeny, but rather will have to await an intensive study of the physiology of the many fresh-water species that serve as hosts. The seeming tendency for certain families of snails to serve as hosts to particular groups or species of flukes is probably merely an expression of a common physiological condition possessed by these snails. INTRODUCTION INTO THE UNITED STATES Thiara granifera has established itself some 5,000 miles east of its normal geographical limits in the Lithia Springs of Hillsborough County, Fla. The thriving American colonies should be considered as potential hosts for one or more of the trematodes that they are capable of carrying in their native habitats. (See under Parasitology, p. 109.) It appears, however, for the several reasons discussed subsequently, that no danger exists in the establishment of these snails in our country. It appears from the information now at hand that there was only cne introduction of the snail into the United States. On March 23, 1935, an aquarium dealer of San Francisco, Calif., sent four specimens to the United States National Museum for identification. In a letter (March 23, 1935) to Dr. G. S. Myers, then curator of the division of fishes, this dealer states, “I do not know just where their native habitat might be, because here and there, from different points, Australia, China, Hawaii, etc., where I get a small shipment, plant life comes along and some small ones [snails] may be adhering to it.” No further notice was taken of this species, since at that time the parasitological importance of this species was overlooked. It was not until 1947 that it reappeared, when Dr. C. Wythe Cooke, of the U. S. Geological Survey, collected a number of specimens in Lithia Spring, iia bY PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 Fla., and kindly forwarded them to the United States National Mu- seum. A few weeks later I was sent to this spring to determine its prevalence, manner of introduction, and its possible spread. Thiara granifera is present in the main Lithia Spring in extraordi- nary numbers, sometimes as many as 400 specimens per square foot. A small, connecting subsidiary spring contains a few larger individ- uals. A fuller account of the spring condition appears in the section on bionomics (p. 100). An aquatic-plant and fish dealer in Tampa related that he acquired specimens in 1937 while on a visit to California. Since that time, his plant vats have been stocked with this mollusk which, as an oddity, had been sold over a hundred times in a year as the “Philippine horn of plenty.” It was his opinion that the snails were probably acci- dentally introduced to the spring around 1940, when improperly washed tubs were used to gather native plants. I have seen specimens in home aquaria in Silver Spring, Md., which had been acquired from Washington, D. C., dealers. It will be seen by the above experiences that any foreign snail that has sales value because of its attractive appearance or peculiar habits will soon be distributed to many parts of the country and in many cases will be introduced purposely or accidentally to native waters. Probably the most likely solution to the problem of con- trolling introduced, dangerous mollusks lies in encouraging dealers, particularly the importers, to send their mollusks for identification to museums that have specialists in mollusks on the staff. The present programs of the Bureau of Plant Quarantine and Insect Control and the United States Public Health Service appear to be extensive enough for our protection. It must be realized that even the most stringent of laws prohibiting the import of foreign mollusks are not going to offer perfect screening, since accidental introductions by various means are likely to occur. In the past hundred years approximately 50 species of exotic species of land and fresh-water mollusks have estab- lished themselves in the United States and Canada. The geographical origin of these snails will probably remain un- certain. From the condition and size of individuals in the Lithia Spring colonies, it appears that an abnormally stunted ecological form exists, which makes fair comparisons with races from endemic Pacific areas difficult. The more closely resembling lots in the United States National Museum are from the Hawaiian and Marianas Islands. They are possibly members of the subspecies or geographical race Thiara granifera mauiensis Lea, 1856. It is highly unlikely that this snail will spread to many other sec- tions of the United States, except in rare spring localities where water SNAIL HOST OF ORIENTAL LUNG FLUKE—ABBOTT 113 temperatures remain above 75° F. Its public health menace is negli- gible by virtue of the complex life cycle of the parasite that it is capable of carrying. A second intermediate host, usually a fresh- water crayfish or crab, is a necessary part of the life cycle of Paragonimus. Furthermore, in order to accomplish infection of the definitive host the crayfish must be eaten raw, a custom which is infre- quent or rare among our people. IDENTIFICATION OF THIARA GRANIFERA AND CLOSELY RESEMBLING SPECIES IN THE UNITED STATES In addition to a snail of similar appearance, which is native to Florida springs, there are two species of thiarid snails sometimes found in aquaria that are likely to be confused with T’hiara granifera. Pleurocera (or Ceriphasia?) catenaria (Say) is found in the same habitat as 7. granifera at Lithia Spring, but rarely succeeds in an aquarium. Hemisinus cubanianus (Orbigny), from Cuba, and Pachychilus glaphyrus (Morelet), from Central America (Honduras), have been raised by fish fanciers with moderate success. ‘The synopses of distinguishing characters presented herewith will aid in identify- ing these species.

MUSEUM Vol. 102 Washington : 1952 No. 3293 SOME MARINE ASELLOTE ISOPODS FROM NORTHERN CALIFORNIA, WITH DESCRIPTIONS OF NINE NEW SPECIES By Rosrerr J. Menzies In THIS report certain of the species of the isopod families Mun- nidae and Janiridae from northern California are described. The recorded species were all collected from the intertidal zones, with the exception of Janiropsis magnocula, which was taken from about 30 fathoms off the California coast. Hitherto only the genus /aniropsis, represented by two (really one) species, had been known from the California coast. In order to eliminate repetition, those characteristics mentioned in the family diagnoses are not mentioned in the generic diagnoses; furthermore, characteristics enumerated in the generic diagnoses ap- ply to the specific diagnoses and descriptions as well. Tn all instances, the width of specimens is taken at the widest part of the second peraeonal somite; the length is measured on the mid- line from the rostrum to the tip of the telson. Dr. Fenner A. Chace, Jr., curator of the division of marine inver- tebrates, United States National Museum; Dr. Melville Hatch, Zo- clogy Department, University of Washington; and Dr. Frank A. Pitelka, Zoology Department, University of California, have all as- sisted through the loan of certain specimens utilized in this report. Dr. Chace and Dr. Hatch kindly lent some type specimens, which proved very helpful in clearing up the confused concept con- cerning Janiropsis kincaidi kincaidi. Most Monterey County speci- mens were lent by Dr. Pitelka. They form part of a fine collection 956648—52——-1 117 118 PROCEEDINGS OF THE NATIONAL MUSEUM you. 102 of isopods, made by John Davis, which was deposited in the Univer- sity of California collections and subsequently lent me for study. To these gentlemen I extend my sincere thanks for their kind as- sistance. Family MUNNIDAE (Cf. Nierstrasz and Schuurmans Stekhoven, Jr., 1930, p. X, e 108) Genus MUNNA Kroyer, 1839 Munna Kr¢gyer, Naturh. Tidsskr., vol. 2, p. 612, 1889. (Genotype, Munna boeckii Kré¢yer, 1839.) Generic diagnosis—In general the generic diagnosis is modified after G. O. Sars (1897-99, p. 106). Body subpyriform, with dorsal surface somewhat vaulted; last three peraeonal somites small, with lateral parts directed somewhat posteriorly. Cephalon usually broad. Pleotelson consisting of two somites: A narrow, short, anterior somite and a pyriform last somite. Eyes distinct (G. O. Sars, 1897-99) or Jacking (H. J. Hansen, 1916, p. 34). First antenna with a 3-jointed peduncle and a flagellum composed of only a few joints. Second antenna with a 6-jointed peduncle and a multiarticulate flagellum. Mandible with a well-developed molar process, palp 3-jointed. Maxil- liped with a 5-jointed palp. Gnathopods of adult male subchelate, often enlarged and swollen. Remaining peraeopods ambulatory, not subchelate, increasing in length, with carpal and propodal joints much elongated and bordered with spinelike 2-pointed setae; dactylar joint small, biunguiculate. Uropods with one (?) or two branches. Remarks.—Even today this genus remains inadequately understood and contains a vast number of species. The genotype, Munna boeckii, is still imperfectly known, especially in respect to the minute structure of the mouth parts, uropods, and pleopods. For that reason the di- agnosis here given is very liberal, and I believe that once the genotype is better known it will be possible to divide the genus into at least two, and perhaps more, very distinct genera. It has been possible to detect on the species that I have examined a minute but clearly dis- cernible dorsal (outer) uropodal branch, which usually has but a single seta at its apex, and which generally is concealed partly or totally by the edge of the pleotelson. This isa rather significant observation, in that the genus Afunna has long been considered different from the other genera belonging to the family Munnidae in lacking biramous uropoda, e. g., “uropoda very small, simple” (G. O. Sars, 1897-99, p. 106); “uropoda small, simple” (Richardson, 1905, p. 480); “mit kurzen eingliedrigen uropoden” (Vanhdéffen, 1914, p. 561) ; “uropoden einiistig” Nierstrasz and Schuurmans Stekhoven, Jr. (1930, p. X, e 108) ; “uropoder enkla” (Hult, 1937, p. 9); et cetera.1 It is believed 1 After the preparation of this paper, Dr. Raymond Amar (1948) discovered an additional uropodal branch in Munna petiti Amar. MARINE ASELLOTE ISOPODS—MENZIES 119 that the omission of reference to this minute dorsal uropodal branch has been due to its being overlooked by the several researchers who have worked on the genus, and that it will in all probability be found on the other species belonging to the genus. Of course this makes the differentiation of Munna from related genera a more difficult task, but at the same time it indicates closer affinities. In three of the examined species a small but distinct squama was detected on the third joint of the peduncle of the second antenna. In a fourth species, I. ubiquita, there was only a slight indication of such a scale, in the form of a large seta. Reference to this observation, like that concerning the dorsal uropodal branch, appears to be lacking in the published description of species of Munna to which I have had access, and this character appears to have been overlooked. The squama also indicates a closer affinity between Munna and its related genera. As mentioned, it is possible to divide Munna species into several groups, some of which may become recognized genera when I. boeckii is better known. The following attempt at a division of the genus, while obviously incomplete, seems none the less worthwhile: A. Species having a leaflike, flattened, ventral uropodal branch lacking spinelike protuberances. Each male first pleopod not ex- panded laterally at apex, apex pointed. Gnathopods of adult male and female specimens similar. Male third pleopod with terminal joint of exopod not equal in width to width of terminal joint of endo- pod. Probably includes Munna nana Nordenstam, Munna acarina Miller, Munna petiti Amar, and Munna ubiquita, new species. B. Species having rounded (in X-section) ventral uropodal branch bearing at least one large spinelike protuberance. Each male first pleopod expanded laterally at apex. Gnathopods of adult male en- larged and swollen, unlike those of adult females and subadult males. Male third pleopod with terminal joint exceeding in width the width of terminal joint of endopod. Probably includes Munna avatshensis Gurjanova, M. kréyeri Goodsir, M. palmata G. O. Sars, W/. stephenseni Gurjanova, and If. chromatocephala, new species. C. Species similar to those in B, except ventral uropodal branch ap- pears to lack any large spinelike protuberance. A distinct, dorsally visible, dentate, suburopodal shelf is present, which structure is lack- ing in species mentioned in B. Probably includes Munna minuta Hansen and Munna halei, new species. D. Species lacking eyes. Minute structure of mouth parts, pleopods, and uropods not known. Equals Coecimunna Richardson, 1908, and includes Munna truncata Richardson and M. acanthifera Hansen. E. Species to which such assignments are impossible at the present time, owing to their being inadequately known. Includes a vast majority of the species. 120 PROCEEDINGS OF THE NATIONAL MUSEUM vou. 102 The four species herein recorded, three of which are new, represent the first intertidal records for the genus from California.

Marin County, Dillon Beach, First Sled Road, January 21, 1948 (R. J. M.), 8 males, 13 females; Tomales Bluff, Tomales Point, bay side, August 18, 1947 (R. J. M.), 1 specimen; in tide-pool plankton haul, November 29, 1947 (R. J. M.), 3 specimens; Tomales Bay, Marshalls, shore-line plankton haul, November 13, 1947, 11 specimens, mostly ovigerous females (R. J. M.). Hcology.—This species appears to be one of the most abundant species of intertidal marine isopods at localities near Dillon Beach, and because of its apparent ability to thrive in vastly different ecologi- cal conditions I have given it the name wbiquita. Specimens were found on the Bryozoa Bugula pacifica and Tricellaria occidentalis and in most tide pools and shore-line plankton hauls. The species appears intertidally abundant in both protected bay and exposed rock-coast localities. Specimens taken from Tomales Bay demonstrated a posi- tive phototropism in the laboratory. Ovigerous specimens were noted during January, October, and November. Remarks.—An examination of some paratypes of Munna acarina Miller (1941, pp. 311-313, fig. 2) indicates that the species is closely related to Uf. ubtquita. ‘The specimens were kindly lent by Dr. Miller from his personal collection. Munna nana Nordenstam (1933, pp. 222-295, figs. 56-57) similarly appears closely related to U/. ubiquita; however, in the paper cited Dr. Nordenstam makes no mention of the species having 2-branched uropods. In a letter recently received from Dr. Nordenstam he remarks that he has been unable to find a dorsal uropodal branch on specimens of Munna nana.

SreyskaL Cottecrions made during recent years by members of the armed forces in the course of malaria-control work and similar activities have added materially to our knowledge concerning the flies of the family Tylidae in areas not covered in Hennig’s recent (1935-1936) mono- graph. This and other material in the United States National Museum were made available to me through the kindness of the au- thorities of the Smithsonian Institution, and study has led to the following results: Eleven new forms are described, for one of which a new genus is erected. The genus Afimomyrmecia is transferred from the sub- family Trepidariinae to the Taeniapterinae, and descriptive notes are given. Examination of material determined as Furybata hexapla has revealed a compact group of species around that form and the fact that other species placed in the genus are abundantly distinct. A new genus, based upon the second species referred to EHurybata, E. semilauta Osten-Sacken, has been set up for the latter group. Sufli- cient material was examined to make possible a preliminary study of the subspecies of Mimegralla albimana, a “Formenkreis” widespread in the East and Oceania. Geographical spellings are taken from maps of the National Geo- graphic Society, especially those of the Pacific Ocean (December 1936) and southeast Asia (October 1944), except that Japanese forms of names for islands formerly under Japanese mandate are not used. 161 956650-—52———-1 162 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 Family TYLIDAE Subfamily TAENIAPTERINAE Genus GRAMMICOMYIA Bigot 1.

Hennig (1985, p. 200) cites MZ. a. galbula from the Philippine Is- lands (Palawan, Mindanao, Luzon) and Taiwan (several localities, including Lambe Island). Our extra-Philippine material is gener- ally a little smaller and paler; the dark femoral bands are narrower or reduced to indistinct spots on the dorsal side of the femora and the wing pattern is very indistinct; but the Philippine specimens also vary in these respects and it is deemed unwise to recognize any dis- tinctions. The Palau Islands material varies enough to bring it well within the limits of galbula. 3d. MIMEGRALLA ALBIMANA CONTRARIA (Walker) Calobata contraria WALKER, Proc. Linn. Soc.

Our Admiralty Islands material is most nearly typical, with distinct wing bands and a strong hind femoral pattern, including a distinct preapical dark band. A wide variation exists, however, in the coloration of this form and although some evidence of a cline toward the east is present, some of the specimens from Bougainville, Florida, and New Georgia approach those from the Admiralties. 3f.

Remarks.—Since this species runs in Hennig’s key (1935, p. 83) to Mimegralla leucopeza, it may be a subspecies of that form. However, the general yellowish color is more extensive than in any race of J. leucopeza, and the wide separation from the nearest station of that species (M. 1. albitarsis, Manila, Philippine Islands) also makes doubtful its identity with leucopeza. 10.

Examination of the above material has revealed that the genus is definitely taeniapterine, rather than trepidariine, as Hennig, in the lack of material, presumed it tobe. It will run in my key to the genera of African and Oriental Taeniapterinae (1947, p. 6) to couplet 3, the first three characters of the first alternative suit. The arista, how- ever, is plumose. The aflinities seem to lie definitely with @Grammi- comyia, but the development of the back of the head into three pro- tuberances distinguishes Mimomyrmecia from any other Paleotropical genus. TOWNESA, new genus Genotype.—T ownesa spinosa, new species. Very similar to Mimegralla, to which genus it will run in my key (1947, p. 6), agreeing in all particulars. The type of Mimegralla, M. coeruleifrons (Macquart), as well as all other species of Mimegralla known to me, has no armature of any kind on the fore femora. Townesa, however, has a row of 8 to 12 strong bristles nearly as long as the diameter of the femora along the whole length of each lower side of the fore femora of the male, and 3 to 5 similar but somewhat smaller bristles on each side of the apical half of the fore femora of the female. The legs are very long and uniformly slender; the first 172 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 posterior cell of the wing is very narrow apically but not closed; the second vein exceeds the level of tp by the length of tp, postvertical bristles are lacking; two well-developed anterior frontals are present definitely within the tomentose mesofrontal area; the posterior frontals are about opposite the anterior ocellus; and the bristles of the mesonotum include 1 de, 2 sa, and 2 strong ntpl. The arista is dis- tinctly and abundantly short plumose. Remarks.—I take pleasure in naming this genus in honor of the discoverer of its type species, Dr. H. K. Townes. 12.

Head with mesofrons black-tomentose; parafrontals shining black with bluish reflection; medifacies brown with black lower margin; clypeus, palpi, and antennae brown, the antennae with third joint black above and in apical half and with arista black apically, brown at base, and furnished with short plumosity. Thorax lightly greenish-brown-pruinose on pleura and sternum, dark-brown-pruinose on notum, except broad sublateral greenish sub- shining stripes, which meet anteriorly across the anterior hump.

Genus EURYBATA Osten-Sacken On examining a series of specimens included in Lurybata hexapla it became evident to me that Osten-Sacken was correct when, in deserib- ing the second species of Lurybata, EF’. semilauta, he stated that later authors might see fit to place it in another genus. Hurybata may be distinguished from Crosa, new genus (p. 176), which is based upon £/. semilauta, as in the foregoing key, by the characters of the head rep- resented in figure 74, a, b, and in the male by a lack of long hairs on the basal ventral side of the fore femora. The abdomen is shining apically and near the segmental sutures. It was also evident that two new species were included with £. hexapla. These species are included in the following key to the species of the restricted genus Hurybata. All species are known only from the Philippine Islands. 2The genus Mimomyrmecia Frey has been removed from this subfamily (see p. 171). The genera Formicosepsis De Meijere and Cypselosoma Hendel have been referred here by Hennig (1941), although Hennig has later (in litt. Sabrosky, 1949) indicated that Cypselosoma is a clusiid. These two genera may be distinguished from all other Tylidae by the possession of strong vibrissae and ocellar bristles. Calycopteryr Eaton, from the Kerguelen and Heard Islands, a fly with rudimentary wings, has also been referred here by Hennig (1934). 174 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 KEY TO SPECIES OF THE GENUS EURYBATA OSTEN-SACKEN 1.

Color yellow, except extreme tip of femora and tibiae, dorsum of abdomen and anterior part of parafrontal stripes, which parts are brown. There is a faint preapical band of brown on fore femora and the apical tarsal joints are a little darkened. Mesofrons golden brown, becoming blackish in ocellar region. The entire insect is shining or subshining except mesofrons, frontal orbits anterior to parafrontal stripes, antennae, and a heavily tomen- tose pleural stripe. Anterior frontal orbits narrowly golden tomen- tose. Pleural stripe bright white when viewed very obliquely, but otherwise dull lead colored; it covers the narrow lower margin of propleura and continues across mesopleura as a stripe as wide as fore tibiae. ‘The stripe, were it to continue across the sternopleura, would run into the uppermost two posterior sternopleural setae. Para- frontal stripes with a bluish reflection. Head very similar to that of C. semélauta (fig. 74, c, d), but aristal hairs only half as long as in that species. Wings clear hyaline with brownish-yellow veins. Third and fourth veins converge to within a distance equal to length of ta.

Although the two known species of Westima, VN. polita Osten- Sacken, and NV. prolixa (Walker), are both inadequately described, I believe that the above specimen agrees well enough with Osten- Sacken’s description to make the determination. There must remain some doubt as to the identity of the following forms, described as new, but I feel certain that they are specifically distinct. AUSTRALASIAN STILT-LEGGED FLIES—STEYSKAL 179 21. NESTIMA PLEURALIS, new species Female.—Length 10 mm., exclusive of ovipositor. Similar to Osten- Sacken’s description of WV. polita, although the thorax is not “uni- formly dark brown, shining,” but moderately pruinose on dorsum with a pitchy brown, largely polished band of equal width extending all around thorax, including entire pteropleura, crossing notopleural suture, and including neck, humeri, and anterior face of anterior hump of mesonotum. Below this band on pleura of each side is a heavy stripe of appressed white hair, very narrow above fore coxae end gradually widening to include entire hypopleura from middle coxal to pteropleural sutures. There are several whitish sternopleural bristles and 1+2 notopleurals. Lower part of thorax is yellow. Fore trochanters are black; fore femora yellow at base and at tip for a distance equal to three times the width, preceded by a blackish band of approximately same length; fore tibiae blackish except at extreme base; and fore tarsi whitish except two brown apical joints. Middle and hind legs have tips of tibiae and entire tarsi black. Halteres with brown stem and yellow knob. Type—Holotype, female, U.S.N.M.

Very similar to NV. polita and N. pleuralis. Thorax dark brown, moderately prui- nose on dorsum, blackish in a humeral stripe on each side of anterior hump. Mesopleura with pitchy, shining stripe in upper part, taper- ing and becoming evanescent forward. No trace of pruinosity or hair on pleura anterior to hyposternopleural suture. Several whitish sternopleural bristles and 1+2 notopleurals. Fore legs yellow; tibiae light brown on most of length, yellow basally and whitish apically; tarsi whitish, but brownish on apical two or three joints; middle and hind legs yellow, except black tips of tibiae and entire tarsi.

NATIONAL MUSEUM Vol. 102 Washington: 1952 No. 3295 APHOTAENIUS, A NEW GENUS OF DUNG BEETLE (COLEOPTERA: SCARABAEIDAE) By O. L. Cartwricut A new South American beetle, which I discovered as I studied the collection of Aphodiinae (Coleoptera: Scarabaeidae) in the United States National Museum, has certain characters, especially those of the hind tibiae, that are shared by Ataenius carolinus Van Dyke. These peculiar characters, which have precluded the satisfactory in- clusion of carolinus in any known genus of the Aphodiinae, would seem to indicate the advisability of setting up a new genus for the reception of both species. APHOTAENIUS, new genus General shape elongate oval, very convex, lateral edges of elytra and pronotum posteriorly not visible from directly above. Head moderately large, smooth except for a band of coarse punctures across occiput. Clypeus shallowly emarginate, finely reflexed margin flattened and dorsally angulately widened between two widely placed marginal teeth or denticles, when viewed from directly above the widened margin appearing as an angulate carina and hiding extreme lower edge, which has a much smaller median angulation directed in the opposite direction. Genae bent downward as in Ataenius. Pronotum not crenate, not fimbriate, posterior angles truncate-obtuse, slightly depressed. Pygidium as in Ataenius, the anterior basal por- tion with a longitudinal groove receiving the ventrally dentate tips of the elytra, the exposed apical portion with a depressed central area. Middle and posterior tibiae with distinct oblique carinae as in Apho- 956657—52 181 182 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 dius but without the apical fringe of spinules, the apical margin ventrally with two well-separated triangular teeth, each tooth with a very fine hairlike seta basally on each side, the outer apical angle spinelike as in Ataentus. Mouthparts as in Ataendus. Genotype.—Ataenius carolinus Van Dyke=Aphotaenius carolinus (Van Dyke). A photaenius, though having distinct oblique carinae on the middle and hind tibiae as in Aphodius, should be placed in the tribe Eupariina, since the head, genae, pygidium, and other parts are much closer to Ataenius and allied genera than to Aphodius. The middle and hind tibiae are unique. APHOTAENIUS CAROLINUS (Van Dyke) Ataenius carolinus VAN Dyker, Pan-Pacific Ent., vol. 14, p. 157, 1928. Aphodius carolinus Hinton, Ann. Mag. Nat.

Head three-fourths as wide as pronotum, strongly convex, basally with a band of coarse punctures, front finely punctate, anterior smooth, impunctate; clypeus with finely reflexed margin, bidentate, teeth strongly developed, acutely pointed and widely separated, slightly emarginate between teeth, margin flattened and dorsally angulately widened, this appearing as an angulate carina from directly above, the extreme ventral margin, invisible from above, with a small median angulation directed in the opposite direction. Pronotum convex, margined basally and laterally, surface with mixed coarse and very fine punctures, coarse punctures uniformly distrib- uted, separated by less than one to two diameters. Elytra convex, coarsely striate, striae strongly crenate punctate, intervals moderately convex, minutely punctate. Covered basal portion of pygidium deeply grooved under tips of elytra, exposed portion with depressed eroded area divided by a longitudinal carina. Posterior prosternal spine strongly developed, laterally compressed. Mesosternum closely moderately punctate. Metasternum quite closely coarsely punctate, median longitudinal line deep. Second abdominal segment closely shallowly setigerously punctate along anterior margin, carinate be- tween the coxae; remaining segments smooth, coarsely deeply crenate in front.

Remarks.— A photaenius carolinus is a common species in deer drop- pings in June in Pisgah Forest, near Brevard, N. C., and was taken there as early as April 29 and as late as September 10. It has been taken in sheep droppings on Sassafras Mountain, S. C.; in rather old cow dung in woods near Pine Mountain, Ga.; and in the same in V’On Swamp, Fair Lawn Plantation, 7 miles from Awendaw, near Charleston, S. C. Mark Robinson and I collected several specimens at the last-named place on June 4, 1948. These were the first seen from other than mountain localities, except possibly a single specimen in the M. A. Cazier collection bearing an old and very doubtful label, “Key West, Fla.” Recently a single specimen was found in an early private collection of H. S. Barber, which had been determined by E. A. Schwarz as “Aphodius n. sp.” This specimen bears label data as follows: “Marlboro, Md. May 13. Collection H. S. Barber.” It was probably collected between 1898 and 1901. Still more recently I found a specimen in the Blatchley collection at Purdue University. This specimen of Aphotaenius carolinus was collected in Crawford County, Ind., May 19, 1908, by W. 5. Blatchley and was erroneously reported as Ataenius lecontet Harold in his “Catalogue of the Coleoptera in Indiana.” APHOTAENIUS COLOMBIENSIS, new species Piceous black, shining, anterior margin of head and thorax and legs reddish, antennae and palpi testaceous. Head about three-fourths as wide as pronotum, strongly convex, basally with a band of close moderate punctures, front with more widely spaced fine to minute punctures; clypeus slightly depressed and emarginate at middle with a low angulation or denticle each side, lateral margins finely reflexed, genae bent down as in Ataenius, margin between denticles flattened and dorsally angulately widened to twice the height of the denticles, this appearing as a carina from directly above, lower edge of widened margin, invisible from above, with a small median angulation in the opposite direction. Pronotum convex, laterally and basally mar- gined, not fimbriate, anterior angles obtusely rounded, posterior angles truncate-obtuse, slightly depressed, base distinctly lobed medially, surface with mixed fine and coarse punctures, the latter generally distributed but closer laterally, separated by one to four or five diam- eters on the disc.

Wuitre As a part of the salvage program of the River Basin Surveys, a cooperative project between the Smithsonian Institution, the National Park Service, the Bureau of Reclamation, and the Corps of Engineers, Department of the Army, in the prospective reservoir sites in the Mis- souri Valley, the Boysen Reservoir area near Shoshoni, Wyo., has been prospected for vertebrate fossils for parts of two seasons. During the first period, from October 23 to November 7, 1947, I worked alone, and considerable time was lost because of early snows. The area was again worked, with the aid of John C. Donohoe, a student at Montana State College, and Ernest L. Lundelius, a student at the University of Texas, from June 4 to July 12, 1948. Although the specimens have not been credited to individuals, I wish to state that these men have proved themselves competent collectors, and we three found about equal amounts of material. Although it is planned to visit this area for as many seasons as possible before the reservoir is flooded, it seems de- sirable to make the information gathered to date available to other paleontologists. 185 956647—52——-1 186 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 SYSTEMATIC DESCRIPTION OF FOSSIL VERTEBRATES Class REPTILIA Order SQQUAMATA Suborder SERPENTES Family BOIDAE Genus BOAVUS Marsh BOAVUS cf. OCCIDENTALIS Marsh About 30 associated thoracic vertebrae (loc. No. 48FR78);1 2 thoracic vertebrae (loc. No. 48F R80). Although there is considerable difference in size between the two specimens, I am inclined to be extremely cautious about differenti- ating species of snakes on the size of the vertebrae only, since age is not readily reflected in the surface texture of the bone. Consequently, the principal importance of this material is the presence of this genus in the Lost Cabin faunal zone of the Wind River formation.

Discussion.—This specimen, in conjunction with a braincase from Pipestone Springs (U.S.N.M. No. 18805), permits a few additions to Gilmore’s (1928, 1938) discussions of the genus. The various elements that make up the braincase are securely fused, as in Peltosaurus. The former location of some of the sutures can be made out by lines of roughened bone. The condyle is elongate-oval in outline, twice as broad as deep. The tubera basioccipitalia project ventrolaterally from the basicranial axis and are expanded anteriorly and posteriorly at their bases as though reinforced by flying but- tresses. ‘These expansions are thickened along their edges so that the 188 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 tubera are triradiate from their terminations, with the median portion the heaviest. ‘The foramen for the twelfth cranial nerve is located beside the condyle and below the paroccipital process, at the termina- tion of the posterior wing of the tubera basioccipitalia. The ninth and tenth nerves exit through a dorsoventrally elongated foramen at the ventral side of the jugular groove a little posterior to the median portion of the tubera basioccipitalia. The fenestra ovale lies just above this foramen. The foramen for the exit of the venus capitis lateralis lies just above the anterior termination of the anterior wing of the tubera at the bottom of the jugular groove. The foramen for the hyoid branch of the seventh nerve lies at the top of the jugular groove slightly posterior to the foramen for the venus capitis lateralis. A thin, fairly deep ridge of bone extends downward from the paroc- cipital process of the prodtic so that the jugular groove is partially enclosed laterally. The region of the hypophyseal fontanelle is so badly damaged in both specimens that reliable data cannot be obtained. The basiptery- goid processes of the basisphenoid are elongate and flattened as in most Sauria. They are separated from the tubera basioccipitalia by a deep notch, which extends to the main body of the basisphenoid. The anterior edge of the prodtic is damaged in both specimens, but enough of this region is preserved in U.S.N.M. No. 18316 to indicate that the ossification of the prefacial commissure very nearly or en- tirely encircled the facialis branch of the seventh nerve as it left the braincase. A fragment of the maxilla in U.S.N.M. No. 18317 shows that the anterior maxillary teeth are much smaller than the posterior teeth. They increase rapidly in size to the fifth tooth, which is as large as the remainder. The collection of Glyptosaurus material in the United States National Museum, which contains most of the types, was examined in connection with this material. Many of the species were founded on the characters of the frontal and interorbital regions only, and as yet some of the species are known only from the type specimens. Although the taxonomy of a genus based on such a limited portion of an animal leaves much to be desired, it is possible to make a morpho- logical grouping of the species of this genus by means of the characters presented by this region of the skull. Only with the aid of better material can the validity of this grouping be determined. The known species are tentatively grouped as follows: I. Interorbital region with four rows of osseus scutes with one or two odd seutes interpolated between the median rows__--------- G. montanus group IY.

No. 18483, fragment of left mandible with M, (loc. No. 48F R80). If the skull is correctly referred to this form its characters are sufficiently distinctive to warrant designation as a separate species, rather than citation as a mutation of D. absarokae. The distinctive characters presented by the teeth of this specimen are : P? two-rooted, anterior and posterior cingula well developed and with minute erenulations; P* submolariform and differs from P* only in being slightly smaller; M‘ exhibits several minute tubercles on the external cingulum between the parastyles and metastyles. Other characters 190 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 of the teeth agree with Matthew’s (1918, p. 583) figures of D. absarokae. Although this skull is very badly broken and crushed, it adds a few details to our knowledge of the genus. Because /ctops is relatively well known, comparisons will be made with it, although the two forms are not closely related: (1) The frontonasal suture les a short distance in front of the orbit. (2) The zygoma is a little heavier than in Jctops. (8) Post- orbital process is short but very well defined. A companion process was not observed on the fragment of the zygoma preserved. (4) The orbit appears to be as large relatively as in Zetops. (5) The sagittal crest is single and moderately high. (6) The parietal foramen appears to lie closer to the crest than to the squamosal. (7) Squamosoparietal Ficure 76.—Didelphodus ventanus Matthew, U.S.N.M. No. 18369; occlusal view of left P?-M3, X4. foramina were not observed. (8) The union of the mastoid portion of the petrosal and the squamosal appears to have been similar to that in Jctops. (9) The mastoid appears to form as much of the occiput as in Jetops. (10) The relationship of the glenoid to the periotic suggests that the postglenoid and posttympanic processes of the squamosal were separated by a meatal notch, although these processes were broken away. (11) The tympanic ridge of the ali- sphenoid is lacking, but there is a short one on the glenoid portion of the squamosal. (12) The foramina in the alisphenoid appear to have been much the same as in Jetops, but this region is badly crushed and difficult of interpretation.

There appears to be some confusion in the literature concerning the size range of the lower molars of this species. Osborn (1902, p. 185) in the original description gives the size range from 11 to 13 millimeters. Loomis (1905, p. 422) found that his material exhibited a uniform measurement of 12 mm. Matthew (1915b, p. 317), in his key to the species of the genus, gives the length of the lower molars as 10mm. In the material from the Boysen Reservoir area, the two specimens with M,; have a molar length of 13 mm. In all the speci- mens the length of M._; varies between 8.0 and 9.0 mm. Van Houten (1945, p. 425) pointed out that most of the Lower Eocene genera could be revised profitably. ‘This is certainly true of Hyopsodus. Hyopsodus wortmani has never been adequately characterized in the literature, and if this material is correctly referred, the lower dentition may be characterized as follows: P, submolariform, anterointernal style well developed and joined to the protoconid by a distinct crest; deuteroconid well developed; anterointernal style, protoconid, and deuteroconid forming a distinct trigonid; heel well developed and trenchant, hypoconid centrally placed and prominent, entoconid small and indistinct from posterior cingulum; M, with metaconid distinctly twinned, crescents on protoconid well developed, hyopoconulid and entoconid distinct, anterior and posterior cingula present; M, similar to M, except that metaconid is indistinctly twinned; M, long and nar- row, narrowing rapidly from in front posteriorly, hypoconulid as large as, or larger than, hypoconid and forming a distinct heel; entoconid small but distinct, metaconid may or may not be indistinctly twinned. This material is not readily distinguishable from H. paulus Leidy, of the Lower Bridger, by size, but the teeth of the type are so badly worn that their characters cannot be properly evaluated.

The characters that this limited material presents are as follows: Dp; with posteroexternal crescent well developed, cross-crest between hypoconid and entoconid well developed, hypoconulid small but dis- tinct, external and posterior cingula present; Dp, with anterior and posterior external crescents well defined, metaconid distinctly twinned and higher than protoconid, cross-crest between hypoconid and entoconid well developed, entoconid higher than hypoconid, hypoconu- lid small but well defined, well developed anterior, external, and posterior cingula. The deciduous teeth described here are somewhat higher crowned than the permanent teeth, and can be distinguished from the perma- nent dentition of Orohippus only with difficulty. In fact, these teeth were originally referred to that genus and it was only after Dr. C. L. Gazin and I spent some time comparing them with the material in the U.S. National Museum that their true identity was learned. I have been told by Morris Skinner that this characteristic—the deciduous teeth of horses being more advanced than the permanent teeth—has been observed in the later Tertiary horses. In view of the growth processes involved in the formation of horse teeth (White, 1942, p. 26) it is logical to correlate the above phenomenon with the activities of the endocrine glands, which stimulate and regulate BOYSEN RESERVOIR VERTEBRATE FOSSILS—WHITE 199 growth, during the period of postnatal development (ibid., p. 45). That the thyroid (Goldzieher, 1939, p. 83) plays an important role in influencing the morphogenic processes, particularly in the ossification of the skeleton and in the growth of the teeth, has been demonstrated by the administration of thyroid extract to hypothyroid children and by thyroidectomy of normal laboratory animals. Its action is by no means independent but is closely integrated with that of the pituitary, parathyroid, and adrenals. Nor do these glands function only in com- bination with each other but in combination with the other glands of the system to maintain an endocrine balance and a favorable “internal environment” or homeostasis (ibid., p. 11). In order to maintain homeostasis the endocrine glands must respond to external factors. The changes in external environment that are accompanied by changes in the activity of the glands are: Altitude, temperature, climate, quantity and type of food, and accessory food- stuffs such as mineral salts and vitamins. The data on the responses to these factors are limited almost entirely to the clinical observations on man and laboratory animals. These data indicate that when less than radical changes in the external factors prove deleterious there is a strong probability that an endocrine imbalance already existed (Goldzieher, 1939, pp. 11-13). Of equal importance to the activities of the endocrine glands are the responses of the receptor tissues to the stimuli of the hormones. These responses may be affected by a variety of factors, such as: The condition of the tissues, ennervation, chemicals, and the age and stage of development of the individual. With regard to the two last- mentioned factors, which are probaby the most fundamental, little is known except that the responses of the tissues are characteristic of the stage of development. Thus, in a young and growing individ- ual, the response to hormones is growth and maturation, while in the adult the hormones are capable only of maintaining the orderly function of the tissues (Goldzieher, 1939, p. 6). It is a well-known fact that in animals there is a noticeable slowing down of growth soon after puberty, though the postpubertal growth period may be as long as the prepubertal. However, this may be due to the interaction of the endocrine glands. In regard to the environment offered by this region during Lower Eocene time, Van Houten (1945, pp. 442-444) characterizes it as a humid lowland with a warm-temperate to subtropical climate sup- porting a luxuriant vegetation of both woodland and savannah types. As to the soils, the parent rocks from which they were derived were igneous (extrusives and intrusives) and sedimentary (limestones, dolomites, shales, and sandstones). Weathering processes would make available phosphorus, potassium, calcium, and some sodium from 200 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 the igneous rocks and calcium and magnesium from the limestones and dolomites. The result would be a very fertile soil containing an ample supply of all the minerals necessary for a luxuriant and nutritious vegetation. In view of the above considerations, it can be concluded that this region offered a very nearly optimum environment for herbivorous animals, and that factors which would seriously disturb the endocrine balance were absent. The estrogens and androgens (sex hormones) (Goldzieher, 1939, p. 289) and the hormone of the adrenal cortex (ibid., p. 93) have an inhibitory effect on the thyrotropic hormone of the anterior lobe of the pituitary, which results in decreased activity of thethyroid. Although estrogens and androgens are present in nearly all foods (ibid., p. 748) and growing plants, and do not appear to be altered by the processes of digestion, they are not secreted in quantity by the gonads till a short period before puberty. It is believed that only a portion of these hormones taken with food find their way into the blood stream. It has been shown that these hormones are inactivated in the liver and are rapidly destroyed by oxidation in the lings (ibid., p. 748), which greatly reduces their effectiveness when administered by mouth. In view of the role played by the thyroid in the formation of the teeth by its effect on metabolism and growth, the low estrogen and androgen content of the blood while the deciduous teeth were being formed could result in the advanced type of teeth. That the third permanent premolar is more advanced than the fourth in some species of Hyracotherium (Granger, 1908) may be due to the sudden increase in the estrogen and androgen content of the blood during the interval between the formation of these two teeth. If the appearance of the physiological brake on the thyroid furnished by the secretions of the gonads and the adrenal cortex were postponed until after the deter- mination of the form of the permanent teeth by the growth of the tooth germ, it is conceivable that the advanced type of tooth would result. In view of the antagonism between the gonads and the thyroid (Goldzieher, 1939, p. 94), such a deferment could be the result of mild hyperthyroidism.

SUMMARY Since Tertiary reptiles are yet too poorly known to be useful as horizon markers, they will be omitted from the summary. From the Boysen Reservoir area 23 species of fossil mammals have been identi- fied; 14 of them (see Table 2) are common to the Lost Cabin faunal zone of the Lower Eocene, 2 of them to the Gray Bull, and 2 others are common to both the Gray Bull and the Lysite. Consequently, there can be little doubt that these deposits must be referred to the Lost Cabin faunal zone. However, on structural grounds these beds may be somewhat younger than the type section on Alkalai Creek. There are about 250 feet of the Wind River formation exposed in the Boysen Reservoir area. For the most part the formation consists of drab greenish-gray gypsiferous clays with yellowish, usually fine- grained, channel sandstones forming nearly vertical cliffs.

NATIONAL MUSEUM Vol. 102 Washington: 1952 No. 3297 A NEW CRAYFISH FROM ALABAMA, WITH NOTES ON PROCAMBARUS LECONTEI (HAGEN) By Horron H. Hosss, JR. THE COMBINED ranges of the members of the Blandingii section of the genus Procambarus, excluding mountainous areas, extend from Mexico to Massachusetts, and from Florida to Ohio and Minnesota. The new species described herein is found in a region in which the members of this section have shown the greatest degree of speciation (i. e., in the southeastern part of the United States). Since the species is represented in my collection by only six specimens, taken from the type locality, little is known of its habits and variation, and its range can be postulated only in terms of the known distribu- tion of its close relatives, which presumably have similar habitat preferences. On the basis of the latter it seems probable that it is confined to the Tallapoosa River and its tributaries. Procambarus lecontei (Hagen, 1870, p. 47) has never been ade- quately diagnosed, and the published figures (first pleopods, antennal scale, and epistome by Hagen, 1870, and dorsal aspect by Faxon, 1885a) are inadequate and not entirely accurate. Furthermore, since its original description there has been considerable confusion as to its range. In addition to presenting a revised diagnosis of P. lecontei and illustrating the diagnostic features, I am including a bibliography of the species and summarizing its known range. I wish to express my gratitude to Dr. E. C. Raney, R. D. Suttkus, and J. Kezer, of Cornell University, for the gift of the specimens on which the new species is based, as well as to others, mentioned in connection with collection data, who have assisted in collecting specimens of P. lecontez. 967611—52 209 210 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 Abbreviations used to indicate repositories of specimens are as follows: HHH, my personal collection at the University of Virginia.

First pleopod of first- form male with no marked hump on cephalic surface but with a noticeable “knob” on lateral surface opposite the caudal process; tip terminates in four distinct parts (of which all except caudal proc- ess are directed caudad at approximately a right angle to main shaft of appendage): mesial process long, slender, subcylindrical, non- corneous, lies considerably proximad of and extends much farther caudad than the other terminal elements; cephalic process moderately short, compressed, corneous, and somewhat hoods the more prominent central projection; caudal process slender, somewhat flattened, corneous, lies proximad of the central projection, and is directed at about a 45° angle to the main shaft of the appendage; central projec- tion compressed, corneous, beaklike, and extends slightly farther caudad than either cephalic or caudal processes. Annulus ventralis as in fig. 81, d, decidedly broader than long with a prominent raised area on cephalolateral (dextral or sinistral) side of sinus; sternum immediately cephalad of annulus with multituberculate prominences which extend caudad to cover a portion of annulus. 1In part, excluding records from Georgia, Florida, Mississippi, and North Carolina.

Remarks.—F axon (1885a, p. 30) has discussed the locality records cited by Hagen (1870, p. 48), and has indicated that only the speci- mens mentioned by the latter that were collected from Mobile, Ala., belong to Procambarus lecontei.2, Following his discussion of Hagen’s locality records he stated that “besides the Mobile types, I have found but one other specimen of this species in the Museum, a young female in a jar with @. spiculifer (Cat. No. 172), from Athens, Ga.” I have examined this specimen, which is in a poor state of preservation, and am uncertain as to its identity, but even if it should prove to be lecontei there is every reason to doubt the reliability of the label. I have collected on several occasions in the vicinity of Athens, and have received numerous collections made by Dr. Donald C. Scott from that region, and neither of us has found P. lecontet. In fact, only two species belonging to the genus Procambarus have been found in the Athens region: P. spiculifer (LeConte, 1856, p. 401) and P. pubescens (Faxon, 1884, p. 109). Furthermore, no other specimen of lecontet has been reported east of Mobile County, Ala. Thus P. lecontet is known only from the southwestern part of Alabama and the southeastern part of Mississippi, where it is found in tributaries of the Mobile and Pascagoula Rivers. PROCAMBARUS VERRUCOSUS, new species FIcure 82 Diagnosis —Rostrum with small lateral spines or tubercles, which set off the acumen from basal portion; areola moderately narrow with 2T may add that the specimens from Pensacola, Fla., which Faxon stated were not leconteit but of which he made no specific determination, are Procambarus evermanni (Faxon, 1890, p. 620) [MCZ No. 249].

The specimens on which this description is based were collected by Dr. E. C. Raney, of Cornell University, on March 24, 1948, and he has kindly furnished me with the following data: At this locality the stream is clear, about 10 feet wide and 3 feet deep, sandy-bottomed, and with a volume flow of 5 cubic feet per second. The stream flows through an open pasture, and at the time the collection was made the temperature of the air was 80° F., and that of the water 65° F. Disposition of types —The holotypic male, form I, allotypic female, and morphotypic male are deposited in the United States National Museum (No. 90743). The paratypes, consisting of one male, form I, one male, form IT, and one female, are in my personal collection at the University of Virginia (No. 3-2448-3b). Relationships —Procambarus verrucosus, « member of the Bland- ingii group (Hobbs, 1942b, p. 341), has its closest affinities with Pro- cambarus blandingii acutus (Girard, 1852, p. 91). However, it may readily be distinguished from it by the more complexly appearing annulus ventralis of the female, and the structure of the first pleopod of the male. The caudal knob of the first pleopod has assumed a markedly different position in P. verrucosus from that in some of the other species of this group, in which this knob more closely resembles that of the hypothetical generalized pleopod (Hobbs, 1942a, p. 58). In P. hayi (Faxon, 1884, p. 108) the caudal knob (which has been prolonged proximally into a long irregular fold) lies on the caudo- lateral face of the appendage at the base of the caudal process; in P. blandingii acutus, while the caudal knob is distinctly knoblike, it has shifted caudolaterad and lies at the cephalolateral base of the cephalic process; in P. verrucosus there has been a still stronger degree of shifting in a cephalic direction so that it forms a rounded shoulder on the cephalic border of the appendage. Were it not for the in- termediate stages of shifting of the “caudal knob” which have been observed in specimens tentatively identified as P. blandingii acutus (a subspecies that has never been clearly defined) one would hardly suspect that the “shoulder” on the pleopod of P. verrucosus had any relationship to that of the more “typical” caudal knob as occurs in P. pictus (Hobbs, 1940, p. 419) and the “less typical” one in P. havi. Remarks. —The annulus ventralis of the allotype contains a sperm plug, which indicates that this species breeds in the early spring; however, it should be pointed out that this does not mean that this species does not breed during summer, fall, or winter. 218 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 Collected with P. verrucosus in the type locality were five specimens of P. versutus (Hagen, 1870, p. 51).

Frevp THE TWO genera of moths! treated in this paper are found only in the Greater Antilles and the Bahama Islands. Until the present time they have been treated as a single genus with three species, Mulona lapidaria Walker, Mulona nigripuncta Hampson, and Mulona grisea Hampson.' A careful study of the 47 known specimens from the collections of the United States National Museum, the British Museum (Natural History), the American Museum of Natural History, the Carnegie Museum, and Cornell University, disclosed two genera and six species involved in the complex. Palpal, antennal, and venational characters are identical in the two genera treated in this paper and are given here to avoid repetition in the generic descriptions. Labial palpus upturned, reaching middle or slightly above middle of frons. Antenna of male and female fili- form and gradually more slender to the tip; each subsegment with two pairs of bristles, one from near or above middle of ventrolateral margin of subsegment, the second much smaller and just behind the first; subsegments pubescent. Venation of forewing with vein 2 from middle of cell or from just before or after middle, downward curved at base; vein 3 from just below lower angle of cell; veins 4 and 5 sepa- rate, 4 from lower angle, 5 from slightly above lower angle (in one of the 5 specimens of Lomuna nigripuncta Hampson, 4 and 5 are con- nate or extremely short stalked); vein 6 from below upper angle of cell; vein 9 from stalk of 7 and 8 or rarely 7 from stalk of 8 and 9; 1 The species Autoceras phelina Druce was placed in Mulona by Hampson (Catalogue of the Lepidoptera Phalaenae in the British Museum, vol. 2, p. 387, 1900). It does not belong in Mz/ona and was transferred to the genus Gaudeator Dyar by Forbes (Bull. Mus. Comp. Zool., vol. 85, No. 4, p. 183, 1939). 967606—52 221 222 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 102 veins 10 and 11 free; vein 10 from middle or nearer stem 7, 8, and 9 than to 11; vein 11 from beyond middle of cell and curved toward 12, distally coincident with 12. Venation of hindwing with vein 2 from outer third of cell or beyond; vein 3 stalked with 4 from lower angle of cell; vein 5 absent; vein 6 separate from 7 or sometimes connate or stalked with 7 (in the single female specimen of Mulona manni), 6 from upper angle, 7 from before upper angle of cell; vein 8 from before middle of cell. — KEY TO THE INCLUDED GENERA, BASED UPON GENITALIA 1.

Palpi dark fuscous except along ventral surface, where color is white. Head, antenna, and thorax white, sometimes pale yellow or brown on thorax.

Fore- wing below nearly white along hind and outer margins, pale brown over rest of wing. Hindwing above and below entirely white. Specialized scales found in grisea near costal margin of hindwing are absent in nigripuncta. Legs as in grisea. Length of forewing, 8-8.5 mm. Male genitalia as illustrated (pl. 10, fig. 1). Female.—Habitus similar to that of the male. Forewings above irrorated with black scales. This irroration sometimes heavy and therefore habitus sometimes much darker than male. Forewing below entirely light fuscous, sometimes paler along hind margin. Hindwing above and below pale fuscous, nearly white or pale gray in base of wing. Length of forewing, 8-9 mm. Female genitalia as illustrated (pl. 11, fig. 7). Type locality—Probably Puerto Rico. Norz: Hampson cites th type locality as “Colombia” and his type is labeled “nigripuncta, Z., Columb., M. Ber.” in Zeller’s own handwriting. It is a specimen that Zeller intended to describe and the specimen came originally from the Berlin Museum. This species is known only from Puerto Rico and is not known from Colombia. The species of this group and other closely related groups are very limited in their distribution and hence it is extremely doubtful that the type of nigripuncta came from Colombia. Additional type data.—Described from a single specimen, the holo- type, female (locality cited as Colombia but probably is Puerto Rico; collection Zeller; Berlin Museum; 92 genitalia preparation, British Museum No. 1947-273). Hampson also cites Puerto Rico as a habitat for nigripuncta but he does not list number of specimens or sexes for this locality. He had evidently seen specimens other than the type from Puerto Rico; however these were not before him at the time he wrote his original description, hence the single specimen mentioned above is indeed the holotype. Distribution.—Purrto Rico: District of Guayama, Palmas Abajas, near Guayama (June); District of San Juan, Manati (June), Bayamon (July); District of Aguadilla, Lares (July); District of Mayagiiez, San German (April). Five specimens examined. Remarks.—The genitalia of the type of nigripuncta was compared with the figure of the female of this species (pl. 11, fig. 7) by D. S. Fletcher of the Department of Entomology, British Museum (Natural History). He found the type of nigripuncta to be the species there illustrated. ‘230 PROCEEDINGS OF THE NATIONAL MUSEUM VoL. 102 PLATES The drawings for figures 3 and 3A were made by the author from a photograph of the genitalia of the type. These two drawings were corrected and modified by D. S. Fletcher, of the Department of Entomology, British Museum (Natural History), by comparison with the actual type preparation. Arthur D. Cushman, of the U. S. Bureau of Entomology and Plant Quarantine, made the drawing of the bursa copulatrix and ductus bursae in figure 8 (from an imperfect specimen in the Carnegie Museum) and the drawings of the remaining figures. The rest of figure 8 was drawn from the type by Mr. Fletcher. The following figures were based upon the preparations of the holo- types of the respective species: 3, 3A, 4, 4A,5,5A,6and6A. Figures 9, 10, and 11 were drawn from the allotypes of the respective species. Figures 1 and 1A were drawn from slide W. D. F. No. 1651, 1941. Figures 2 and 2A were drawn from slide W. D. F.

S. NATIONAL MUSEUM Vol. 102 Washington : 1952 No. 3299 A NEW SPECIES OF COMMENSAL AMPHIPOD FROM A SPINY LOBSTER By Ciarence R. SHOEMAKER In January 1942 the late E. F. Ricketts, in connection with the work of his Pacific Biological Laboratory, at Pacific Grove, Calif., examined a living spiny lobster Panulirus interruptus (Randall) at the local fish market. The lobster, which was presumably sent from Santa Barbara, had some amphipods adhering to its pleopods, and six of these were sent to me for identification. I find that these specimens represent a new species. The structure of the peraeopods indicates that they were modified and developed for the purpose of grasping, and the animals appear to have been living commensally upon the pleopods of the lobster. The mouthparts are of the normal type and are not modified in any way, thus indicating that the animal is not parasitic. The specimens are all females possessing partially de- veloped marsupial plates. PARAPLEUSTES COMMENSALIS, new species Figure 83 Female—Head with rostrum rather short and blunt; lateral lobes rounding; eye rather large, black, and reniform. Antenna 1: Pedun- cular joints short; first joint not twice as long as second; second joint not twice as long as third; flagellum about twice as long as peduncle and containing 14 joints (an unknown number of terminal joints are missing). Antenna 2: Peduncle short; fourth joint about twice as long as third and equal in length to the fifth; flagellum a little longer than peduncle and consisting of 13 joints. 231 967610—52 232 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 Right mandible with 10 or 11 teeth in cutting plate; no accessory plate; molar conical with very small triturating surface; 12 spines in spine-row; palp with third joint slightly longer than second and not apically produced.

U_ S. GOVERNMENT PRINTING OFFICE: 1952 PROCEEDINGS OF THE UNITED STATES NATIONAL MUSEUM issued SMITHSONIAN INSTITUTION U. S. NATIONAL MUSEUM Vol. 102 Washington; 1951 No. 3300 A NEW GENUS OF CENTRAL AMERICAN MILLIPED (FAMILY EURYURIDAE), WITH NOTES ON THE AMER- ICAN GENERA. By Ricuarp L. Horrman WHILE sortiINne out unidentified millipeds in the collection of the United States National Museum, I encountered a single male speci- men that represents an unnamed genus (here described) of the family Euryuridae. Investigation of pertinent literature has revealed sev- eral taxonomic errors that may be corrected at this time, and it appears that at least one genus (Polylepiscus) is readily separable into two more natural groups. Together with these various additions and emendations, I include new distributional records for two species of Amplinus, and a consid- eration of the known American euryurid genera with reference to some diagnostic characters whose value seems questionable. A tenta- tive key to the genera is provided. The Euryuridae is a small family (12 genera and about 50 species) with many of the characters of the Platyrrhacidae and with nearly the same distribution. Both families are represented in the Indo-Aus- tralian region and in tropical America; species of Huryurus and Auturus also invade the North Temperate Zone as far as Ohio and Minnesota. The most recent, and only complete, account of the Euryuridae is to be found in Attems’ monumental Polydesmoidea monograph (Das Tierreich, Lief. 68-70, 1937-1940). This manual lists all known spe- cies and because of its conservatism affords an excellent starting point for taxonomic studies. Attems combines the Euryuridae and 235 967609—52 236 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 Platyrrhacidae (Lief. 69, p. 202), the latter being represented in his arrangement by the single genus Platyrhacus. Seven other genera of Attems’ “Platyrrhacidae” have the characters of the Euryuridae as here understood. Since the appearance of Attems’ work, Chamberlin has described a number of species and genera from northeastern Peru (1941, Bull. Amer. Mus. Nat. Hist., pp. 498 et seq.). I wish to express my indebtedness to Dr. E. A. Chapin, curator, division of insects, United States National Museum, who has greatly facilitated my work at that institution; to R. L. Wenzel, division of insects, Chicago Natural History Museum, for the loan of many specimens from collections under his charge; and to Dr. Clarence J. Goodnight, department of biological sciences, Purdue University, who has kindly given me valuable material from his Central American collecting. | REMARKS ON TAXONOMIC CHARACTERS Attems’ key to the five American genera recognized by him is based to a considerable extent upon sculpture of the dorsum. H'wryurus and Pycnotropis are separated off in couplet 4 by the statement “Metazoni- ten glatt oder nur mit Spuren einer polygonalen Felder,” as opposed to “Metazoniten mit Querreihen grosser Tuberkeln,” which leads to Polylepiscus and Amplinus. This reliance upon tergite modification leads to considerable difii- culty. Even in the four genera mentioned, one finds smooth species in “tuberculate” genera, and vice versa. The issue is complicated by the addition of Chamberlin’s four Peruvian genera and one from Panama to be described herein. There seems to be such variability in the development of polygonal areas on the dorsum that its practical value is largely negated. The new Panamanian form keys out to Pycnotropis, and the gonopods are of the type found in that genus, but other characters are those of Phinotropis (Polylepiseus, in part, of Attems). Because of the difficulty attendant upon the use of sculp- ture, I believe it advisable to appeal to other characters, such as sub- antennal swellings, anal sternite, and male gonopods, for generic diagnosis. The following key appears to be satisfactory at present for the rec- ognition of American genera: 1The genus Aphelidesmus has been placed in the Euryuridae by recent American workers at one time or another, since the time of Cook (1895) and Pocock (1909). Despite its somewhat truncate terminal segment, Aphelidesmus properly belongs in the family Strongylosomidae, a group with somewhat distant affinities.

Good- night collector. This is the first definite locality for the species, which was described from “Central America.” The specimens at hand match the original 238 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 description closely. The prozonites are very dark brown, the meta- zonites light brown or tan; keels, antennae, legs, and last tergite yellow. In the male the apical prongs of the gonopod are not bent to the extent shown in Pocock’s figure, but the difference in this respect is hardly significant.

EURYURID MILLIPEDS—-HOFFMAN 239 Range.—The species is known to occur from west Florida north through Georgia (Indian Springs), Alabama (Auburn), and Ten- nessee to extreme northern Kentucky (Crittenden). Loomis was misled into describing falcipes by a misunderstanding of Bollman’s statement that the upper branch of the male gonopod of australis is five times as long as the lower. This refers to the branches in their position on the living animal. In Loomis’ descrip- tion and figure, the gonopod is reoriented so that the actual position is reversed. Bollman’s type of australis has been discovered at the National Museum and its gonopods verify this idea, matching per- fectly with the figure of falcipes. Genus PHINOTROPIS Chamberlin Phinotropis CHAMBERLIN, Bull. Amer. Mus. Nat. Hist., vol. 78, p. 499, 1941. (Genotype: P. tidws Chamberlin.) Range.—Northwestern Brazil, northeastern Peru, Ecuador. Species—Phinotropis acuticollis (Attems), braueri (Carl), kalo- notus (Attems), mammatus (Attems), ?rorert (Chamberlin), t¢dus Chamberlin. The original descr iption of Phinotropis is as follows: “This genus is erected for the species described below in which the male gonopods differ from those of 7Arinoxethus in having the major distal branch entire and distally acute like the minor branch.” Thrinowethus was characterized as follows: “Agreeing in general structure with Polylepiscus but differing in the form of the gonopods of the male. In these there are two distal branches of which one is distally acute and the other, larger one, furcate at its distal end .. .” Insofar as these two diagnoses alone go, it is obvious that Phino- tropis is identical with Polylepiscus as used by Attems and others. However, with the restriction of the latter name to Guatemalan species having three terminal processes on the male gonopod, Chamberlin’s name becomes available for the South American forms and must be used, although originally a synonym. Polylepiscus rorert Chamberlin, from Trinidad, is known only from the female type specimen, and probably pertains to another, possibly new, genus.

Approximate length, 51 mm.; greatest width, 6.9 mm. Head entirely smooth, glabrous except for a few fine hairs near labral margin. Clypeal furrow very distinct. A prominent trans- verse ovoid swelling directly below each antennal socket. Antennae rather stout, short, reaching back to anterior margin of third tergite; articles 2-6 of nearly equal size. Collum perfectly smooth, with a fine but distinct margining ridge except on caudal edge. Anterior edge nearly straight, caudal edge bent forward laterally. Lateral ends slightly truncate and marginal ridges more prominent than across back. Second tergite wider than collum and third tergite, its keels pronouncedly swept forward. Tergites completely smooth, except for extremely faint suggestions of polygonal areas on the keels, to be seen when the dorsum is dry. Keels of moderate width and length, never overlapping, set above middle of body and nearly horizontal, thus interrupting slope of the rather convex dorsum; anterior corners rounded off, posterior corners produced caudad into a point on all keels back of third seg- ment. Both anterior and posterior edges are set off by a marginal ridge. Lateral edges inflated and smooth but for a slight notch on the anterior shoulder. On poriferous keels the pores are lateral in a large swelling. On the 19th segment pores are definitely inferior on the small, distally rounded keel. Last tergite broadly truncate, nearly tongue shaped, lateral edges almost parallel. A small median terminal lobe. Anal valves smooth, with well-defined median ridges. Preanal sternite nearly semicircular without lateral setiferous tubercules. Last pair of legs separated by a distance equal to diameter of their coxae; penultimate pair slightly farther apart. Bases of all legs fused into a raised area very distinct from and higher than the prosternites. Legs long and slender, end of third joint visible past keels in dorsal aspect. Lengths of joints of legs, in order of decreasing length, 3, 6, 5, 2,4, 1. Terminal claw slender and nearly straight. No special processes associated with any of the legs. Sides and underparts all smooth and glabrous. A deep constric- tion between prozonite and metazonite. In going toward the head, the sternites tend to develop a small conical tubercle at base of each leg. Gonopod aperture of medium size, oval, with caudal and lateral raised edges. Pregenital legs unmodified. Seminal apertures small, in end of coxae of second pair of legs, no special processes for them. Gonopods: Coxa short with a long slender trachial process and a small hook just above exsertion of solenite. Prefemur and femur fused into a straight, heavy, upright trunk, somewhat concave on one side and densely setose; the opposite side is traversed by the seminal EURYURID MILLIPEDS—-HOFFMAN 243 groove. Terminal elements of gonopod (solenomerite and tibiotar- sus) set off by a distinct joint. Solenomerite long, gently curved across tibiotarsus, with a small distal expansion. ‘Tibiotarsus sig- moidally curved, with a subterminal lateral lamination, the outer edge of which bears three teeth; distally trifurcate with the median tooth the longest. Original color completely lost through preservation. Genus THRINOXETHUS Chamberlin Thrinowvethus CHAMBERLIN, Bull. Amer. Mus. Nat. Hist., vol. 78, p. 498, 1941.

S. NATIONAL MUSEUM Vol. 102 Washington: 1952 No. 3301 AN EMENDED DIAGNOSIS OF THE COPEPOD GENUS PUPULINA (CALIGOIDA), WITH DESCRIPTIONS OF NEW SPECIES AND A REDESCRIPTION OF THE GENO- TYPE By Mivprep Srratron WILson THE CALIGOID copepod parasite Pupulina has been an imperfectly known genus since its discovery in 1892. The original description by van Beneden was incomplete, and attached to it, as the description of the male, was the diagnosis of an immature female of another genus. Not until 1935 was its validity definitely established, by Dr. Charles Branch Wilson, through the description of both sexes of the genotype, Pupulina flores. One subsequent record of the species has been made, that of Bere (1936). This seeming rarity and the incompleteness of knowledge that always results when but a single member of a genus is known add interest to the recent discovery of two new species. These occurred together on a specimen of the giant ray M/obula lucasana Beebe and TeeVan, taken off the coast of California. The copepods were re- moved from its surface by Prof. G. E. MacGinitie, who referred them to the United States National Museum for identification. The host, the second of its kind to be drawn to the attention of science, was also of particular interest, and salient facts concerning it have already been noted in a publication by MacGinitie (1947). The collections of both Wilson and Bere are in the United States National Museum and thus, fortunately, available for study. A direct comparison of the new species with Pupulina flores has made possible a new, nearly more complete diagnosis of the genus; ; especially has it mmaeated the importance of certain characters fatherts not stressed or noted. In addition, it has been found that some of the 245 246 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 specimens identified by Bere as Pupulina flores are referable to the smaller of the two new species. A new description, based on the Wilson and Bere specimens, has been prepared for the genotype, as much detail having specific value has been previously omitted. Development forms, present in his ma- terial and not mentioned by Wilson, are also described. For critical readings of the manuscript I am indebted to Dr. Charles H. Martin, of Oregon State College, and to Paul L. Illg, of the United States National Museum. HOST RECORDS According to each of the three published instances of the occurrence of Pupulina, it has been found on a species of large ray belonging to the family Mobulidae. From this fact and MacGinitie’s discovery it would appear that the genus may be a specific parasite of this group of rays. It seems very probable that records of its occurrence have been infrequent because the hosts themselves are seldom caught. In this connection, it is necessary to qualify Wilson’s statement (1935a, p. 593) that his specimens, taken near the Galapagos Islands, were from “Manta birostris, the same species of fish as that from which Beneden’s specimens were collected.” Van Beneden did not so name the species of the host, merely alluding to it as Ceraptopterus. The latter is a genus of Coleoptera, and so far as is known to me, the name has not been used in the fishes. From van Beneden’s de- scription of the size of the host, it is probably safe to assume that he had confused the name with Ceratoptera Miller and Henle, a synonym of Manta. Van Beneden’s specimens occurred off the Azores, a locality considerably removed from the Galapagos, and whether the host was the identical species of Manta is certainly open to question. Genus PUPULINA P. J. van Beneden Pupulina VAN BENEDEN, 1892, p. 254.—C. B. Witson, 1935a, p. 593. Diagnosis (emended).—Body form of more or less specific varia- bility in females; strikingly similar in males. Frontal plates well defined, without lunules. First three thoracic segments fused with head; fourth segment free, without dorsal plates. Lateral, cephalic, and thoracic areas of carapace demarcated dorsally by well-defined grooves; ventral supporting ribs of lateral areas stout, the posterior of double rods, their outlines usually conspicuous dorsally. Genital segment of female moderately enlarged, its width greater than that of free segment, about one-half to three-fifths that of carapace; the posterior corners produced into backwardly directed COPEPOD GENUS PUPULINA (CALIGOIDA)—WILSON 247 lobes; dorsal surface with a large medial clear area in which the integument is considerably thinner than that surrounding it, creating in the mature forms a characteristic design for each species. Abdomen narrow and elongate in both sexes, 3-segmented in the female, the divi- sion between the first two segments sometimes indistinct ; 2-segmented in the male. Caudal rami linear in male; either linear or short and broad in female; terminal setae very short, sparsely plumose or naked. Second antenna of female with either two or three segments well defined, apical claw stout, basal segment with a strong, posteriorly directed spinous process; that of male 3-segmented, tipped with a stout claw and armed variously with laminae and spines. Prehensile lateral hooks present, the basal portion bearing posteriorly two papil- lae armed with branched or simple setae. Oral appendages similar to those of the Caliginae. Mouth tube in female constricted near the middle, its greatest width a little more than half the length of the entire tube; the whole more slender and hardly constricted in the male; opening subterminal. Mandible 4- segmented, segments 2 and 3 imperfectly defined, claw heavily chitin- ized, with teeth on the inside margin only. First maxilla consisting of two heavily chitinized pieces and a very small, membranous papilla, the outer chitin piece having its outside edge more or less produced distally, being extended in the genotype into an elongated process; the inner piece (usually referred to as endopod by recent writers) extended posteriorly into a slender spine- like process, in the male either branched distally or bearing an articu- lated spine. The papilla (the exopod of recent writers) arising from the ventral face between the basal portions of the two chitin structures ; bearing three comparatively short setae which exhibit sexual as well as pronounced specific differences. Second maxilla elongated; first segment imperfectly defined, represented by a slightly enlarged basal portion; third segment very slender, with two thin, curving, terminal claws, the posterior of which is much shorter than the other. Maxil- liped of female with short terminal claw, not more than half the length of basal segment; male having claw a little longer and the basal seg- ment variously armed. Two pairs of accessory processes arising from the ventral face, sexually similar. The anterior pair spinelike, situated near distal end of the inner chitin piece of the first maxilla. The posterior pair heavily chitinized or membranous, shape specifically variable, located behind the base of the maxilliped, directly opposite the posterior supporting lateral ribs of the carapace, but in nowise connected with them or with the central area usually occupied by the furca, which is lacking. Legs 1-3 biramose. Leg 1 with both rami 2-segmented, the endopod well developed ; the inside spine of the second exopod segment charac- QAS PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 teristically branched in each species. Curved chitin rods, sometimes armed with spines or spinous processes, between bases of legs 1 and 2. Leg 2 with trimerous rami; outer spines of exopod 1 and 2 only moderately developed; endopod 1 and 2 with outer marginal laminae. Leg 3 having both rami 3-segmented, their bases set closely together. Exopod well developed, the first segment elongate as in the second leg, outer spines weaker. Endopod 1 and 2 with outer laminae, that of segment 1 greatly enlarged and overlying the exopod, that of seg- ment 2 much smaller; the second segment the longest, with two inner setae arranged like those of the second leg; third segment approxi- mately the same size as the first segment, with four terminal setae. Leg 4 uniramose and stout; 4-segmented, the basal segment greatly broadened; somewhat sexually dimorphic in armature; some species having short spines on the inner margins of segments 2-4; the sutures between these segments transverse. No rudiments of legs 5 and 6 visible on genital segment of adult, but present on the ventral side in female chalimi; condition in immature male not observed. Length of known females, 6-15 mm. ; of males, 4.8-12 mm. Parasites of giant rays. Genotype —Pupulina flores P. J. van Beneden.

Locality: near the Galapagos Islands. Identified by Charles Branch Wilson. One female, U.S.N.M. No. 79150. Host: “probably Mobula hypos- toma (Bancroft).” Locality: Lemon Bay, Fla., Gulf of Mexico. Identified by Ruby Bere. Diagnosis.—Anterior (cephalothorax) and posterior parts of body approximately equal in length in both sexes. Processes of female genital segment reaching a little beyond the middle of the abdomen. Caudal rami attached terminally, linear; those of female only a little shorter than the abdomen; those of male longer. Outer chitin piece of first maxilla extended distally almost to tip of the process of the inner piece; the latter bifurcate in male. Maxilliped of male with a short papillalike process on the basal segment. Posterior ventral COPEPOD GENUS PUPULINA (CALIGOIDA)—-WILSON 249 accessory processes large, heavily chitinized, triangular spines. Leg 4 without inside spines on segments 2-4, but with a cuticular process on 4. Description—FEMate (pl. 12, fig. 1) : Galapagos specimens: Total length 13.9-15.0 mm. Carapace about 6 mm. long, 5.8-6.0 mm. wide. Gulf of Mexico specimen: The single, nonovigerous female only 10 mm. in length, but otherwise like the Galapagos specimens. Anterior margin of carapace curved, median sinus slitlike; posterior margin nearly straight. Grooving of carapace as in pl. 12, fig. 1; lateral lobes with long slender hairs dorsally; each side of distal edge of thoracic area set with four or five spines. Free segment about three times wider than long, with short dorsal spines posteriorly. Genital segment joined by short neck to the free segment, rounded anteriorly; posterior processes reaching slightly beyond midpoint of second segment of abdomen, ending in slender, rounded tips, diverg- ing inside directly from the base of the abdomen. Sides of segment and parts of dorsal surface set with very short spinules. Design on dorsal surface sloping in a wavy line from the rather straight top to the widened central area; the posterior part narrowed with a marked central incision of the entire bottom margin. Abdomen narrow and elongate, a little longer than the genital seg- ment in midline; the first segment very short and indistinctly defined ; the second and anal segments plainly demarcated from each other, the second twice the length of the anal; both distal segments with a midline of long, coarse hairs and scattered surface spinules; anal segment with a pair of dorsal longitudinal ridges distally. Caudal rami a little shorter than the abdomen, flattened laterally, proximally with a raised longitudinal ridge; dorsal margins set with coarse hairs; terminal setae very short and nonplumose, three in number. Ovisacs slender, longer than the caudal rami. The first antenna (pl. 14, fig. 9) with a double row of stout plumose setae on the upper side of the first segment and two short spines distad on the lower side; the narrowed terminal segment having a slender seta midway on the lower margin, and the apex set with numerous short spines and varied setae (pl. 14, fig. 8). Second antenna (pl. 12, fig. 4) 2-segmented, basal spinous process very slender, terminal claw curved inwardly, only moderately elongated. Lateral prehensile hooks (pl. 14, fig. 5) comparatively long and strongly curved, setae of basal papillae branched. Mouth tube as described for the genus; mandible with 12 teeth. The anterior accessory process of the ventral face (pl. 14, fig. 7) located near the distal inner side of the inner piece of the first maxilla ; consisting of a very stout spine about one-fourth as long as this portion of the maxilla. The outer piece of the first maxilla (pl. 12, fig. 8) well developed, its outer edge elongated and spinelike distally, reaching 250 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 beyond the middle of the inner piece; the papilla seemingly closely associated with the tissue of its inner basal portion. The three papil- lary setae unequal and unlike (pl. 12, fig. 15), the shortest having an accessory spine near its midline. The inner piece of the maxilla longer than the extension of the outer piece, ending in a similar stout, slightly curved spine. The second maxilla (pl. 12, fig. 9) of the long slender form charac- teristic of the genus, tipped with two slender, unequal claws with marginal hyaline flanges, the posterior about half the length of the other. The claw of the maxilliped (pl. 12, fig. 10) slender, about half the length of the basal segment, bearing a stalked seta on its posterior side. The accessory process just posterior to the base of the maxilliped (pl. 12, fig. 11) a very broad, stout, chitinous spine, irregularly triangular, with the distal point somewhat attenuated. (The basal part of this spine is probably a bar corresponding to that found in the other species, but the main body is so strongly chitinized that any division between the two is obscured.) Chitin rod between legs 1 and 2 narrow, curved backward, each side armed with a stout upwardly directed spine. Form of leg 1 as shown in plate 15, figure 14; endopod reaching to distal third of basal exopod segment; terminal exopod segment with the upper two spines stout and dentate on both margins, the modified inner spine and ac- companying seta as shown in plate 12, figure 16. Basal segment of leg 2 armed inside with a plumose seta and a triangular lamina. Exopod (pl. 12, fig. 18) with outer spine of first segment reaching to distal end of third; spine of third segment with smooth margins, reaching considerably beyond distal edge of seg- ment; second spine about one-third the length of the first, smooth and slightly curved. Laminae on outer margins of endopod segments 1 and 2 similar to those shown in plate 15, figure 12, except that the edges are more rounded. (There is no lamina on the inner edge of the second segment as stated by C. B. Wilson, 1935a. As is usual, the margin of the segment is extended beyond the point of attachment of the succeeding segment, and bears two long setae at the distal terminus of the extension.) The third segment rounded and very short, bearing six setae. The exopod of leg 3 having the basal segment as long as the two succeeding segments, the outer spines of segments 1 and 2 smooth, slender, and scarcely longer than the following segment. The inner setae not so long as those of leg 2. Segment 3 (pl. 12, fig. 14) with three outer unequal spines. The laminae of the outer margins of the endopod attached as shown in plate 12, figure 17; that of segment 1 very large and overlying the first two segments of the exopod. The inner Margin of segment 2 expanded as in leg 2. COPEPOD GENUS PUPULINA (CALIGOIDA)—WILSON 951 As my findings disagree with some of those of C. B. Wilson (1935a), the following summary of the armature of legs 1-3 is given (sp= spine; se=seta; Jam=lamina) : Exopod Endopod Leg 1 sp 0 3sp 4se 3se Leg 2 sp se lam se sp se lam 2se 2sp 6se 6se Leg 3 sp se lam 0 sp se lam 2se 3sp 4se 4se Basal segment of leg 4 (pl. 12, fig. 20) with small spines on anterior and posterior margins; second segment with similar spines along outer margin; none on margins of segments 3 and 4. ‘Terminal outer spines of segments 2 and 8 about as long as the succeeding segment, inner spines lacking. Distal end of fourth segment with three stout spines and one slender spine, the outermost shorter than the segment, the next as long as, and the third a little longer than the segment; the inner spine attached laterally, slender, curved, reaching beyond the end of the segment by one-half its own length; a thin, cuticular process, spinelike distally, present at about the middle of the inner margin. All large major spines of the leg coarsely toothed, the longest of the terminal segment having some of the teeth considerably enlarged on the inner margin, with three stout additional teeth on the outer side. Mate (pl. 12, fig. 3) : Total length 11.4-12.1 mm. Carapace about equal in length and greatest width, 5.1-5.4 mm.; cephalothorax about 5.8-6.0 mm. long. Posterior part of body averaging 5.8 mm. in length; of this the approximate divisions are: genital segment, 1.3 mm.; ab- domen, 1.9 mm.; caudal rami (exclusive of setae), 2.6 mm. The caudal rami are therefore longer than the abdomen, but are shorter than the genital segment and abdomen combined. None of the speci- mens, including the allotype (kindly measured for me by Paul Illg, of the United States National Museum), exhibit the condition described and figured by C. B. Wilson (1935a, p. 597) in which “the caudal rami are as long as the entire body behind the carapace.” Carapace similar to that of female except that the medial posterior edge is somewhat curved. Free thoracic segment little more than twice as wide as long; posterior part considerably widened at midline, with long, stiff marginal hairs. Genital segment with sides slightly rounded, set with conspicuous spinules, both marginally and on dorsal and ventral surfaces; four- fifths as wide as long; posterior corners produced dorsally, well rounded ventrally. Basal segment of abdomen distinctly set off; 252 PROCEEDINGS OF THE. NATIONAL MUSEUM VOL. 102 anal segment not demarcated by discernible transverse grooving either dorsally or ventrally in specimens examined, but with a pair of raised longitudinal dorsal ridges as in female, particularly noticeable in stained specimens. Both ventral and dorsal surfaces covered with scattered spinules. Caudal rami slightly less than one-third longer than the abdomen, flattened laterally as in female, with proximal dorsal ridges, inside margins with long hairs, outside with spinules. Second antenna (pl. 14, fig. 10) reduced in size but very stout; basal segment unarmed, strongly united to ventral face of carapace (this segment is apparently omitted in C. B. Wilson’s illustration, 1935a) ; second segment stout and well rounded, projecting upward, armed below with a broad but rather short spine, and a comparatively large, 2-layered, fringed lamina placed distad to the spine. Third seg- ment with a stalked spine, segmented near its tip, and a stalked seta at the base of the claw. Claw short, but very strongly curved, with a rounded projection at its inner base. (The illustration of this ap- pendage, pl. 14, fig. 10, is a flattened, semidiagrammatic view, turned so as to include detail of all the armature.) Lateral prehensile hooks scarcely larger than those of female, but much more strongly curved, papillary setae unbranched. Anterior accessory process like that of female, but comparatively smaller. In- ner piece of first maxilla (pl. 12, fig. 12) bifurcate at tip, inner branch the longer; basal portion of the outer piece broad, extended distally into a long spine as in female; setae of papilla unequal (pl. 12, fig. 15). Maxilla 2 as in female. Maxilliped (pl. 14, fig. 11) about twice the length of the second antenna, with a stout claw bearing a stalked seta; basal segment with a short, rounded process whose tip is more or less demarcated by a roughened area. Posterior accessory process behind maxilliped a stout triangular spine like that of female. Chitin rod between legs 1 and 2 also resembling that of female. Legs 1-3 with setal formula and laminae like female. Basal seg- ment of leg 4 (pl. 12, fig. 19) armed marginally with spinules; more spinules scattered over the upper part of the dorsal surface, and the lower part with a patch of long, stiff hairs running crosswise. The large spines of segments 2-4 more slender and comparatively longer than those of female; all having toothed margins, that of the longest terminal spine with the proximal teeth enlarged on the inner margin. Length of the shorter inner spine not known, as it is unfortunately broken off in all the specimens, including the allotype. DEVELOPMENT Sraces: Two female chalimi, not mentioned by C. B. Wilson in his report, are present in the Galapagos collection. In the following descriptions, they are referred to as Stages a and 6. Stace @ (pl. 12, fig. 2): Total length, 4.2 mm. All the first three thoracic segments incorporated in the carapace, which is as wide as long. Frontal plates indistinct. Free thoracic segment only slightly COPEPOD GENUS PUPULINA (CALIGOIDA)—WILSON 253 wider than long, with small distal lobes; fourth legs attached near the middle of the segment. Genital segment separate from abdomen, widened anteriorly, narrowed posteriorly, with cuticular lobes on the sides at the midpoint; behind these, another pair of lobes that repre- sent the beginnings of the posterior processes. Ventrally, these latter lobes carry the rudiments of leg 5, consisting of a small, rounded flap hardly differentiated from the surface and bearing terminally two short plumose setae; leg 6 not discernible in this specimen. Abdo- men and caudal rami together only a little longer than the genital segment. Abdomen showing no segmentation. Caudal rami flat- tened dorsoventrally, with the plumose terminal setae longer than in the adult. Ventrally, the fore part of the body showing the distinguishing characters of the species already developed. The outer piece of the first maxilla well extended distally; both anterior and posterior ven- tral accessory processes large and of distinctive shape, the posterior process more membranous than in the adult, with the distal attenuated point sharper. A pair of spinous processes between legs 1 and 2, the connecting rod between them scarcely discernible. The second antenna segmented like that of the adult, but more slender, the terminal claw very strongly bent as in adult; prehensile lateral hook comparatively shorter. The second maxilla not at all strongly developed, the basal segment being shortened and not ex- tending outward beyond the maxilliped as in the adult; the terminal claws (pl. 12, fig. 2, a@) not demarcated basally from the apex, the posterior claw very short, broad and dentate. Leg 1 with both rami 2-segmented and all setae present, the branch- ing of the modified spine of the exopod incomplete. Rami of legs 2 and 3 only 2-segmented, the laminae not developed. Leg 4 rela- tively small, consisting of the basal and two other smaller segments. Srace 6 (pl. 12, fig. 13): Total length about 9.3 mm. Metasome a little longer than urosome. Carapace slightly longer than wide. Fourth legs attached near the distal end of free segment, the widened area behind having disappeared; distal edges of segment somewhat angular. Genital segment with processes reaching to about the proximal third of abdomen; rudiments of leg 5 on the ventral side having three setae, one lateral, two terminal, all shorter than the two setae of the preceding stage. Rudiments of leg 6, consisting of a very much ab- breviated lobe and a single seta, located outside and slightly anterior to leg 5. Abdomen 2-segmented dorsally, the short basal segment of the adult indistinctly demarcated ventrally; the anal segment distally with a pair of dorsal longitudinal lines, undoubtedly the beginnings of 967612522 254 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 the prominent ridges of the adult. Caudal rami a little shorter than the abdomen, terminal setae shorter than in Stage a. All appendages considerably larger and more chitinized than in Stage a. Outer piece of maxilla 1 a more slender spine than in adult; claws of second maxilla longer, but of same general shape as in Stage a. Rod between legs 1 and 2 well developed. All legs with rami completely segmented; leg 4, however, not large, and its spines weak and flattened. This chalimus is almost as long as Bere’s specimen from the Gulf of Mexico which, however, is as completely developed as the adult. Hosts and distribution —Manta sp., Atlantic Ocean, near the Azores (van Beneden) ; Manta birostris (Walbaum), Pacific Ocean, near the Galapagos Islands (C. B. Wilson) ; “probably” Mobula hypostoma (Bancroft), Gulf of Mexico, in Lemon Bay, Fla. (Bere). Remarks.—The identification of these Pacific and Gulf of Mexico specimens with the female of the type species from the Atlantic would seem from a comparison with van Beneden’s original descrip- tion and illustrations to be correct. His drawing of the female shows the same general shape of the various parts of the body, and the dorsal design on the genital segment is closely similar, the midinvagination of the posterior margin being characteristic of the species. His illus- tration differs in that the anterior lobe of this design is considerably narrower and the sides longer. In his figure, also, the posterior inside margins of the genital segment are more rounded with the corners less produced, and the abdomen is unsegmented and longer in pro- portion to the genital segment. The only illustrations van Beneden gave of the appendages are some very incomplete figures of those of the cephalic area. These, however, show two important characteristics of the species: The ex- tension of the outer portion of the first maxilla into a slender spine, and the triangular shape of the posterior ventral accessory processes. As these are distinctive features of the Pacific and Gulf of Mexico specimens it seems reasonable to assume that they are identical with those of van Beneden. The form described by van Beneden as the male of Pupulina flores has been stated by C. B. Wilson (1985a, 1935b) to be an immature female of Paralebion elongatus C. B. Wilson.

Description —FrMatp (pl. 18, fig. 1): Gulf of Mexico specimens: Total length, 6.8—7.0 mm.; average length and width of carapace, 3.2 mm. California specimens: Total length 5.9 mm.; length and width of carapace, 2.5 mm. Anterior and posterior margins of carapace curved; sides slightly rounded. Median sinus a small rounded pit; posterior sinuses rather shallow. Distal edges of lateral area set thickly with long hairs, edge of thoracic area with a few spinules. Main lines of dorsal grooving well defined, that of central cephalic area not distinct in available specimens.

Design on dorsal surface of genital segment with rounded peak at top, and single lobes at side and bottom; this pattern identical in the two lots of specimens. Ovisacs reaching slightly beyond end of caudal rami in all specimens. Abdomen slender, indistinctly 3-segmented; a dorsal inflation of the anterior portion of the proximal part the only indication of its division into two joints; this basal portion almost twice the length of the anal segment; both set with marginal spinules, dorsal surface with long slender atest Caudal rami slender, a little longer than bbdomen: attached to the anal segment laterally, and divergent from 256 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 one another; inner and outer margins set with very short, scattered spinules. End of rami bearing terminally a short, broad, spiniform seta and three longer, nonplumose setae, one lateral and one short ventral seta. Second antenna (pl. 13, fig. 3) with spinous process of basal seg- ment well developed; third segment more or less distinct; terminal claw comparatively weak and little curved, with a slender seta at its base. Prehensile lateral hook (pl. 13, fig. 4) short, with broadened base, not strongly curved; setae of papillae branched (pl. 18, fig. 4, a). Mouth tube as described for the genus, well developed and seeming large in proportion to the comparatively small size of the copepod.

COPEPOD GENUS PUPULINA (CALIGOIDA)—-WILSON 25% Mater: Gulf of Mexico specimens: Total length, 5.7-6.1 mm.; width of carapace, 2.2-2.5 mm.; length of carapace, 2.3-2.8 mm. California specimens: Total length, 4.8 mm.; width of carapace, 2.0 mm.; length of carapace, 2.1 mm. Carapace suborbicular, longer than wide; posterior sinuses shallow; thoracic area somewhat elongated and narrowed behind the sinuses. Pattern of cephalic area not distinct in specimens available, except for two anterior ridges, between which are a pair of rather stout spines; another pair of spines located a short distance posterior to the eyes; these spines apparently easily broken off, as in no single specimen are they all intact. Free segment about two and one-half times wider than long, with long dorsal hairs posteriorly. Distal corners of genital segment hardly produced. Abdomen about as long as genital segment, 2-segmented, set marginally and dorsally with fine spinules. Caudal rami one-fourth longer than abdomen, attached laterally as in female, but not divergent; not twisted and flattened laterally to such an extent as those of P. flores, but with similar long hairs inside. Caudal setae as in female. Prehensile lateral hook hardly stouter than that of female, setae of papillae unbranched. Second antenna (pl. 13, fig. 15) compara- tively stout; basal segment well differentiated from ventral surface, second segment armed with a large, ridged lamina and a stout spine; the third with a 2-layered lamina, a spine and a seta, both of which arise from large stalks; claw short but strongly curved. First maxilla (pl. 13, fig. 10) with inner piece elongated distally as in female, but bearing at outer distal third a stout recurved spine; basal outer piece with distal outer lobe larger than in female and extended slightly beyond the curved basal part of the inner piece; papilla (pl. 13, fig. 12) with the three usual setae, the medial being very slender. Maxilliped (pl. 13, fig. 14) with stout terminal claw, armed with a seta on a long stalk; basal segment having a prominent process similar to that of P. flores, but more elongated. Anterior ventral accessory process with smaller spine than in the female; posterior process like that of female. Rod between legs 1 and 2 with posterior, upwardly directed lobes, apparently unarmed. Legs 1-3 like female; leg 4 (pl. 18, fig. 16) like female except that in addition to scattered spines, the basal segment is set dorsally with very long slender hairs. Color.—MacGinitie (1947) has recorded the following notes on the color of the California specimens: “The smaller of the two new species of copepods had a wine-colored eyespot. The body and tail were trans- parent, with wine and blue lines and patches over the body. The 258 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 eggs were salmon colored.” Bere (1986) referred to the “smaller females” (Gulf of Mexico specimens) which are here designated as belonging to this species, as having the carapace “creamy with much branched reddish purple pigment spots; genital segment and egg strings rose colored; eyes black.” Remarks.—The only noticeable differences between the Gulf of Mexico specimens and those from the Pacific are in the larger size of the former and in the thicker integument of the latter. It is interesting to note that this species occurred in both collections with another species of the genus, in the Gulf of Mexico with Pupulina flores and in the Pacific with the other new species herein described. The name minor refers to the notably small size of this species, com- pared with that of the other known species.

Caudal rami about one-fourth as broad as long; differing from those of other females of the genus in being somewhat flattened, very short and broad ; equaling only a little more than a fourth of the total length of the abdominal segments; slightly less than twice the length of the anal segment ; tipped with three very short setae. First antenna with fewer plumose setae on the basal segment than in P. flores, armed terminally as in plate 14, figure 7. Second antenna (pl. 15, fig. 1) with a stout basal spinous process, terminal claw ex- ceptionally long, armed proximally with a stalked spine and a long seta.

Legs 1-3 of the usual form for the genus. Leg 1 (pl. 15, fig. 14) with endopod reaching to distal end of first exopod seoment; etd spine and seta of exopod 2 as in plate 15, figure 15. Leg 2 (pl. 15, fig. 12) with the outer spine of first exopod segment reaching to the svisannl third of segment 3; that of segment 2 reach- ing a little beyond the middle of the third segment. First spine of third segment curved downward, shorter than the second, which is setiform and sparsely plumose. Laminae of endopod with somewhat straight outer edges. Exopod of leg 3 with outer spine of segment 2 reaching to about middle of third segment; outer spines of segment 3 (pl. 15, fig. 16) all very short, subequal; differing from flores and mznor in the pres- ence of a fifth plumose seta inside, this seta shorter and more slender than the others. Endopod lke that of flores except that the lower part of the lamellar expansion of segment 2 is much larger, extending distally almost to the end of the third segment. Leg 4 (pl. 15, fig. 17) with the basal segment comparatively narrow, set with short spines posteriorly. Segments 2-4 bearing short spin- ules inside, that of segment 4 the longest, placed just below the middle of the segment; this latter spinule apparently homologous to the im- perfectly separated cuticular process of the other two species. Second segment with an irregular double row of outer marginal spinelets; segments 5 and 4 with narrow marginal laminae. Major spines of all segments stout and comparatively short, the longest of the terminal spines being only a little longer than its segment.

Antenna 2 (pl. 14, fig. 6) with a cuticular process on basal segment; a stout, curved spine and small laminate process on segment 2; a 4-jointed, broadly stalked seta on segment 3; terminal claw stout and strongly curved, though relatively short, the seta at its base long and 2-jointed. First maxilla (pl. 15, fig. 9) having the basal outside portion of the outer piece widened transversely with a slight distal extension inside; papilla (pl. 15, fig. 10) of two parts, the upper with a very short spine, the lower with two subequal setae, the outer seta very broad and set on a stout basal stalk; inner piece slender throughout, having at its distal outer third a very small curved spine. Maxilliped (pl. 15, fig. 18) with a small lamina at the middle of the basal segment, and an unusual clawlike process with a divided tip, attached basally. Leg 4 (pl. 15, fig. 18) with broad basal segment set with stout spin- ules and long coarse hairs. Segments 2-4 with inside spines and outer marginal laminae as in female; apex of segment 4 not so squarely truncated, terminal inside spine slender and curved, comparatively longer than that of the female. DEVELOPMENT SraceEs: Three development stages of the female are represented in the collection. None is so immature as the earliest stage (a) described for Pupulina flores. The youngest, however, cor- responds very closely to stage b of P. flores, and so is likewise des- ignated as stage 6. Stage c is probably the one immediately follow- ing this in natural development. Other forms designated as young females are considered to represent early growth stages of the adult copepod. No filament was ascertained to have been present in any of the speci- mens, but there is a small ventral structure that is interpreted as being a filament gland. Stace 6 (pl. 14, fig. 4) : Two specimens, to one of which a male is attached to the dorsal neck of the genital segment, clinging by means of the claws of its second antennae. Total length, 7.8 mm.; cephalothorax, 5.5 mm.; posterior part of body, including caudal rami, 2.3 mm. All the first three thoracic segments incorporated in the carapace, which is a little longer than wide; frontal plates distinct. Processes of genital segment reaching almost to the end of abdo- men. Abdomen 2-segmented, the anal segment not being differen- tiated. Caudal rami having the short, broad form characteristic of the species; in this stage they are almost as long as the abdomen. All of the appendages completely segmented, but not so strongly developed as those of the adults. The inner piece of the first maxilla 262 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 not reaching beyond the tip of the anterior ventral process; maxillae and maxilliped crowded together as in adult. Claws of second maxilla short and weak, as noted for immature forms of P. flores. Anterior ventral accessory processes very small spines; the membranous flap of the posterior process hardly separated from the tissue of the ventral face, but the outline discernible. Legs 1-8 completely segmented, with the laminae also well devel- oped. Leg 4 with all the segments indicated, but very short, the whole structure appearing thin; all the spines, including the inside marginal ones, present but very short and weak. Rudiment of leg 5, a lobe hardly differentiated from the surface and bearing three short setae, present ventrally on the proximal surface of the genital process near the outer edge (pl. 14, fig. 4, a) ; leg 6, represented by a single seta at- tached to a minute lobe, located anterior to the fifth pair, the seta projecting beyond the margin of the genital segment. This form is closely similar to that described as stage } for P. flores, and undoubtedly represents the same period in development. ‘That it can properly be interpreted as a chalimus stage, though a very late one, can be seen not only from the shape and size of the genital segment and abdomen, but by the incompleteness of segmentation of the latter. The appendages, though completely segmented, are thin and weak, and the claws of the second maxillae have not assumed the adult form. In addition, legs 5 and 6 are at the height of their development, re- quiring passage through another stage before disappearing. Srace e (pl. 14, fig. 5) : One specimen, male attached. Total length, i1.0 mm.; cephalothorax, 6.5 mm.; posterior part of body, including caudal rami, 4.5 mm.; width of carapace, 6.5 mm. Genital processes only slightly longer than in stage 6, but abdomen considerably longer, showing division into three segments. All appendages more strongly developed than in preceding stage. Distal extension of inner piece of first maxilla reaching well beyond the tip of the anterior ventral process. Claws of maxilla 2 as in the adult. Spines of leg 4 considerably longer and thicker. Ventral ac- cessory processes as in stage 6. Legs 5 and 6 still present, but the setae much shorter than in preceding stage. Whether this stage is to be interpreted as a chalimus or a growth form of the adult is not clear. Although the appendages are more strongly developed than in Stage d, they are still thin and weak com- pared to the young or adult female. In addition to the comparatively short abdomen and the small genital segment, there are still present the rudiments of legs 5 and 6. Youne FEMALE (pl. 14, fig. 2): Three females, measuring between 13.1 and 13.5 mm., show differences in the length of the processes of the genital segment: Slightly shorter than the anal segment (as fig- COPEPOD GENUS PUPULINA (CALIGOIDA)—WILSON 263 ured) ; slightly shorter than the caudal rami; as long as the caudal rami. These must represent different growth stages of the mature copepod; they differ from the adult only in their lesser length, in hav- ing the anterior and posterior parts of the body approximately equal in length, the carapace not so wide, and in very slight differences in the dorsal pattern of the genital segment. Color—MacGinitie (1947) has recevded this species as being trans- parent and without colored markings; eyespot black. Remarks.—MacGinitie has further noted that this species was para- sitized by a trematode, the egg cases being attached mainly to the ab- dominal area. It may or may not be of significance that the right caudal ramus of the holotype female, which is a little shorter than the left, and the left genital process of the paratype female, which is a little shorter than the right, are each much more heavily infested by the trematode egg cases than any other area. The name brevicauda refers to the very shortened caudal rami, particularly conspicuous in the female, though it is to be noted that those of the male are comparatively much shorter than those of other species.

CiarKk THE ECHINODERMS from the Marshall Islands recorded in this re- port were collected during Operation Crossroads by the Oceano- graphic Section of Joint Task Force One under the direction of Commander Roger Revelle in 1946, and by the Bikini Scientific Re- survey under the direction of Capt. Christian L. Engleman in 1947. The number of species of echinoderms, exclusive of holothurians, in these two collections is 80, represented by 2,674 specimens. Although many of these have not previously been recorded from these islands, a number known from the group were not found, while others that certainly occur there still remain undiscovered. Of the 80 species collected, 22 were found only in 1946 and 24 only in 1947; only 34, about 40 percent, were found in both years. It is therefore impossible to appraise the effects, if any, of the explosion of the atomic bombs. But the specimens of the 54 species collected in 1947 are all quite normal. On the basis of the scanty and inadequate data available it would seem that the bombs had no appreciable effect on the echinoderms. Some of the species are represented by young individuals only. This is always the case in any survey of the echinoderm fauna of any tropical region. A few localities are found to yield nothing but young individuals of certain species at a given time, or possibly unless collections are made over a series of years. A few of the records are from depths greater than any heretofore recorded for the species. These records are based mostly on dead material, which may have washed down from the shallower water of the reefs, though there is no reason to believe that the animals could not have lived at the depths given. 265 967608—52 1 266 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 The echinoderms represented in the collections, with the year or years in which they were found, are listed on page 299. Subsequent to the completion of this report some specimens collected in 1948 have come to hand. They have been noted in the text under Localities, and for convenience they have been included with the entries for 1947 in the list just mentioned. This collection, unusually extensive for any region in the Poly- nesian area, was assembled by 16 members of the expeditions, none of whom had a special interest in the echinoderms. These were: Capt. R. H. Draeger, M. C., U. S. Navy; Lt. Comdr. Fred C. Ziesen- henne, U. S. N. R.; Capt. Earl S. Herald, U. S. Army; and Frederick M. Bayer; Vernon E. Brock; Frank Cali; Martin W. Johnson; Thomas F. Kohler; Harry S. Ladd; Joseph P. E. Morrison; R. Dana Russell; Leonard P. Schultz; William Randolph Taylor; Joshua R. Tracey; Douglas M. Whitaker; and Fred C. Zimmerman. It is a pleasure to thank these gentlemen and to congratulate them on the notable contribution they have made to our knowledge of the echino- derms of Polynesia.

A perfectly clean subambital spine, U.S.N.M. No. E. 7372. Notes.—This spine agrees fairly well with some of the subambital 268 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 spines in a specimen of Chondrocidaris gigantea at hand from the Hawaiian Islands, and I have little hesitation in referring it to that species. It is 87 mm. long and 4 mm. thick without the winglike processes. The wings are in seven rows along the lateral and aboral side of the spine, those of one row alternating with those of the rows on either side. The adoral side of the spine is flattened and is with- out processes. The processes begin 3 mm. from the base. There are three or four in each row. Those nearest the base are high conical tubercles. From the base outward they become progressively elon- gated and flattened, the outermost being high thin ridges 4-6 mm. long with a slightly convex crest. The terminal 7-12 mm. on the spine carries five high thin ridges about 2 mm. high, highest at the proximal end, thence curving downward to the apex. The color is white with streaks and spots of ight pink. The spine resembles in a general way that from Lau, Fiji, figured by Dr. H. L. Clark under the name of Chondrocidaris problepteryx (Bernice P. Bishop Mus. Bull. 181, p. 314, pl. 41, fig. EK, 1945), but the wings are more numerous, are not truncated distally, and are continued downward to the base.

The fact that the detached spines of this species and of Chondro- cidaris gigantea and E'ucidaris metularia were dredged in deep water does not necessarily indicate that the individuals from which these spines came lived at these depths. Although this condition is pos- sible, it is more likely that they lived in shallower water and that after their death the spines were washed into the localities in which they were found.

One very young specimen, U.S.N.M. No. E. 7506. Notes.—The very small specimen (E. 7506) bears little resemblance to the adult, but instead suggests a small slender spined “’chinometra. It is slightly oval, two-thirds as broad as long, and twice as long as high, with the aboral surface gently convex. It measures 7 mm. in length, 5.5 mm. in width, and 3.5 mm. in height. The genitals are fused into a somewhat irregular five-sided plate 1.5 mm. long and 1 mm. broad. The posterior genital appears to be much larger than the others and bears a large perforated tubercle surrounded by a broad areole. Numerous other tubercles about half as large are scattered over the surface of the combined genitals. There are four large madreporic pores, each on the summit of a short tube, the four tubes crowded into a square with rounded angles and slight notches on the sides. No pores are visible in the genital plates. The triangular oculars are very small, each situated on one of the sides of the combined genitals. There are from 10 to 12 large interambulacrals in each column. These are at first hexagonal, toward the ambitus gradually becoming transversely elongated, and at the ambitus about twice as broad as long; below the ambitus they gradually become shorter again. Aborally each interambulacral plate bears a large central perforated tubercle surrounded by a broad areole margined by a circlet of small and glassy, usually contiguous, tubercles. On the broad interambu- lacral plates at and below the ambitus there are commonly two tu- bercles to a plate. The ambulacrals are at first minute. After a series varying from 12 to 19, much larger ones, each with a large central tubercle, appear, and soon all are large with usually three pores in a slightly curved line along the outer border. At the ambitus the ambulacrals are hexagonal and about as high as the much broader interambulacrals, with central tubercles about as broad as those of the latter. On the aboral surface the very small ambulacrals always extend farther down on one side of the ambulacral areas than on the other. There is a single glassy spheridium situated in a deep and capacious pit at the adoral end of each ambulacrum. The peristome is circular, 2 mm. in diameter, densely and evenly covered with very minute spinous plates. The mouth is closed and no teeth are visible. The periproct is large, situated just below the ambitus and sloping slightly inward, diamond shaped with rounded angles, transversely elongated, 2.3 mm. wide and 1.4 mm. high. Most of its surface is covered by three large plates of which the two outer reach halfway 967608—52—-3 282 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 from the lateral apices to the anterior angle. The remaining area, from the anterior angle about halfway to the posterior, and halfway to the lateral apices, is covered by several much smaller plates. The primary spines are 2 mm. long, cylindrical or slightly tapering, with eight high and rounded longitudinal ridges. In section they resemble the spine of Lchinolampas alexandri var. sibogae figured by Mortensen (Monograph of the Echinoidea, vol. 4, part 1, p. 281, fig. 272, c. 1948). The secondary spines are very fine, 0.7 mm. long and cylindrical. The ophicephalous pedicellariae resemble the one from £’. a. sibogae figured by Mortensen (pl. 14, figs. 5, 6). The color is light olive-green. The test is yellowish white with some olive-green patches and a purple patch on the genitals. This little specimen bears a close resemblance to the young E'chino- lampas depressa figured by Agassiz (Revision of the Echini, pl. 16, figs. 1, 2, 8, 1872), but it is much lower than is shown in figure 3, in lateral view being more like the larger specimen shown in figure 10. The periproctal structure is as shown in figure 14, but the three large plates are smaller. Dr. Morrison’s specimen (E. 7278) is 77 mm. long, 69 mm. in maxi- mum width, 35 mm. high at the apical system, and 86 mm. high at the posterior end. It agrees wel] with a specimen from Tavoy figured and described by Koehler, but is slightly larger and more depressed. Dr. Schultz’s specimen (E. 7279) agrees with the preceding, but is somewhat smaller. This species has heretofore been reported only from Mauritius, Ceylon, and the Bay of Bengal.

Locality —Bikini Atoll; off Bikini Island; 400-450 feet; Russell, August 14, 1947. One specimen, U.S.N.M. No. E. 7365. Notes —R=45 mm., r=18 mm.; R=2.4 r. This specimen agrees fairly well with Déderlein’s type specimen, which was dredged by the Siboga in the Solor Strait near Flores in 113 meters, though it is rather more than twice as large. The plates of the disk agree with those of the type. The innermost spines of the carinal row are 6 mm. high, those following decreasing rapidly in height and disappearing at the level of the third superomarginal. The plates of the disk, ex- cept for those of the two rows adjoining the superomarginals, each have a prominent central tubercle. There are no pedicellariae. There are eight superomarginals of which the outer five are in con- tact in the midradial line. The two interradial superomarginals each bear a prominent spine 2 mm. high on the inner edge, a shorter spine or tubercle in the middle, and usually one or two tubercles near the outer edge. The next two superomarginals on each side bear similar but smaller spines. The following superomarginals bear usually two or three tubercles near the inner edge, one in the middle, and from one to three near the lower edge. The inferomarginals bear a group of from two to four tubercles near the upper edge, or sometimes a group of three long spines. Each actinal plate bears a short stout spine. The adambulacral plates bear two large stout spines on the outer surface and a comb of usually seven subequal furrow spines. The slight differences between this specimen and the type, the only other specimen known, are probably due chiefly to size and age.

Genus OPHIODERA Verrill OPHIODERA PUNCTATA, new species Description.—The disk is stellate with evenly rounded interbrachial borders (dried), and is 27 mm. in diameter; the arms are 160 mm. long. The disk is thickly studded with minute oval concretions uniformly distributed over the surface but becoming smaller toward the inter- radial borders; these do not extend out onto the arms, though there may be a few just beyond the ends of the radial shields. The disk thus resembles that of Ophiomywxa bengalensis Koehler, but the concretions are smaller and end abruptly at the arm bases. The radial shields are conspicuous, 5 mm. long and about 1.5 mm. broad. Their distal ends are connected across the arm bases by a row of six small rounded contiguous plates. There are no upper arm plates, but there are a few scattered rounded plates on the aboral side of the first two arm segments. The interbrachial areas below are naked. The genital slits are long, reaching nearly to the sixth spine-bearing side arm plates. Parallel to the genital slits and near them is a row of eight or nine short black lines at right angles to the slits, the outermost about 2 mm. long and 292 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 the following regularly decreasing in length to that just beyond the oral shield, which is merely a dot. The oral shields are reniform, nearly twice as broad as long. The adoral shields are broad, outwardly adjoining the first under arm plates; they do not quite meet beneath the oral shields. The jaw plates are narrow with parallel sides, so that there is a long triangle of membrane between them. There are four mouth papillae. The outer- most is narrow, conical, and sharply pointed. The next is conical, but stouter. The third is broader with almost or quite parallel sides and a broad chisellike tip. The innermost is broadly fan shaped with a curved and finely serrate outer edge and resembles the teeth. The under arm plates are large and well developed with a sharp angle proximally and a deep distal notch; at the arm bases they are almost in contact; distally they become narrower and somewhat more separated, and the distal notch becomes deeper. At the arm tips they are small and widely separated, the side arm plates almost meeting between them. The side arm plates beyond the disk bear four, rarely five, subequal spines of which the uppermost is slightly longer and considerably stouter than the others, and the two lowest are the most slender. Toward the arm tips the number of spines becomes reduced to three, and the upper transforms into a stout hook with three or four teeth. Later the middle spine also becomes hooklike. At the end of the arms there are only two spines, both in the form of hooks. The disk is rather dark brown with numerous white specks and conspicuous dull yellow radial shields. The arms and the oral surface are brownish yellow, with a conspicuous row of short black lines along the genital slits. Locality —Bikini Atoll; off Enyu Pass, 700-725 feet; August 22, 1947.

The general structure is similar to that of O. clippertoni, but there are only three arm spines—four on the first three or four side arm plates beyond the disk—and the uppermost arm spine is from half again to twice as long as the others, slender and tapering gradually to a sharp tip; near the arm bases it may be considerably longer than an arm segment. The middle spine is shorter, but usually stouter. The lowest spine is about as long as the middle spine, and usually somewhat more slender. The disk is light brown, the spinules white. The upper arm plates are light brown with a narrow white border and a narrow white curved band extending across the plates from the spines on one side to those on the other. The under arm plates are light brown with a narrow distal white border. The oral and adoral shields have a dark center and broad white borders. In two of the specimens all six arms are of the same size. In the remainder, three of the arms are much smaller than the others, in- dicating autotomous division. Locality Bikini Atoll; in the lagoon; Morrison, August 26, 1947. Four specimens, U.S.N.M. Nos. E. 7359 (type), E. 7360. 298 PROCEEDINGS OF THE NATIONAL MUSEUM VOL, 102 Notes.—In spite of the close agreement in the form of the arm plates and the plates of the oral surface, and in the number of arms, with the species of Ophiocomella, this little species should be referred to Ophiomastixz, with which it agrees in the relations of its arm spines and in the general scheme of its color pattern. It does not agree with any of the known species of Ophiomastia, none of which are six-rayed in any stage. The color pattern also is unique.

ADDITIONAL RECORDS OF ECHINODERMS FROM THE MARSHALL ISLANDS From time to time scattered references to specimens from the Mar- shall Islands have appeared in the literature, based upon material that has found its way into museums from various sources, much of it from the Reverend B. G. Snow, a resident missionary. Most of the specimens are from Ebon (Boston Island), with some from Jaluit (Bonham Island), both in the extreme south of the Marshall group. The only systematic collecting that has been done in the Marshalls was by the Swedish expedition to the South Sea Islands under the leadership of Dr. Sixten Bock in 1917. A report on the Ophiuroidea of this collection was published by Prof. René Koehler in 1927 (Géteborgs Kungl. Vet. Vitt. sam. Handl., vol. 33, No. 3), which lists 16 species, mostly from Jaluit and Ebon, of which the following are not represented in the present collection. Ophiomyxa brevispina von Martens (Jaluit) Amphilimna serradiata (Duncan) (Jaluit) Ophionereis porrecta Lyman (Ebon) Ophiothrix demessa Lyman (Jaluit) Ophiothrix galatheae Ltitken (Jaluit) Ophiothrix triloba von Martens (Jaluit) Ophiopezella dubiosa de Loriol (Jaluit) It is probable that Professor Koehler’s Ophiothrix galatheae is the same as O. longipeda of the present list. The Crinoidea of this expedition, all collected by Dr. Chr. Hessle, were described by Professor Torsten Gislén in 1940 (Kungl. Svenska Vetenskapsakademiens Handlingar, ser. 3, vol. 18, No. 10). He re- MARSHALL ISLANDS ECHINODERMS—CLARK 303 corded five species of which four are not represented in the present collection. These are: Eudiocrinus tenuissimus Gislén (Jaluit) Lamprometra palmata (J. Miiller) (Ebon; Jaluit) Cenometra bella var. magnifica Gislén (Jaluit) Dorometra nana (Hartlaub) (Ebon; Jaluit) Earlier records of crinoids from the Marshall Islands are Stephano- metra protectus from Ebon, collected by the Reverend B. G. Snow in 1877 (A. H. Clark, Bull. Mus. Comp. Zool., vol. 51, p. 242, 1908, as Himerometra heliaster), recorded also by Gislén and represented in the present collection; and Lamprometra palmata, also collected by Mr. Snow at the same time (Hartlaub, Mem. Mus. Comp. Zool., vol. 27, No. 4, p. 409, 1912, as Antedon brevicuneata). Dr. Hubert Lyman Clark in 1915 (Mem. Mus. Comp. Zool., vol. 25, No. 4, p. 343, No. 13868) recorded Ophiolepis superba from Ebon, where it had been collected by Mr. Snow in 1877. It has not since been reported from the Marshall Islands. Additional species known from Johnston Island (A. H. Clark, Bernice P. Bishop Mus. Bull. 195, p. 119, 1949) are: Ychinostrephus aciculatus, EF’. molaris, Brissus latecarinatus, Culcita novae-guineae forma novae-guineae, Acanthaster planci, Mithrodia fisheri, and Ophiactis savignyit.

Wetp TWENTY-FOUR new species of cynipids and their galls and two inquilines are described herein, together with some notes on biology and synonymy. One new generic name is proposed for three described gall-making species from the Pacific coast. Types of the new species are in the United States National Museum (U.S.N.M.). Paratypes are deposited in institutions that are indi- cated by the following abbreviations: the American Museum of Natural History (A.M.N.H.), the Chicago Museum of Natural His- tory (C.M.N.H.), the Academy of Natural Sciences of Philadelphia (A.N.S.P.), the California Academy of Sciences (C.A.S.), the Museum of Comparative Zoology (M.C.Z), Cornell University (C.U.), the Hlinois Natural History Survey (1I.N.H.S.), and the University of Utah Museum (U.U.M.). Genus SAPHONECRUS Dalla Torre and Kieffer SAPHONECRUS BREVICORNIS (Ashmead), new combination Synergus brevicornis ASHMEAD, Trans. Amer, Ent. Soc., vol. 23, p. 189, 1896. The types have the radial cell open; hence the species belongs in Saphonecrus. Genus SYNOPHRUS Hartig SYNOPHRUS MEXICANUS (Gillette) Synergus mexicana GILLETTE, Trans. Amer. Ent. Soc., vol. 23, pp. 90, 96, 1896. The type, in the U. S. National Museum, has the petiole smooth and 315 967604—52——1 316 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 the radial cell open; hence the species belongs in Synophrus and was transferred in “Hymenoptera of America North of Mexico,” p. 613, 1951. Genus SYNOPHROMORPHA Ashmead Synophromorpha ASHMEAD, Psyche, vol. 10, p. 45, 1903. Ashmead, in his key to genera, designated Synophromorpha salicis as the type of this genus, but no further description of it was ever published, and no specimen so labeled was found in the Ashmead collection. It was supposed to have been reared from a dipterous gall on willow and considered to be a guest fly. He characterized the genus as having an open radial cell, the petiole not longitudinally striate, and separable from Synophrus Hartig by having a coriaceous instead of transversely sculptured mesoscutum with more or less distinct parapsidal grooves, smaller foveae, incomplete areolet, and the third segment of the antenna longer than the fourth in the male. SYNOPHROMORPHA SYLVESTRIS (Osten Sacken), new combination Synophrus (?) sylvestris OSTEN SACKEN, Ent. Zeit. Stettin, vol. 22, p. 415, 1861. This species agrees with the diagnosis of Synophromorpha and is here transferred to that genus, and as the original spelling is permissi- ble Latin it is retained. It was reared from the gall of Diastrophus nebulosus Osten Sacken on blackberry in the Washington, D. C., area. Adults agreeing with paratypes of this species have often been reared from this gall in this, the type, area and in many other localities, Range in length of females 2.1-3.25 mm. Average of 31 specimens 2.86 mm. Males 1.8-2.65 mm. Average 2.25 mm. Similar adults have been reared from galls of Diplolepis tgnota (Osten Sacken) in the Washington area. Two new species are described in the present paper. Like sylvestris they have the face striate, antennae and legs straw yellow, antennae 12-segmented in the female, mesoscutum broader than long, parapsidal grooves percurrent and broadened posteriorly, foveae smooth, carinae on propodeum straight, diverging above, abdomen with a hairy ring at base and a faint indication of a suture between tergites IT and III as in Ceroptres. SYNOPHROMORPHA TERRICOLA, new species Differs from sylvestris in having the mesopleuron smooth instead of finely aciculate and a fainter coriaceous sculpture on mesoscutum. The parapsidal grooves closely approach each other at scutellum where they are separated only by a distinct median groove. Length of fe- males 2.2-2.9mm. Average of 32 specimens 2.57 mm. Males have 14- AMERICAN CYNIPID GALL WASPS—WELD 317 segmented antennae. Length 1.8-2.7 mm. Average of 20 specimens 2.42 mm. Types —U.S.N.M. No. 60105: Type female, allotype, and six para- types. Paratypes also in A.M.N.H., C.M.N.H., A.N.S.P., C.A.S., and M.C.Z. Habitat—Emerged early in May from galls of Diastrophus radicum Bassett at East Falls Church, Va. Part of the paratypes are from galls of D. bassettii Beutenmueller, from Washington, D. C. SYNOPHROMORPHA RUBI, new species Differs from S. terricola in having the parapsidal grooves widely separated behind with a median groove wanting or a mere notch. Wemales measure 2.2-2.9 mm. Average of 15 specimens 2.46 mm. Males 1.6-2.2 mm. Average of six specimens 1.77 mm. Types.—U.S.N.M. No. 60106: Type female, allotype, and four para- types. Paratypes also in A.M.N.H., C.M.N.H., A.N.S.P., C.A.S., and M.C.Z. Habitat—The types emerged in July from galls of Diastrophus euscutaeformis Osten Sacken collected at Winnetka, III. Genus CEROPTRES Hartig CEROPTRES OBTUSILOBENSIS Weld Diplolepis q.-obtusilobae KarscH, Zeitschr. fiir Ges. Naturw., vol. 58, pp. 292, 298, pl. 6, figs. 3, 8a, 3b, 1880. Cynips obtusilobae DALLA Torre, Catalogus hymenopterorum, vol. 2, p. 47, 1893 (cites Karsch). The Karsch gall in Berlin is an abrupt terminal stem swelling on Quercus stellata, from Texas, labeled Cynips quercus obtusilobae. The three type adults reared from it, which Karsch considered to be the makers of the gall and related to Veroterus, are all guest flies of the genus Ceroptres. Dalla Torre was the first to apply a binomial desig- nation to the species. As obtusilobae was preoccupied in Ceroptres in 1885 by Ashmead (Trans. Amer. Ent. Soc., vol. 12, p. 300) the name obtusilobensis was proposed in the “Hymenoptera of America North of Mexico,” p. 614, 1951, for the Karsch species. Genus LIPOSTHENES Foerster LIPOSTHENES GLECHOMAE (Linnaeus) Cynips glechomae LINNAEUS, Systema naturae, ed. 10, p. 553, 1758. Aulaz latreillei Kierrer, Ent. Zeit. Wien., vol. 17, p. 257, 1898. Linnaeus did not describe his species, but he cited seven references ; six of these refer to galls only. However, in one, Reaumur (Memoirs, 1 See p. 315 for explanation of abbreviations used throughout this paper. 318 PROCEEDINGS OF THE NATIONAL MUSEUM Vou. 102 vol. 8, pp. 460-462, figs. 1-5, 1737) says he reared a brown fly with four wings, similar to those he had reared from oak but with slight and sufficient differences to indicate it is a distinct species. This brief characterization of the maker of the gall validates the name that Linnaeus gave to the species in 1758. He himself evidently had not seen the maker, for in Fauna Suecica, p. 386, No. 1520, 1761, he says of the gall “insectum tamen non dum vidi” (however, I have not yet seen the insect). Kieffer makes two misstatements when he writes (loc. cit.) : “Linné hat zuerst aus den Gallipfeln von Glechoma hederacea den Erzeuger erhalten, und denselben Cynips glechomae genannt; die Beschreibung lautet: ‘fusca thorace villoso.” Fauna Suecica 1761, pag. 386, Nr. 1520.” Reaumur, in France, was the first to rear the maker. The phrase “fusca thorace villoso” does not occur in the reference that Kieffer cites. There is in Geoffroy (Histoire abregée des insectes qui se trouvent aux environs de Paris . . ., vol. 2, p. 203, No. 20, 1762), the statement, “Cynips totus fuscus, thorace subvillosus. Sa coleur est brun et noiratre; son corcelet est un peu velu.” Then, in 1787, Fabricius (Mantissa insectorum . . . , vol. 1, p. 252), in what is merely a key to species in each genus, shortens this to “fusca thorace villoso,” to distinguish glechomae from the preceding species in his key. The sides of the pronotum are pubescent and the mesoscutum is bare. In 1841 Hartig described adults he had from Foerster as having a shining mesonotum and makes the comment that “Cynips glechomae Lin. (fusca thorace villoso) muss notwandig ein andere Insect gewesen sein, da die Brust nichtsweniger als behaart ist.” He does not name it, however. He takes the three Latin words to be a condensed description instead of a mere phrase to separate it from another species. This Hartig-Foerster material is what Foerster in 1869 made the type of his genus Liposthenes. Latreille also (Histoire naturelle générale et particuliére, des crustacés et des insectes . . . , vol. 13, p. 207, 1803) reared the maker and described it as very black, smooth, shining—the same insect that Hartig and Foerster examined. In 1898 Kieffer gave a new name to this species, calling it Awlax latreillei, and in 1910 (Das Tierreich, Lief. 24, p. 668) it appeared as a species distinct from glechomae Linnaeus from Sweden (sic), its gall not distinguishable from that of glechomae. Aulawx latreillei is listed as from Britain, Germany, France, Austria, Italy, and North America. If the above reasoning about the Latin phrase is correct, then Kieffer was not justified in giving a new name to the Hartig-Foerster- Latreille material, and the name Jatrezlec should go into synonymy. There is only one species making the characteristic gall on Nepeta in AMERICAN CYNIPID GALL WASPS—WELD 319 Europe and this species was introduced, together with its host plant, into the eastern United States. It should be known by the specific name that Linnaeus gave toit. Taylor (Amer. Journ. Botany, vol. 36, pp. 222-230, February 1949) published an excellent study of the early stages of this gall. Genus DIPLOLEPIS Geoffroy Rhodites Hartig, 1840, was founded on three species and Foerster in 1869 designated Cynips rosae Linnaeus as the type. The name is transliterated from a Greek word meaning “pertaining to a rose.” Thus the name when applied to an insect implies an association with rose. In both the American and European literature up to 1917 the maker of a rose gall has been placed consistently in Rhodites. Neither Hartig nor Foerster seems to have consulted the old litera- ture. Geoffroy in 1762 (Histoire abregée des insectes, vol. 2, p. 308) proposed the genus Diplolepis for six species of gall makers, which he designated simply by number. Under No. 1 he cites Rosel, ins. vol. 3, suppl., plates 35, 36, and 53, figs. 10, 11, where he describes and figures an insect and gall on the leaf of oak without name. (Fourcroy in 1785 gave the name Diplolepis quercus to Geoffroy’s No. 1.) In the bibliography of his No. 2 he cites among others Systema Naturae, ed. 10, p. 553, No. 1, 1758, which is Cynips rosae Linnaeus. The other numbered species lack a bibliography and have no standing. Thus by a reference the genus is established on one named species, and the definite designation of Cynips rosae as the type by Rohwer and Fagan in 1917 (Proc. U. S. Nat. Mus., vol. 53, p. 365) was unnecessary. They seem to feel that there is some slight doubt about the supposed designation of C. rosae as type by Geoffroy. The genus is monobasic. It is next-to-the-oldest name in the Cyni- pidae and was plainly intended to apply to a gall maker. And yet it does not appear in the key to genera in Foerster (1869), Mayr (1851), or Ashmead (1903), either as a valid name or a synonym. It was used erroneously in 1910 by Dalla Torre and Kieffer in Das Tierreich, Lief. 24, Cynipidae. As Fhodites and Diplolepis are isogenotypic, Rhodites disap- pears in synonymy, although there is sentiment for having it placed on the conservanda list. Kinsey and Ayres (Indiana Uni- versity Studies, vol. 9, Study 53, 1922) were the first to adopt Diplo- lepis in place of Rhodites, and Felt in 1940 (Plant galls and gall makers) followed their example. The name is coming into increased use among American authors. Europeans still use Rhodites. Itisa case of an appropriate name made familiar by a century of usage against the plain intent of an older author. The establishment of a name by a reference is not an unusual or doubtful procedure. Lin- 320 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 naeus thus established his Cynips glechomae. Whether plenary power should be exercised in a case where the obvious intent of an author is so evident and his procedure so little open to question is a matter for discussion.

Similar to the gall of D. rosaefolit Cockerell in the eastern United States. Habitat.—The types are from galls collected at Corvallis, Oreg., on October 16, 1939, along a road northwest of the university campus. Adults emerged June 7-14, 1940. Similar galls were seen at Holland, Siskiyou, and Klamath Falls, Oreg.; Chelan and Waitsburg, Wash., and Walnut Creek, Calif. DIPLOLEPIS TERRIGENA, new species Female.—Head and thorax variegated, red and black, abdomen and legs red. Antennae 14-segmented, three basal segments slightly red- dish. Mesoscutum shining, smooth, with scattered punctures; parap- sidal grooves broad, rugose, percurrent, ending in a rugose area at pronotum, median groove represented posteriorly by confluent punc- tures and continued forward by a dark median line.

Gall (pl. 17, fig. 17) —A large abrupt “root” gall at the crown, up to 50 mm. in diameter, surface somewhat botryoidal. Habitat—The types are from galls collected at Ojai, Calif., on April 6, 1922. They contained pupae at that time. Adults emerged April 26 to May 20. Galls were seen also at St. Helena and Los Gatos, Calif. DIPLOLEPIS POLITA (Ashmead) Rhodites polita ASHMBAD, Colorado Biol. Assoc. Bull. 1, pp. 14, 38, 1890. Rhodites occidentalis BEUTENMUELLER, Brooklyn Ent. Soe., vol. 17, p. 45, 1922 (new synonymy). Ashmead described polita from a gall similar to the eastern Diplo- lepsis bicolor (Harris), found on Rosa californica, but adds the state- ment that he has seen galls from Dakota and Colorado also. As the types in the U. S. National Museum are from Marin County, Calif:, and bear Koebele’s label with No. 70 in red ink, the type locality is California, and the Dakota and Colorado material was misdetermined. There are males of this species in collections from Los Angeles but not marked as types. Fullaway reared adults, which he determined to be Rhodites bicolor (Harris), from Cupertino (Stevens Creek), Calif., and described them in 1911 (Ann. Ent. Soc. Amer., vol. 4, p. 377). In 1922 Beutenmueller gave this bicolor Fullaway the name of Rhoditis occidentalis. The U.S. National Museum has a female specimen from Cupertino (Stev- ens Creek) which must be a type of the Fullaway description. It agrees with types of 2. polita Ashmead. It measures 3.1mm. The 5 mm. measurement in the description must be a misprint for 3 mm. Genus NEUROTERUS Hartig NEUROTERUS TANTULUS, new species Female.—Black.

One paratype was cut out September 5, 1918, from a gall collected at Los Gatos. Another was cut out November 10, 1949, from a gall collected at Idyllwild on No- vember 6, 1948. One (not in the type series and all amber) was cut out dead in 1946 from a gall collected on Mount St. Helena in August 1922. PARACRASPIS, new genus Genoty pe-—Callirhytis quadaloupensis Fullaway. Agamic female.—Head massive, broader than thorax, cheeks broad- ened behind eyes, malar space without groove, antennae 14-segmented, filiform, third longer than fourth, longer than first two. Thorax normally arched; pronotum narrowed to one-ninth in middle. Meso- scutum broader than long, parapsidal grooves complete or incomplete, median wanting. Scutellum rounded behind, with a transverse groove at base, lateral impressions prominent. Mesonotum covered with uni- formly distributed appressed hairs which almost hide the sculpture.

Gall (pl. 16, fig. 4, a2) —A bud gall in June produced from weak lateral buds on previous year’s growth of saplings 1 to 3 feet high, on sprouts from stumps and on lower limbs of small trees, occasionally from dormant buds on main trunk of trees. Jn good light, deep green with white spots at attachment of radiating fibers inside; in deep shade, more or less etiolated. Globular, firm, fleshy, bare, up to 18 mm. in diameter, not deciduous. Wallimm. thick. Central cell rela- tively large, supported by many coarse, branching, radiating fibers. Larval cell 6 mm. by 3.2 mm. and its wall 1.5 mm. thick with big cells at base of the radiating fibers. Exit hole 2.2 mm. in diameter made while gall is still green. After the emergence of the maker the gall turns brown and becomes wrinkled. Many undersized galls are para- sitized. Out of more than 200 galls collected only 20 makers emerged. Habitat—The type series of galls was collected at East Falls Church, Va. June 26, 1948. Adults emerged June 28, 30, July 2, 4, 1948. None of these galls was seen at this place in 1949, in 1950, or in 1951. Galls had been seen at Rosslyn and Lucketts, Va., Washing- ton, D. C., and Lanham, Md. AGAMIC GENERATION ? In early September 1948 approximately 65 bud galls were collected on the ground under a large pin oak tree only a few feet from where galls of A. globus herein described were taken the previous June. Similar galls had not been seen here before—circumstantial evidence that it is the alternating form. It occurs in August and September at AMERICAN CYNIPID GALL WASPS—-WELD Bye the end of the season’s growth. It is smooth, bare, green with small purple spots marking the attachment of numerous radiating fibers within, up to 14 mm. in diameter, rounded at distal end, slightly taper- ing at attached base, the wall relatively thin (.8 mm.) (pl. 16, fig. 4, b). Larval cell ellipsoidal, 6 by 4mm. Galls drop in late August or early September and soon turn brown and become slightly wrinkled. At this time the nutritive layer is all used up and full-grown larvae and pupae are found inside. Some may emerge in the fall but the adults described below were cut out of the galls on October 18 and November 5, 1949. As they are thought to be the alternating agamic generation of globus they are not given a different specific name. Agamie female.—Head and thorax black, abdomen red, tibiae and tarsi brown. Cheeks broadened behind eyes. Antennae 13-seg- mented. Mesoscutum rugose with parallel longitudinal ridges back of anterior lines and short transverse ridges on either side of them; parapsidal grooves shallow, rugose, percurrent, a median streak per- current in the sculpture. Scutellum rugose, without distinct median depression or posterior emargination, foveae with oblique ridges in bottom. Large spot on base of radial cell covers areolet also. A short median carina on propodeum. Abdomen as long as thorax, all tergites normally showing on dorsal curvature, hind margin of IT smooth, rest punctate, VII pubescent. Ventral spine longer than hind metatarsus. Mesonotum ratio 1.5; antenna 2.0; wing 4.0. Length 3.9-4.55 mm. Average of three 4.3 mm. Genus ANDRICUS Hartig ANDRICUS BRUNNEUS Fullaway Andricus brunneus FULLAWAY, Ann. Ent. Soc. Amer., vol. 4, p. 353, 1911. This species was described from a “thin-walled subglobular gall, pointed at both ends and about the size of a pea” on the leaves of Quercus douglasii. It seems to have been associated with the wrong gall. The type gall in the Stanford collection, agreeing with the above description but with a central cell supported by radiating fibers, seems to be a gall of what was described under the name of Andricus atrimentus Kinsey. I have reared adults agreeing with the types from a midrib cluster on this host at Stanford University, the type locality, and also from similar galls on Quercus lobata, Q. dumosa, and Q. garry- ana. These galls are from 3-5 mm. in diameter, in a cluster of 4 to 6 on the under side of the leaf (pl. 17, fig. 16), tan, slightly mottled, slightly pubescent, thick walled without any radiating fibers or free central cell, dropping in September. From galls collected on Quercus douglastvi at Stanford University on October 27, 1948, adults emerged October 18 to November 5, 1949. 328 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 ANDRICUS ALBICOMUS, new species Female.—Red, often with some black on occiput, foveae, propodeum, and parts of abdomen. Head coriaceous; from above vertex bare, cheeks slightly broadened behind eyes, occiput not concave; from in front malar space 0.4 eye, without groove, antennae filiform, 13-seg- mented. Mesoscutum microcoriaceous, shining, longer than broad, with scattered hairs, parapsidal grooves percurrent. Scutellum rugose, pubescent, margined on sides, foveae smooth. Mesopleuron bare, smooth. Wing hyaline, pubescent and ciliate, veins pale and slender, radial cell four times as long as broad, areolet and cubitus almost obsolete. Claws toothed. Abdomen jonger than head plus thorax, almost as high as long, lengths of tergites as 45:18:8:4:4, slightly gibbous below petiole, the curved tip of ovipositor projecting beyond sheaths. Ventral spine longer than hind metatarsus. With width of head as a base, the length of mesonotum ratio is 1.4; antenna 2.9; wing 4.9; ovipositor 5.8. Range in length 1.5-2.4 mm. Average of 53 specimens 2.0 mm. Close to Andricus kingi Bassett, whose disk is smooth back of septum and antennae are 14-segmented. Types.—U.S.N.M. No. 60114: Type and 10 paratypes. Paratypes also in A.M.N.H., C.M.N.H., A.N.S.P., C.A.S., and M.C.Z. Host.—Quercus garryand. Gall (pl. 16, fig. 5)—A thin-walled conical gall about 5 mm. in diameter on the under side of a leaf in the fall, densely covered with pedicelled, stellate grayish-white hairs.

From one to eight on an acorn. Monothalmous. Habitat.—The type locality is Prescott, Ariz. From galls collected in October 1935 by Mrs. N. W. Capron, adults were cut out on Octo- ber 10, 1936, and one emerged April 23, 1937. In July and August 1947 she tied bits of cloth over a lot of affected acorns, so that the galls would not drop to the ground and be lost. Adults were cut out of these galls on March 20, 1948 and January 7, 1949. More were bagged in the summer of 1948, when the galls began to drop by the middle of August, a month earlier than usual, perhaps owing to a dry season. Many of these were blanks. Adults emerged April 15, 23, 26, 30, 1949. ANDRICUS PILULA Bassett This species was described from two females cut from galls from southern Utah. The types have the claws toothed, not simple as described. Similar galls were collected by Dr. A. W.

D. bicornis forms galls on the same hosts as does ). minusculus. Types.—U.S.N.M. No. 60125: Type and one paratype. Paratypes also in C.A.S., and A.M.N.H. Host — Quercus agrifolia. Gall (pl. 17, fig. 18) —Small brown galls up to 2.7 mm. in diameter, shaped like a depressed sphere with a minute pit in the center above. Produced on upper side of leaves of Quercus agrifolia, Q. wislizent, and rarely on Q. kelloggii in the fall and dropping when mature. Said to be so numerous sometimes as to defoliate the tree. Some years these galls are not common. Habitat—The types were reared from galls collected October 22, 1939, on Quercus agrifolia on Mount Diablo, Calif. Adults emerged April 17, 1941. Galls have been noted on this host at some 40 local- ities between Alpine and Ukiah and Red Bluff, Calif. They are also common on Quercus wislizeni and have been seen on Quercus helloggi afew times. The guest fly, Synergus agrifoliae Ashmead, often reared from it, varies much in color pattern and has been redescribed as Synergus maculatus Fullaway (1911) new synonymy, and as Synergus obscurus McCracken and Egbert (1922), new synonymy. 338 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 Genus CALLIRHYTIS Foerster CALLIRHYTIS CORRUGIS (Bassett) When I previously reported (Proc. Ent. Soc. Washington, vol. 33, p. 225, 1931) that this species had been taken in numbers ovipositing in buds of Quercus maxima, Q. velutina, and Q. palustris at various dates in April at East Falls Church, Va., the gall from which they had emerged was not known. It can now be reported that the species has now been reared from “stone” galls in acorns of all the above oaks— galls not distinguishable from those of Callirhytis fructuosa Weld. Acorns of red oak were collected in Loudoun County, Va., on Septem- ber 22, 1940, and from them fructwosa emerged April 19, 1942, and corrugis May 4, 1943, and April 20, 1947. Acorns of pin oak were col- lected at East Falls Church, Va., on October 20, 1940. C. corrugis (Bassett) emerged April 12, 18, 26, 1942; April 18, 1944; April 14, 1945, and April 6, 1946. Two species thus sometimes make similar galls in acorns of the same host oak. The alternating gall produced by these adults which oviposit in buds has not yet been discovered. CALLIRHYTIS MODESTA (Osten Sacken) Tn the box of Bassett cynipid types in the American Entomological Society the type of Cynips papula Bassett, a synonym of modesta, is a female of Ceroptres sp., a guest fly. A pinned specimen in another case marked “cotype” is the maker of the gall and has now been made the type. This is in spite of the fact that the original description of papula was drawn from specimens of two genera and combined the head and thorax of the guest with the abdomen and wing of the maker. CALLIRHYTIS CISTELLA, new species Female—Head and thorax amber, dull; abdomen red, shining; propodeum and tips of antennae infuscated.

Differs in shape and structure from all other known “pip” galls. 340 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 Habitat—The type material was collected at Mineral Wells, W. Va., by Dr. A. D. Hopkins on September 4 and October 8, 1948. By September 12 most of the specimens had fallen to the ground, and he estimated that there were over a bushel of the galls (from 50 to 100 to a square foot) under this one large tree. Adults emerged from an outdoor breeding cage at Falls Church, Va., on March 28 and April 1, 6, 14, 1945, March 29 and April 5, 1946, and April 12, 18, 1947. Galls on this host have been seen at Washington, D. C., and Rosslyn, Va. Alternating generation unknown.

Ventral spine slender, longer than hind tibia. Using width of the head as a base the length of mesonotum ratio is 1.2; antenna 2.1; wing 4.2; ovipositor 4.8. Range in length 2.85-3.8 mm. Average of 18 specimens 3.29 mm. It seems to be related to those species of the genus that are reared from root galls. Has a much longer ventral spine than @. fulva Weld. Types —U.S.N.M. No. 60128: Type and four paratypes. Paratypes also in A.M.N.H., C.M.N.H., A.N.S.P., C.A.S., and M.C.Z. Hosts.—Quercus coccinea and Quercus falcata, Spanish oak.

No. 60129: Type and seven paratypes. Para- types also in A.M.N.H., C.M.N.H., A.N.S.P., C.A.S., and M.C.Z. Host.—Quercus palustris. Gall (pl. 17, fig. 21).—Small, somewhat globular galls, 3-4 mm. in diameter covered with short, straight, stiff brown hairs, scattered along midrib or main veins on upper side of leaf in the fall and dropping off singly when mature. The hairs do not weather away during winter. Similar to galls of C. infuscata (Ashmead) on Quercus laevis in Florida. Habitat—The types were reared from galls collected on ground at East Falls Church, Va., on October 12, 1943. Adults emerged March 20, 24, 1945, and one was cut out alive on January 2, 1946. Others emerged March 20, 29, 1948, from galls collected September 15, 1946. One was cut out December 1, 1919, from a gall collected at Ironton, Mo., on October 15,1917. Similar galls have been noted on nine other species of red oaks. CALLIRHYTIS SUBCOSTATA, new species Female —Black; sides of pronotum and legs in part amber.

Using width of the head as a base, the length of mesonotum ratio is 1.3; antenna 2.1; wing 4.0. Length of four specimens 2.45, 2.25, 2.1 and 2.0 mm. Types —U.S.N.M. No. 60130: Type and one paratype. Paratype also in A.M.N.H. Host.— Quercus stellata. Gall (pl. 16, fig. 10).—Produced on the side of the acorn cup when the latter is about 4 mm. in diameter and dropping off when mature in late May. Green, 2.5-3.0 mm. in diameter, ribbed like a melon with about 16 grooves, pinkish in the grooves. Habitat—The types emerged April 1, 1950, from galls collected at East Falls Church, Va., on May 29, 1949. The nutritive layer was then about used up and the galls about ready to drop. This isolated tree had been visited almost every spring for many years but these galls had never been seen there before. US, GOVERNMENT PRINTING OFFICE: 1952 PROCEEDINGS OF THE UNITED STATES NATIONAL MUSEUM SMITHSONIAN INSTITUTION U. S. NATIONAL MUSEUM Vol. 102 Washington : 1952 No. 3305 NOTES ON MAMMALS FROM THE NILE DELTA REGION OF EGYPT By Henry W. Serzer From Jury 12, 1946, to April 9, 1947, Ens. P. Quentin Tomich col- lected mammals from the Nile Delta while serving with Naval Medical Research Unit No. 3. In addition to the large collection made by Ensign Tomich, Lt. S. M. Wheeler, of the United States Typhus Com- mission, obtained some specimens in the Cairo area. Earlier, in 1924, Miss Annie M. Alexander obtained a small collection from the Cairo area and from the Fayum. The former two collections are on deposit in the United States National Museum while the latter is on deposit at the Museum of Vertebrate Zoology of the University of California (MVZ) and has been made available for study at this time by Dr. Alden H. Miller. Since impetus is being given study of the role wild mammals play in diseases of man, a brief diagnosis of the external characters plus comments on taxonomic problems as relating to the commoner mammals from Egypt, as based on the above-mentioned material, will be useful to epidemiologists working in the Nile Delta region. It will be noted that in certain cases names have been validated from Etienne Geoffroy St.-Hilaire, 1803. The “Catalogue des Mammi- féres du Muséum National d’Histoire Naturelle” meets all require- ments for Linnaean names as established by the International Commis- sion on Zoological Nomenclature. In all instances the descriptions are clearly recognizable. It is believed that the statement of Isidore Geoffroy St.-Hilaire, to the effect that his father never intended the above work for a scientific treatise, should not be accepted, inasmuch as the work is clear, concise, and was published and circulated. 343 967605—52——1 344 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 The Tomich collection is perhaps the largest and most complete single collection known from the Nile Delta region. Even so, several species that have occurred and presumably still occur in that region were not taken by the collectors on whose work this paper is based. For the sake of completeness, references to these have been extracted from the literature. In addition there are four species which have been taken from the Delta region within historic time but have since been extirpated. They are: Wild sheep, Ammotragus lervia; dorcas gazelle, Gazella dorcas; saberhorned oryx, Orya algazel; and addax, Addaaw naso- maculata. Capitalized color terms are from Ridgway, “Color Standards and Color Nomenclature” (1912). All measurements are given in milli- meters and all weights in grams. No comments have been made in regard to habitats or habitat pref- erence, since Tomich hopes to publish an account of the natural history of these animals and their role in epidemiology.

Specimen examined.—One. Giza Province: Talbia. Description—Entire upper parts Prout’s Brown, shading rather rapidly on the lower sides to dark gray, which covers the entire ventral surface with the exception of a small patch of brownish hairs on the throat; tail of uniform color around and finely covered with long whitish hairs; dorsal surfaces of hands and feet grayish, shad- ing to white on the digits; palms and soles naked.

Measurements.—No external measurements were available but the skull of an adult male from Talbia, Giza Province, measured : Greatest length 29.0; occipitonasal length 26.4; greatest width of braincase 12.5; least interorbital width 5.5; length of palate 12.0; width across M? 9.3; length of tooth row (incisor to M*) 12.8; width of rostrum 3.6. CROCIDURA FLOWERI Dollman This species is known from Giza and Beltim. It is apparently rare and hard to obtain. It differs from Crocidura oliviert in smaller size (head and body 57-71 mm. as opposed to 93-110 mm. in @, olivier). No specimens have been examined. CROCIDURA RELIGIOSA I. Geoffroy St.-Hilaire This is the smallest Crocidura to be found in the Nile Delta. It apparently is fairly common in the Giza Gardens and in the country near Abu Rauwash. The head and body range from 45 to 55 mm. in length, thus separating this species from the other, larger, species of Crocidura known to occur in the same general area. No specimens have been examined. SUNCUS CRASSICAUDUS Lichtenstein Despite efforts of several collectors to retake this species in Suez and Suakin, Sudan, it has not been found. It is thought that it is probably the same animal as the Swneus found along the coastal re- gion of India and that the individuals known from North Africa are merely fortuitous travelers come ashore from some trading ves- sel. It may be distinguished, if ever retaken, from specimens of the 346 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 larger species of Crocidura by the presence of two more teeth in the jaws (total of 28 in Crocidura and 30 in Suncus). No specimens have been examined. Order CHIROPTERA Family PTEROPIDAE ROUSETTUS EGYPTIACUS (E. Geoffroy St.-Hilaire) Pteropus egyptiacus EB. Grorrroy ST.-HiLarrE, Ann. Mus. Nat. Hist. Natur.

Description.—Upper parts between Drab and Hair Brown, shading to between Light Drab and Drab on the underparts; all hairs uni- form in color to base; membranes of wings and uropatagium, in dry specimens, blackish; feet, uropatagium and forearm for half its length, sparsely furred; uropatagium reduced to a semicircular mem- brane, extending but slightly beyond the rump; tail short, barely ex- ceeding the narrow rim of the uropatagium; hind feet large, strongly clawed; thumb long; index finger with small claw; toes of hind feet with short bristlelike hairs; ears large, somewhat pointed; tragus absent. Measurements —Averages and extremes of two males and five fe- males from Gezira Island, Cairo, were, respectively: Total length 152 (148-154), 145.4 (134-162) ; length of tail 14 (18-15), 13.4 (12-14) ; length of forearm 91.5 (88-95), 87.8 (85-95); length of hind foot 27.5 (26-29), 27.5 (27-28); length of ear from notch 23 (23), 22.2 (22-23) ; greatest length of skull 42.7 (41.8-43.6), 40.96 (39.2-42.8) ; basal length 41.1 (40.2-41.9), 39.2 (37.2-41.5) ; occipitonasal length 41.0 (40.0-42.0), 39.2 (37.8-41.2) ; greatest zygomatic breadth 25.85 (24.6-27.1), 24.4 (22.8-26.2); breadth of braincase 16.75 (16.5-17.0), 16.7 (16.3-17.1); canine to M® 16.8 (16.4-17.2), 16.1 (15.4-16.9) ; weight of two females 125.0 (109-141). Remarks.—Anderson (1902) regards Vespertilio aegyptiacus Lin- naeus, in Hasselquist, 1757, as being the first name to be applied to these bats. This is erroneous since the description in 1757 is not ten- able but does state that V. aegyptiacus has a tragus, that it is of small domestic mouse size and that the tail is the same length as the body. The name, if it were tenable, would have to be used for Rhinopoma microphyllum.

Specimens examined.—Twelve. Giza Province: Cairo area, Saqqara Pyramids, 11; Pyramids of Giza, 1. Description—Upper parts Mouse Gray shading to whitish below; membranes of wing brownish; ears light brownish, nearly naked; face but sparsely covered with fine grayish hairs; tragus free of pinna and spatulate. Tail as long as or longer than head and body, three- fourths of which is completely free of the uropatagium; ears joined by a ridge across the forehead; hind legs long. Measurements.—Averages and extremes of seven males and four females from Saqqara Pyramids, Cairo area, were, respectively : Total length 139 (127-145), 141 (139-143); length of tail, 59.8 (54-67), 60.5 (58-63) ; length of forearm 68.4 (66-71), 68 (67-69) ; length of hind foot 16.5 (16-17), 16.2 (16-17) ; length of ear from notch 20.2 (19-22), 20.2 (19-21) ; greatest length of skull 20.6 (20.2-21.3), 20.2 (19.8-20.3) ; condylobasal length 18.6 (17.7-19.5), 18.1 (17.8-18.4) ; occipitonasal length 17.6 (16.9-18.4), 17.2 (16.7-17.3) ; greatest zygo- matic width 12.1 (11.5-12.6), 11.95 (11.8-12.1); width of braincase 8.5 (8.2-8.8), 8.5 (8.4-8.6) ; canine to M® 7.7 (7.3-8.0), 7.5 (7.4-7.6) ; weight 19 (14-25), 17.5 (17-19). Remarks.—As may be noted from the measurements, there is a considerable amount of variation in size of these bats. On the basis of size, Thomas described Rhinopoma cystops from Luxor, Egypt. This species may be distinguished from the smaller 2. cystops by the longer forearm, darker coloration, and larger skull in all measurements taken.

Tail as long as or longer than head and body, three-fourths of which is completely free of the uropatagium; ears joined by a narrow ridge across the forehead; hind legs long. 348 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 Measurements —Averages and extremes of nine males and three fe- males from 8 miles southwest of Cairo, at the Pyramids, were, re- spectively : Total length 135 (128-143), 131 (125-188) ; length of tail 68.0 (64.0-73.0), 65.0 (61.0-70.0) ; length of forearm 57.5 (55.0- 60.0), 55.3 (53.0-57.0) ; length of hind foot 13.3 (18.0-14.0), 13.8 (13.0-14.0) ; length of ear from notch 19.0 (18.0-20.0), 19.8 (18.0-21.0) ; greatest length of skull 18.1 (17.9-18.4), 17.6 (17.2-17.9) ; condylobasal length 16.1 (15.9-16.2), 15.6 (15.5-15.7) ; occipitonasal length 14.9 (14.7- 15.1), 14.4 (14.2-14.6) ; greatest zygomatic width 10.4 (10.2-10.7), 10.86 (10.8-10.4) ; width of braincase 7.6 (7.4-7.7), 7.3 (7.8) 5 canine to M* 6.3 (6.2-6.4), 6.0 (5.9-6.1). Remarks.—The specimens listed above vary in some detail from the measurements given by Thomas in his description of the species. These measurements of the Cairo specimens are all somewhat larger but are definitely smaller than those given for the larger species Rhinopomamicrophyllum. Thanks to C. C. Sanborn, curator of mam- mals, Chicago Natural History Museum, measurements of specimens of &. cystops from various localities throughout the Middle East have been made available to me. A topotypical series of 17 specimens of FR. cystops are only slightly smaller than the measurements given for the Cairo series above. It is apparent that Flower (1932, p. 385) was in actuality comparing specimens of P. cystops from the type locality and from the Cairo area. He thus arrived at the conclusion that #. cystops was conspecific with R. microphyllum. That this conspecific- ity is not real is shown by a comparison of the measurements listed for the two species in the present paper. The two species were found together, by Tomich, at the Pyramids of Giza. Among these specimens the larger, darker 2. microphyllum is easily differentiated.

Description.—Upper parts Hair Brown shading into Cinnamon- Drab on the lower parts; wings, uropatagium, feet and ears, blackish ; muzzle, chin, rump, under surfaces of femora, uropatagium, ears and wing membranes, naked, with the exception of a narrow strip of whitish hairs running the entire length of the membrane on the under- side of the forearm. Tragus large and truncate; tail about one-fourth of total length, free from uropatagium for about one-half its length, sparsely covered with long whitish hairs. Measurements.—Averages and extremes of three males from Abu Rauwash were: Total length 124 (121-126) ; length of tail 80 (28-32) ; length of hind foot 18 (18) ; greatest length of skull 28.2 (26.8-29.6) ; basal length 21.6 (21.4-21.8) ; occipitonasal length 24.4 (24.0-24.8) ; greatest zygomatic breadth 16.2 (15.8-16.7) ; breadth of braincase 11.2 (11.0-11.3) ; length of tooth row from M® to canine 11.3 (11.0-11.5). Remarks.—This bat may be told from a close relative living in the same area, Taphozous perforatus, by the bare rump, the bare under- side of the femora and the much larger skull. It is interesting that in 1924 Miss Alexander obtained only Lipony- cteris nudiventris at Abu Rauwash and in 1946 Tomich obtained only the closely allied Taphozous perforatus. 350 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 Family RHINOLOPHIDAE RHINOLOPHUS ACROTIS Heuglin Rhinolophus acrotis HreuGcuin, Noy. Act. Acad. Caesareae Leopoldino Carolinae, Halle, vol. 29, pp. 4, 10, December 1861 (Keren, Eritrea, about lat. 15°45’ N., long. 88°30’ E. Type: Adult male, labeled No. 986, Stuttgart Museum). Specimens ewamined—Four. Giza Province: Pyramids of Giza. Description—Upper parts Drab, underparts and base of hairs of upper parts Pale Drab-Gray; membranes of wing and uropatagium blackish brown; ears moderately large, rather acutely pointed, naked except at base and basal half of medial margin, tragus but a small rounded projection; noseleaf large, horseshoe shaped, dorsal projec- tion free and rather small; face and muzzle fully haired; wings and uropatagium naked; tail, enclosed in uropatagium for its entire length, about half the length of the head and body. Measurements.—Average and extremes of three males from the Pyramids of Giza were: Total length 85.0 (84-87) ; length of tail 28 (24-33) ; length of forearm 45.6 (45-47) ; length of hind foot 10.3 (9-11) ; length of ear from notch 19.3 (19-20); greatest length of skull 19.6 (19.5-19.7) ; basal length 15.6 (15.4-15.8) ; occipitonasal length 14.23 (14.2-14.3) ; zygomatic breadth 9.7 (9.6-9.8) ; breadth of braincase 8.7 (8.5-8.9) ; canine to M? 7.0 (7.0); weight of two indi- viduals 8.0 (8.0). Remarks.—The two species of Rhinolophus supposedly occurring in the Cairo area are represented here by only Rhinolophus acrotis. This species is apparently much the same in size and dorsal coloration as Rhinolophus euryale. The two species can be distinguished by the light belly and rounded dorsal projection of the basioccipital in &. acrotis and the dark belly and pointed basioccipital in F. euryale.

Specimens examined—Fifty. Lisht, Upper Egypt, 32 (alcoholic). El Maabdeh Cave, 1 (alcoholic). Oasis of Kharga, 12 (alcoholic). Henneh, 1. Nile, 4 (alcoholic). Description.—Since only one conventional skin and skull combina- tion is available, and that old and faded, an exact color diagnosis is not possible. Based on the one specimen, the color appears to have been light brown above and paler below; wing membranes and uropatagium dark brown. Nose with prominent “horseshoe” with trilobed leaf on dorsal surface; ears large, connected by narrow band MAMMALS FROM THE NILE DELTA REGION, EGYPT—-SETZER 35] across top of head; no tragus appears on either dry or alcoholic speci- mens; tail for three-fourths of its length enclosed in uropatagium, other one-fourth free. Measurements.—No skin measurements were available, but average and extreme skull measurements from five females from Lisht, Upper Egypt, were: Greatest length 18.0 (17.8-18.2); basal length 16.1 (15.6-16.6) ; occipitonasal length 14.3 (13.6-14.5) ; zygomatic breadth 10.0 (9.9-10.1) ; width of braincase 8.35 (8.38-8.5) ; canine to M?* 6.5 6.5). Pee pee this bat is not to be found in the lower Nile region, since all records thus far have come from no farther north than Saqqara, Giza Province.

Specimens examined.—Seven. Giza Province: 5 miles west of Simbillawein, 6; Maadi, 1. Description.—Hairs of upper parts tipped with Buffy Brown, black at bases; underparts lighter than back; wing membranes, in dry speci- mens, dark brown, uropatagium lighter and strongly veined; posterior margins of wings and uropatagium bordered with white; ears small, brownish and naked; tragus large; base of uropatagium furred; calcar keeled. Measurements.—Averages and extremes of five females from 5 miles west of Simbillawein and measurements of one male from the same locality are respectively: Total length, 87.2 (84-92), 89; length of tail 35.8 (382-87), 87; length of forearm 35.5 (35-86), 35; length of hind foot 8.5 (8-9), 8; length of ear from notch 12 (12), 12; greatest length of skull, 13.4 (13.2-13.6), 13.4; basal length 12.9 (12.7-18.2), 13.0; occipitonasal length 11.2 (11.1-11.8), 11.2; zygomatic breadth 8.4 (8.3- 8.6), 8.5; breadth of braincase 6.6 (6.5-6.7) , 6.6; canine to M® 4.9 (4.9), 4.9; weight 4.25 (4.0-5.0), 5.0. Remarks.—The series of bats available for study are remarkably uniform in color, in the whitish margins of the wings and uropatagia, as well as in the measurements of the skull. In one character of the skull, however, there is some variation that is rather peculiar. The first premolar on one side of the upper jaw is missing in two specimens. The tooth is extremely reduced in size in any event and even under high magnification no alveolus can be ascertained where the tooth is sup- posed to be in those specimens where the tooth is missing. These two specimens present a condition that appears to tend toward the reduced dentition of Scotozous. 967605—52——_2 302 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 109 EPTESICUS INNESI Lataste To date, there are two specimens of this bat known. They are the pair, on which the original description was based, taken by Dr. Walter Innes from a house in Cairo about 1885. Since that time no additional specimens have been recorded anywhere else in Egypt, although sought after. This bat may be distinguished from Pipistrellus kuhli by the nearly naked face and the lack of white edging on the wings and uro- patagium. No specimens have been examined. PLECOTUS AURITUS Linnaeus This bat may be distinguished from other species of bats occurring in the Nile Delta region by means of its large ears. The ears are almost as long as the head and body (head and body 45 mm., ear 35 mm.). It has been recorded from Mena House, Second Pyramid, and Minia. No specimens have been examined. Family MOLOSSIDAE NYCTINOMUS TENIOTIS (Rafinesque) Cephalotes teniotis RAFINESQUE, Precis des découvertes . . . Somiologiques. . p. 12, 1814 (Sicily). Specimen examined—One. Giza Province: near Cairo (alco- holic). Remarks —There was available to me only one specimen, preserved in alcohol. Any color diagnosis would, therefore, be worthless. The ears are large and narrowly joined across the forehead. Approxi- mately half the tail is free of the uropatagium. Nyctinomus teniotis is considerably larger than Vyctinomus aegyptiacus, at least as far as the skull is concerned, from the specimens available. In addition, N. aegyptiacus has but two lower incisors on each side of the lower jaw, while J. tenzotis has three. It appears that there has been a great deal of doubt as to the names ap- plied and as to what the respective authors were describing. Geoffroy St.-Hilaire (1818, p. 129), in deseribing WV. aegyptiacus, says in regard to the teeth, “Les dents deviennent un excellent indicateur de cette organisation ; les incisives sont au nombre de deux en haut, et de quatre en bas: celles-la sont fortes, coniques et contigues, quand les secondes sont tres-petites et comme entassees au devant des canines.” It thus appears that the plate and the published description are at variance, since he states in the latter that there are four incisors below and the plate appears to show six. Is it possible that the artist interpreted the cingulum of the canine as an incisor?’ In De Winton’s review of Nyctinomus he states there are four incisors in V. aegyptiacus and six in J. tentotis, yet he raises a question as to what JV. aegyptiacus actually is in the published work of Anderson on the mammals of Egypt. MAMMALS FROM THE NILE DELTA REGION, EGYPT—SETZER 353 From specimens of identified V. aegyptiacus from Basutoland, X. teniotis is at once distinguished by its larger size and the occurrence of three instead of two incisors in each mandible. Order LAGOMORPHA Family LEPORIDAE LEPUS AEGYPTIUS Desmarest This is the largest of the hares to be found in Egypt. It has long, thin hind legs; the hind feet are long and narrow; the ears are about 134 times the length of the head; and the tail is black bordered with brown. It is known to occur in Giza and Fayum Provinces. No speci- mens have been examined. LEPUS ROTHSCHILDI De Winton A medium-sized hare, characterized by short, stout hind legs; broad, short hind feet; ears about 114 times the length of the head; and the tail black, edged with white. On these characters it can be distin- guished from L. aegyptius. It also is known to occur in Giza and Fayum Provinces.

Hist., ser. 7, vol. 9, p. 45-46 [p. 45], January 1902 (Mandara, east of Alexandria, B.M. No. 92.7.1.5). Specimens examined.—Kight. Behera Province: one-half mile west of Dikheila Airfield, 4; one-half mile east of Muntazah, 4. Description.—Upper parts between Ochraceous-Buff and Ochrace- ous Orange; hairs plumbeous at base with a subterminal band of the above color and a terminal band, very minute, of black. Black hairs freely intermixed with banded hairs, thus presenting a somewhat subdued hue. Color purest on sides, flanks, cheeks, rump, and nose. Entire underparts, muzzle, most of the vibrissae, hind and forelegs, dorsal and ventral surfaces of hands and feet, supraorbital and postauricular spots, white. Tail penicillate, ochraceous above shad- ing to yellowish white beneath; tip on dorsal surface with longish brown hairs. Ears blackish, sparsely covered with fine white hairs inside and ochraceous on the outside. Eye bordered by narrow black ring. 354 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 Measurements.—Averages and extremes of two males and two fe- males from one-half mile east of Muntazah were, respectively: Total length 222 (219-224), 215 (207-223); length of tail 122 (120-125), 119 (113-125) ; length of hind foot 30 (30), 28 (27-29) ; length of ear from notch 15.5 (15-16), 15.5 (15-16); occipitonasal length 29.1 (28.9-29.3), 28.2 (28.2); length of palate 12.95 (12.8-13.1), 12.5 (12.3-12.7) ; length of palatal foramina 5.5 (5.4-5.6), 5.2 (5.1-5.3) ; length of auditory bulla 8.85 (8.8-8.9), 8.75 (8.7-8.8) ; crown length of upper molar series 3.85 (3.8-8.9), 3.85 (3.8-3.9); least interorbital width 5.9 (5.8-6.0), 5.75 (5.7-5.8). Remarks.—Gerbillus gerbillus andersoni may be distinguished from what is here considered the nominate race from 5 miles northwest of the Pyramids of Giza by darker dorsal color and longer more pig- mented ear. Cranially it may be distinguished by longer rostrum, larger teeth, more inflated auditory bullae, longer, narrower braincase, longer incisive foramina, and more robust zygomata.

Suez Canal Zone: 3 miles northwest of Fayid, 12. Description—Upper parts Pinkish Cinnamon, hairs plumbeous at base, subterminal band of above color, minute terminal band of some hairs blackish. Color purest on sides, flanks, cheeks, and nose; entire underparts, muzzle, most of the vibrissae, hind and fore legs, dorsal and ventral surfaces of hind and fore feet, supraorbital and postauric- ular spots, white. Ears flesh-colored, nearly naked. Eye bordered by narrow black ring. Measurements—Averages and extremes of four males and six fe- males from five miles northwest of the Pyramids of Giza were: Total length 222 (216-227), 211 (203-217) ; length of tail 127 (123-181), 120 (113-128) ; length of hind foot 30 (29-81), 28.5 (28-29) ; length of ear from notch 12 (12), 12 (12); occipitonasal length 27.3 (27.2-27.4), 26.6 (26.2-26.8) ; length of palate 12.2 (12.1-12.5), 12.1 (11.7-12.5) ; length of palatal foramina 4.5 (4.3-4.6), 4.4 (4.8-4.6) ; length of auditory bulla 8.7 (8.5-8.8), 8.4 (8.3-8.8) ; crown length of upper molar series 3.45 (3.4-3.5), 3.5 (3.4-8.6) ; least interorbital width 5.85 (5.8-5.9), 5.7 (5.4-6.0) ; weight 21 (19-22), 19 (18-21). Remarks.—This small gerbil, represented by 37 specimens, is re- markably constant in measurement and color. In external measure- ments it is about the same as Gerbillus gerbillus andersoni. The two MAMMALS FROM THE NILE DELTA REGION, EGYPT—SETZER 355 subspecies can, however, be readily distinguished by their coloration and the longer darker ear and by the noticeably larger skull of G. g. gerbillus.

Specimens examined.—Three. Giza Province: 1 mile northeast of Kom Aushim. Description—Upper parts Clay Color, purest on sides and cheeks; with a strong admixture of black on the back; hairs plumbeous at base in all pigmented hairs; underparts, forelimbs, dorsal surfaces of fore and hind feet, ventral half of tail, supraorbital and postauricular spots and muzzle, white. Ears brownish, nearly naked, bordered by thin blackish line; dorsal surface of nose, blackish ; eye bordered by narrow black line; dorsal surface of tail as back color but with more admixture of black, which increases toward the black penicillate tip. Soles of hands and feet naked. Measurements.—Averages and extremes of three males from 1 mile northeast of Kom Aushim, were: Total length 195.3 (191-202) ; length of tail 110 (106-115) ; length of hind foot 23 (22-24); length of ear from notch 12.3 (12-13) ; occipitonasal length 25.0 (24.2-25.8) ; length of palate 11.2 (10.6-11.7) ; length of palatal foramina 4.5 (4.34.7) ; length of auditory bulla 7.9 (7.7—-8.2) ; crown length of upper molar 356 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 series 3.43 (8.4-3.5) ; least interorbital width 4.6 (4.5-4.9); weight 19 (16-22). Remarks.—It seems hardly logical that this gerbil, in view of the apparent plasticity of the genus, could be the same subspecies in the Nile Valley and in Algeria. However, owing to the lack of compara- tive material, it is felt best to place the above specimens in this subspecies. GERBILLUS PYRAMIDUM PYRAMIDUM (E. Geoffroy St.-Hilaire) Dipus pyramidum BH.

Description—Upper parts Pinkish-Cinnamon, purest on sides, flanks, cheeks and muzzle; hairs of the dorsum plumbeous at base, finely tipped with black, remainder of hairs of body white at base; entire underparts, dorsal and ventral surfaces of fore and hind feet, supraorbital and postauricular spots, lower half of cheeks and muzzle, and posterior ventral half of tail, pure white; tail above, same pure color as on sides, shading in the posterior one-fourth to a penicillate black tip; ears finely covered with hair, margins of pinnae blackish; narrow black ring around eye. Tail not quite so long as head and body; hind feet relatively short. Measurements —Two males from 1 mile northeast of Abu Rauwash and two females from 3 miles northeast of Mt. Abu Rauwash meas- ured, respectively: Total length 232, 255; 229, 252; length of tail 128, 135; 129, 189; length of hind foot 34, 35; 33, 83; length of ear from notch 15, 15; 15, 15; occipitonasal length 31.5, 33.0; 29.9, 82.1; length ef palate 14.5, 15.0; 13.8, 14.5; length of palatal foramina 5.9, 6.0; 5.8, 6.1; length of auditory bulla 9.0, 9.7; 9.1, 10.0; crown length of upper molar series 4.3, 4.3; 4.2, 4.2; least interorbital width 6.6, 7.2; 6.5, 6.8; weight 37, 56; 32, 42. Remarks.—In the series of specimens available at this time are what appear to be two color phases. However, when these animals are examined critically, these “phases” are seen to be juvenile and adult pelages. The juvenile pelage is darker than that of the adult and appears to be retained longer than in most species of rodents. With respect to pelage these darker animals appear to fit the description of Gerbillus pyramidum tarabuli, and it is possible that this subspecies is based on immature specimens of @. p. pyramidum. However, until MAMMALS FROM THE NILE DELTA REGION, EGYPT—SETZER 357 such time as a concerted effort is made to obtain specimens and to study this genus throughout its range, all of the animals cited above are here referred to Gerbillus pyramidum pyramidum. PACHYUROMYS DUPRASI NATRONENSIS De Winton Pachyuromys dupresi (sic) natronensis DE WintToN, Noy. Zool., vol. 10, p. 285, August 25, 1903 (Bir Victoria, on the way to Wadi Natron from the Nile Valley, Egypt). Specimens examined.—Two. Giza Province: West of Abu Rau- wash, Cairo area, 1 (MVZ). Egypt: Presumably near Cairo, 1. Description—Upper parts Pinkish-Cinnamon, individual hairs plumbeous at base and finely tipped with black; color purest on sides, flanks, cheeks and top of muzzle; hairs of cheeks and muzzle, where pigmented, white at base; entire underparts, lower half of cheeks, thighs, dorsal surfaces of hands and feet, tips of ears, and supra- orbital spots, white; all unpigmented hairs white to base; tail finely covered with white hairs. Tail short and heavy, becoming expanded more or less club-shaped distally and in dry specimens flattened dorso- ventrally; hind feet small; ears rather large. Measurements.—An adult female, labeled only Egypt but presum- ably from near Cairo, measured: Total length 165; length of tail 55; length of hind foot 24; occipitonasal length 35.3; length of palate 15.8; length of palatal foramina 6.4; length of bulla 16.5; crown length of upper molar series 4.4; least interorbital width 6.3. Remarks.—This animal superficially resembles Meriones libycus but may be readily distinguished from that species by the short, club- shaped, fatty tail and by a greater extension of the nasals and much larger, more inflated bullae. The immature animal lacks the bright color of the adult and appears instead much darker, owing to the greater amount of basal plumbeous and black tipping of the hairs. In the immature skull, the general conformation is the same but minor changes occur as adulthood is reached. ‘The space between the mastoid portions of the auditory bullae is greater in the immature, no supraorbital ridge is developed, the nasals appear to encroach more into the frontals, the interparietal becomes slightly smaller and the wings of the supraoccipital become more defined as the animal ages.

Suez Canal Zone: 3 miles northwest of Fayid, 2. 358 PROCEEDINGS OF THE NATIONAL MUSEUM VOL, 102 Description.—Animals from near Heliopolis have the upper parts Warm Buff with a moderate admixture of black; color purest on sides, flanks and cheeks; entire ventral surface, dorsal and ventral surfaces of hands and feet, muzzle, postorbital and postauricular spots, white; tail above as color of back, shading to a black penicillate tip; purer color on ventral half of tail. AJIl pigmented hairs plumbeous at base. Eye bordered by narrow black ring. Ears light brownish, finely covered with white hairs inside and out. Part of vibrissae white, part black. Measurements.—Averages and extremes of three males and seven females from five miles east of Heliopolis, were, respectively: Total length 265.3 (256-274), 242 (226-261) ; length of tail 126.3 (123-182), 120.0 (108-132) ; length of hind foot 33.3 (83-34), 31.5 (380-33) 5 ear from notch 18 (17-19), 16 (11-18) ; occipitonasal length 39.2 (38.6- 39.7), 35.9 (34.8-37.6); length of palate 16.7 (16.4-17.1), 16.1 (15.5-16.9) ; length of palatal foramina 6.6 (6.5-6.7), 6.3 (5.6-6.6) ; length of auditory bulla 14.8 (14.5-15.6), 13.9 (18.1-14.7); crown length of upper molar series 4.7 (4.6-5.1), 4.5 (4.4-4.7) ; least inter- orbital width 6.0 (5.5-6.4), 5.9 (5.4-6.3); weight 85.6 (77-100), 59.0 (50-71). Remarks.—Ellerman, in March 1941 (p. 533), places the species Meriones shawii as a pure synonym of Meriones libycus libycus, and on the same page (533) places Meriones crassus as a subspecies of M. libycus. In May 1947 he elevated Mf. crassus to full specific rank and removed M. shawii from synonomy, making it a subspecies of M. Uibycus. In raising M. crassus to full specific rank, he considered that nine subspecies properly belonged to this former subspecies. The subspecies he placed under M. crassus belonged to the species M. libycus, M. schouesboei, M. erythrourus, M. ismahelis and M. arimalius. In October 1947 Ellerman and Chaworth-Musters listed eight subspecies of M. libycus, nine of M. crassus, and placed M. shawit as a full species with three subspecies. In none of the papers cited above do Ellerman, or his coauthor, Chaworth-Musters, give any reason for suppressing or resurrecting species or subspecies. In “A Revision of the Genus Meriones,” Chaworth-Musters and Ellerman (1947) cite as key characters: Hind claws dark, M. libycus, and hind claws pale, M. crassus. In addition to the claw character he gives the joined or closely aproximated processes around the supra- meatal triangle as a character distinguishing WM. libycus. In M. crassus the processes are not supposed to be closed or closely approxi- mating. In specimen U.S.N.M. No. 282509 one hind foot has dark- colored and the other hind foot has pale-colored claws. Several other specimens in the series show a similar condition but not quite so pro- MAMMALS FROM THE NILE DELTA REGION, EGYPT—SETZER 359 nounced. The processes around the suprameatal triangle are also variable. In U.S.N.M. Nos. 282509 and 282512, as examples, one side shows the processes closed or nearly approximating, while the other side is open and not closely approximated. From this and from the indecision in placing species, it thus ap- pears that the degree of variation being dealt with is certainly not on a specific but rather on a subspecific level.

Measurements——No external measurements were available; a sub- adult male skull from Damietta measured: Length of palate 17.3; length of palatal foramina 5.6; crown length of upper molar series 5.53 least interorbital width 6.5; length of nasals 13.7. Remarks.—In the absence of comparative material and since these specimens are topotypical they are here referred to Psammomys obe- sus nicolli. PSAMMOMYS OBESUS OBESUS Cretzschmar This subspecies of sand rat is known from the Alexandria area and may be distinguished from P. 0. nicolli, from Damietta, solely on the basis of its lighter color. No specimens have been examined. Family SPALACIDAE SPALAX AEGYPTIACUS Nehring The mole rat is apparently only locally distributed in the region around Mariut and Ramleh near Alexandria. Its presence may be ascertained by small mounds of earth thrown out of its burrow system in much the same manner as the pocket gopher of North America. 360 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 Even though these animals show no extenal eye, there is supposed to be a minute, completely organized eye present under the skin.

Behera Province: Alexandria, 1 Fayum Province: Lake Fayum, 1. Description.—Dorsal hairs tipped with Ochraceous-Tawny, bases and other hairs of the dorsum throughout their length, blackish ; strong admixture of blackish hairs on dorsum, becoming fewer on sides and rump; nose, ring around eyes and hairs of ramp Buckthorn Brown; tail bicolored, blackish on dorsal surface, but sparsely haired ; ears rather large, rounded and but finely covered with hair; hairs of belly, ventral surfaces of fore and hind legs white-tipped, these hairs with blackish bases; immature pelage darker. Tail about equal to head and body in length; hind feet rather long; thumb expressed as a rudimentary claw only. Measurements.—One adult male from Lake Fayum, Fayum Prov- ince, measured: Total length 321; length of tail 141; length of hind foot 38; length of ear from notch 20; length of palate 16.9; length of palatal foramina 8.5; crown length of upper molar series 6.5; length of nasals 14.6; least interorbital width 5.4; weight 56.0. Remarks—On superficial examination these animals are surpris- ingly like the North American Cricetine genus Sigmodon, both ex- ternally and cranially. From recorded habitat observations they both occupy much the same ecological niche.

MAMMALS FROM THE NILE DELTA REGION, EGYPT—SETZER 361 Measurements.—Averages and extremes of five males and two fe- males from Alexandria, Behera Province, were, respectively: Total length 398 (370-428), 415 (415) ; length of tail 195.4 (182-207), 196.5 (194-199) ; length of hind foot 42 (40-46), 40 (89-41) ; length of ear from notch 19.6 (19-20), 19 (19) ; greatest length of skull 46.4 (44.5- 49.5), 27.2 (47.0-47.4) ; condylobasal length 41.1 (39.3-48.9), 41.8 (41.5-42.1) ; length of palate 22.3 (21.5-24.2) , 22.2 (21.9-22.6) ; length of palatal foramina 7.9 (7.4-8.4), 7.85 (7.7-8.0) ; alveolar length of upper molar series 7.5 (7.47.6), 7.4 (7.3-7.5) ; least interorbital width 6.6 (6.4-7.0), 7.0 (6.9-7.1) ; length of nasals 17.2 (15.8-19.3), 17.75 (17.5-18.0) ; greatest zygomatic width 22.7 (21.0-25.4), 22.85 (22.8- 22.9). Remarks.—As may be noted from the measurements, these rats show a great amount of age variation. No effort was made to segregate senile from subadult individuals for the purposes of measurement. It is interesting to note that the averages of individuals from the four areas represented are quite close to one another. There are no observa- ble peculiarities in these introduced rats. RATTUS RATTUS (Linnaeus) Mus rattus LINNAEUS, Systema naturae, ed. 10, p. 61, 1758 (Sweden). Specimens examined.—Thirty-four. Behera Province: Alexandria, 11. Daqahlia Province: 5 miles west of Simbillawein, 4. Giza Province: Cairo, 11; Kafr Taharmes, 2; Talbia, 4. Suez Canal Zone: Fayid, 2. Description.—Three basic color types of this species occur in the Delta region. They are: (1) Blackish brown upper parts, with plum- beous belly and hands and feet; (2) grizzled brown upper parts with buff-tipped plumbeous-based hairs on the belly and brownish hands and feet, the toes of both hands and feet whitish; (3) dorsal color as in (2) but somewhat lighter, with underparts white, washed with yellowish, the hands and feet whitish. Tail longer than head and body, but finely covered with hair; annulations pronounced; ears large and rounded. Temporal ridges of skull more or less in the form of a lyre, never parallel as in R. norvegicus; anterior upper molar without accessory cusp. Measurements.—Averages and extremes of eight males and nine females, all of the third color type, from several localities were, re- spectively: Total length 412 (378-432), 406 (355-460) ; length of tail 227.5 (208-249), 294.2 (194-262) ; length of hind foot 36.5 (34-38), 35.6 (33-87) ; length of ear from notch 23.5 (21-25), 24.8 (24-96) ; greatest length of skull 42.3 (40.6-44.3) , 42.7 (39.6-46.6) ; condylobasal length 36.9 (35.0-37.8), 36.7 (33.4-40.7) ; length of palate 19.6 (18.6- 362 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 20.0), 19.6 (18.1-21.4) ; length of anterior palatal foramina 7.4 (6.8- 8.3), 7.6 (7.0-8.3) ; alveolar length of upper molar series 6.8 (6.3-7.2), 6.9 (6.5-7.8) ; least interorbital width 6.1 (5.8-6.3), 6.1 (5.6-6.6) ; length of nasals 14.9 (18.5-15.8), 15.2 (13.3-17.0). Remarks.—lf one were to recognize subspecies of the commensal rat then the three color types mentioned under description would become (1) Rattus rattus rattus, (2) Rattus rattus alecandrinus (which may be considered topotypical), and (8) Rattus rattus frugivorous. How- ever, since the three basic color types do not appear to segregate out in any given series from any given locality as just these three color types, but show in six of thirty-four specimens intermediate conditions be- tween any two of the three, it is felt that here, as in Acomys, 1s an ex- pression of some genetic factor, called by some a single gene character for melanism. Certainly, one of the criteria for subspecies is a free interbreeding between two or more contiguous kinds which would be expected to produce intermediate types. It is extremely hard, though, to visualize three distinct subspecies occupying the same environmenta! niche. Flower (1932, p. 409) and many others mention the fact that no habitat differences could be ascertained between the so-called three subspecies. It may be that if these animals were to be found ferally, one or the other of the three types would segregate and be com- pletely recognizable. It is worthy of mention, though, that the four wild-caught animals from 5 miles west of Simbillawein show all three color types plus one that is intermediate between types two and three. It is felt that, since there appears to be no segregation, so far as is known, it is best to ignore the subspecific names for the three above- mentioned rats until such time as these names can be shown to be valid.

Behera Province: Alexandria, 6; 1% mile west of Dikheila Airfield, 1; Heliopolis, 1; Maadi, 1. Dagahlia Province: 5 miles west of Simbillawein, 3. Giza Province: Kafr Taharmes, 1; Kuniessa, 1; 'Talbia, 1. Suez Canal Zone: Port Said, 1; Suez, 2. Description—Three color phases are present in the small series from Egypt. They are: (1) Pallid Neutral Gray rather strongly in- termixed with black; (2) Cinnamon-Brown without so much black intermixed; and (3) Mummy Brown, strongly suffused with black. In all color phases the hands and feet are white; the bellies in the first two phases are white; in the first the hairs are white to the bases, in the second the hairs are plumbeous at the base; in the third phase the belly is buffy, with the hairs plumbeous at the base. In all three MAMMALS FROM THE NILE DELTA REGION, EGYPT—SETZER 363 phases the tail is more or less bicolored and the dark dorsal stripe cor- responds to the back color. In the first phase, the ears are pale, re- sembling the dorsal color; in the second and third phases the ears are dark, as isthe dorsal color. The skulls show no one feature that might tend to segregate any of the above color phases as subspecies. They are all regarded as Mus musculus. Measurements—Averages and extremes of two males and four females from Alexandria, Behera Province, were respectively : Total length 157 (156-158), 166.2 (157-173); length of tail 78 (78), 78.7 (74-82) ; length of hind foot 17 (17), 17.3 (17-18) ; length of ear from notch 18 (13), 13.3 (18-14) ; greatest length of skull 21.7 (21.2-22.2), 21.7 (21.0-22.4); occipitonasal length 21.2 (20.8-21.6), 21.0 (20.5- 21.7); length of palate 10.05 (9.8-10.3), 9.9 (9.6-10.4); length of palatal foramina 5.2 (5.2), 4.7 (4.5-5.0) ; crown length of upper molar series 3.15 (3.1-3.2), 3.2 (3.0-3.4) ; length of nasals 7.9 (7.8-8.0), 7.8 (7.5-8.3) ; least interorbital width 3.55 (38.5-3.6), 3.5 (8.5); greatest zygomatic width 11.05 (11.0-11.1), 10.9 (10.6-11.1). Remarks.—The names applied to the house mice of the Delta region appear to be in as much confusion as are the names applied to Acomys and to Rattus. It is not thought wise to try to solve the nomen- clatural mix-up on so few specimens. The material available is ex- tremely heterogeneous and shows all the types that have been rec- ognized from the Nile Delta and southward. Mus musculus gentilis, which occurs in a feral condition farther south along the Nile, appears to be the name most applicable to the largest numbers of animals from the Alexandria-Cairo-Suez area. There are, however, individuals that would appear to belong to the north European stock of Mus musculus musculus and Mus musculus domesticus. In addition, there are specimens of a light color phase from Alexandria that do not correspond to any of the named kinds of Mus musculus supposed to be in this area. Cranially, all the speci- mens examined appear to be of one subspecies. It is thought best, at this time, merely to refer the house mice of northern Egypt to the species Mus musculus.

Nubia: Abu Simbel, 1 (MVZ). 364 PROCEEDINGS OF THE NATIONAL MUSEUM VoL. 102 Description—Upper parts from between Ochraceous-Orange and Ochraceous-Tawny to deep slate gray; belly yellowish to light slate gray. Color on body nowhere pure; in light phase strongly suffused with black-tipped hairs; in dark phase uniformly slaty. Hands, feet and tail of both color phases as belly color. Tail equal to head and body in length, strongly annulated and with small bristlelike hairs. Pelage coarse but becoming spinose between the ears and spines increas- ing in size and number over the rump. Ears large, rounded, and but sparsely covered with fine yellowish hairs. Measurements.—Averages and extremes of two males and six fe- males from Alexandria, Behera Province, Egypt, were, respectively : Total length 209.5 (198-221), 218.6 (208-225) ; length of tail 113.6 (108-121), 106.6 (97-112) ; length of hind foot 19 (18-20), 18 (18); length of ear from notch 18.5 (17-20), 18 (17-20); greatest length of skull 28.05 (27.0-29.1), 28.28 (27.9-28.9); condylobasal length 23.85 (22.7-25.0), 24.0 (23.4-24.8) ; length of palate 14.55 (13.5-15.6), 14.32 (18.7-15.0) ; alveolar length of upper molar series 4.3 (4.2-4.4), 4.4 (4.4); length of palatal foramina 6.3 (6.2-6.4), 62 (5.8-6.6) ; least interorbital width 4.8 (4.8), 4.7 (4.64.8) ; length of nasals 10.3 (9.9-10.7), 10.6 (10.2-11.1). Remarks.—These small spiny mice have, at various times, been designated by various specific or subspecific names. Most of these names have, apparently, been based on differences in color. From the specimens now at hand, it appears that the only name strictly applicable is Acomys cahirinus. KE. Geoffroy St.-Hilaire evidently had before him a specimen of the light-colored phase when he de- scribed this animal, and subsequent authors must have had repre- sentatives of the other more melanistic types. In all, the two basic types of pelage color are light above and light below and dark above and dark below. From these two phases all possible gradations can be demonstrated by specimens from Abassia Fever Hospital, in Cario, or from Alexandria. From ail appearances this peculiarity of color is nothing more than the expression of melanism. In many ways these small mice recall the variation of pelage found in Rattus rattus and considered by many to be subspecies.

Suez Canal Zone: 3 miles northwest of Fayid, 6. Description—Upper parts between Vinaceous-Cinnamon and Pink- ish-Cinnamon; hairs plumbeous at base, grading into above color and finely tipped with black; sides and flanks with hairs white to base with a slight admixture of the above colors; entire ventral surface, anterior and ventral surface of thighs, forelegs, hip stripe, postauricu- lar and postorbital spots, muzzle, cheeks, tip and ventral half of tail, white. Ears about as dorsal coloration, sparsely covered with fine white hairs. Eye bordered by narrow black ring. Tail above, for proximal two-thirds, as dorsal color; other one-third divided sub- equally by proximal black ring, incomplete ventrally, and a distal white tip. Measurements.—Averages and extremes of two males and four females from 5 miles northwest of the Pyramids of Giza were, respectively: Total length 293 (292-294), 294.5 (284-801) ; length of tail 179 (176-182), 182 (176-188) ; length of hind foot 62 (60-64), 61.7 (60-65) ; length of ear from notch 19 (19), 19.2 (19-20) ; occipi- tonasal length 30.0 (30.0), 30.2 (29.6-30.7) ; greatest length of skull 33.1 (83.1), 33.1 (32.6-33.9) ; length of nasals 10.65 (10.4-10.9), 10.9 (10.4-11.4) ; least interorbital width 11.9 (11.8-12.0), 12.1 (11.5-12.7) ; length of palate 15.6 (15.6), 15.6 (15.2-15.9) ; length of palatal foram- ina 4.35 (4.3-4.4), 4.25 (4.24.3); length of bulla 14.0 (14.0), 13.8 (13.5-14.2) ; width of skull across bullae 22.6 (22.6), 21.3 (21.1-21.5) ; width across maxillary arches 22.5 (22.3-22.7) , 22.0 (21.3-22.5) ; crown length of upper molar series 4.5 (4.44.6), 4.75 (4.7-4.8) ; weight 50.0 (48.0-52.0), 53.0 (51.0-56.0). Remarks.—If the animals from 5 miles northwest of the Pyramids of Giza are considered topotypical, a slight difference is noted in the size of the crania and the length of the hind foot from those animals from 8 miles northwest of Fayid and 5 miles east of Heliopolis. The pelage in the animals from the latter two localities has less reddish and more black admixture, thus presenting a somewhat darker tone. Order CARNIVORA Family CANIDAE CANIS LUPASTER Hemprich and Ehrenberg Apparently the jackal is not uncommon. The status of the name applied to the jackal of this region is in some doubt. It can be dis- tinguished from the domestic dog by its shorter muzzle, wider face, and brighter coloration.

Giza Province: Cairo Area, Abu Rauwash (MVZ). Description.—Colors of this animal are white and blackish brown. White distributed on the body as small mystacial patches; a narrow white ring occurs between the eyes and ears, then turning ventrad around the point of the jaw and meeting on the bottom of the throat; tip of ears white; base of a more or less lyre-shaped band of white begins in back of the ears and behind the forehead stripe, the band running posteriorly and somewhat lateroventrad to cross the flanks and continue to the base of the tail; inside this large lyre is a smaller lyre-shaped band of white, which becomes closed at the base of the tail; inside the loop of the median lyre is a more or less diamond- shaped patch completely encircled by black and with a small black spot in the center. The outermost lyre-shaped band continues onto the dorsal surface of the tail to the tip and for approximately one-half the ventralsurface. The posterior ventral half of the tail has black-tipped white hairs. Entire ventral surface covered with blackish brown hairs. Ears small and rounded; soles of hands and feet, with the exception of the pads, haired; eyes small.

Description—Color : Under fur shading from Isabella Color on neck and shoulders to Cinnamon-Rufous on rump, thighs, and base of tail. Guard hairs long (about 65 mm.) and eight-banded, with alternating white and black bands; tips of guard hairs brownish instead of black as rest of bands; face, chin, muzzle, and dorsal surfaces of hands and feet, blackish; palms and soles naked; belly sparsely haired. Entire animal, owing to banded hairs, presents a grizzled appearance. Ears small and rounded; tail not quite so long as head and body, and owing to the banded hairs appears to be ringed; tail more or less tufted at tip.

Family FELIDAE FELIS CHAUS Schreber This cat is apparently to be found throughout the Delta region, usually in low marshy places. It may be distinguished from the feral Felis catus by its shorter tail (less than one-half the head and body length) ; by its larger, black-tipped ears; and by its reddish feet. It is apparently not uncommon. No specimens have been examined. MAMMALS FROM THE NILE DELTA REGION, EGYPT—SETZER 369 LITERATURE CITED ALLEN, G. M. 1939. A checklist of African mammals. Bull. Mus.

S. NATIONAL MUSEUM Vol. 102 Washington: 1952 No. 3306 THE SIPUNCULID WORMS OF CALIFORNIA AND BAJA CALIFORNIA By Water Kenrick FIsHer SIPUNCULID is the name informally bestowed on members of a small phylum of marine wormlike animals of world-wide distribution—the Sipunculoidea.!. These creatures live from the intertidal zone to oceanic depths, in tubular excavations in mud and sand, in clefts of rocks, in masses of coral, in borrowed shells, under rocks, in holdfasts of kelp, or in almost any protected situation that affords access to reasonably clear water and food. They are not found in shifting sand or mud, since in such habitats they are likely to be buried or else deprived of protection. Their food is finely divided detritus selected or trapped by the ciliated tentacles, or bottom material actively swallowed. This latter material is not necessarily finely divided. It is sometimes coarse, including the miscellaneous small fragments of the hard parts of Foraminifera, corals, bryozoans, an- nelids, mollusks, echinoderms, and crustaceans, often very abundant, especially in calcareous sands. 1 Adam Sedgwick, in his ‘Students’ Textbook of Zoology”’ (vol. 1, p. 594, 1898), first accorded this group phyletic rank. It had long occupied in the Annelida the position of a poor relation, as one of the orders of the class Gephyrea, in which Quatrefages also placed the Echiuroidea and Priapuloidea. ‘‘Gephyrea’’ either as a class or a phylum is an unnatural and unsatisfactory association, but one which has been singu- larly viable.

The material has been accumulating over a considerable period of years and includes specimens dredged by the United States Fisheries steamer Albatross in 1904. Unfortunately only about a third of the Albatross collection was in a condition suitable for study when it became available in 1946. The Harriman Alaska Expedition (1899), through Dr. Wesley R. Coe and the late Dr. William E. Ritter, made a small but important contribution. By far the largest collections were contributed by Prof. G. E. MacGinitie, Dr. W. F. Thompson, and the late Edward F. Ricketts. I am also indebted to the United States National Museum and the Museum of Comparative Zoology for the loan of material, to Dr. J. H. Gerould for the loan of reprints, and to Dr. Elisabeth Deichmann and Dr. Elise Wesenberg-Lund for extracts from the important works of Leuckart and Diesing. For contributions of material thanks are due to the following persons: Dr. M. W. de Laubenfels, Dr. D. F. Hoffmeister, Dr. C. L. Hubbs, Prof. Trevor Kincaid, Dr. S. F. Light, W. H. MacGinitie, E.

L. Ray, and Dr. D. M. Wootton. As compared with Japan the sipunculid fauna of the west coast of North America is meager. Phascolosoma agassizii is the dominant intertidal species from Kodiak, Alaska, to Point Conception, Calif. Its range extends to northern Baja California. Ph. puntarenae is its equivalent from Cape San Lucas to Panama. Dendrostomum pyroides occurs from Coos Bay, Oreg., to northern Baja California, while D. dyscritum has been taken between Point Conception and the northern boundary of California. D. zostericolum has been found from Point Conception to Ensenada, Baja California. D. perimeces, a consistent inhabitant of sandy mud, probably colonizes estuaries and sloughs from an off-shore, shallow-water population. It has been taken between Bodega Head and Venice, Calif. D. hexadactylum, which resembles pyroides, has been found only in 10 to 20 fathoms, in Monterey Bay. It was described from Japanese waters. The conspicuously large Siphonosoma ingens is a southern California species, extending north to Monterey Bay. Sipunculus nudus is an off-shore cosmopolite, which finds its way into estuaries of southern California and into the intertidal zone of Baja California and the Mexican coast. The genus Golfingia (formerly Phascolosoma) is a negligible element in the shore SIPUNCULID WORMS OF CALIFORNIA—FISHER 373 fauna of California, only three inconspicuous species having been found: @. margaritacea californiensis, G. hespera, and G. macginitiet, all rare or very local in occurrence. Only two sipunculids are known from Alaska: Golfingia margaritacea (Sitka, Kilisnoo, Dutch Harbor, Point Barrow) and Phascolosoma agassizii (Cape Fox, Prince William Sound, Kodiak). Undoubtedly G. vulgaris occurs in shallow water. Phascolosoma agassizii has been taken from intertidal stations on Vancouver Island and the Queen Charlotte Islands, British Colum- bia, and G. margaritacea has been taken at Vancouver Island. Washington has four species, all from Puget Sound and vicinity: Golfingia vulgaris, G. margaritacea, G. pugettensis, and Phascolosoma agassizi. Two species are known from Oregon (Coos Bay): Dendrostomum pyroides and Phascolosoma agassizv. With this unimpressive showing, I need hardly emphasize that this paper is not a definitive treatment of the fauna. While it is improb- able that many new intertidal forms will come to light, it is equally probable that the list of shallow-water and deep-sea species is very far from complete. In this paper I have used Golfingia Lankester in place of Phas- colosoma authors and have replaced Physcosoma Selenka with Phas- colosoma Leuckart in order to conform to accepted rules of nomen- clature. For the same reason I have employed Dendrostomum Grube, the original spelling, instead of Dendrostoma, a later emendation by Keferstein. KEY TO THE GENERA OF SIPUNCULOIDEA a’.

(Type, S. nudus Linnaeus.) Diagnosis.—Usually large species with long cylindrical body and short, sharply differentiated introvert covered with squamiform papillae. Trunk generally thick walled, and longitudinal and circular muscle layers divided into regular fascicles. Skin divided into ree- tangular areas by longitudinal and circular furrows. Posterior end of body rounded or bluntly pointed and sometimes marked off from main trunk by a limiting ring fold of skin. A flat tentacular fold surrounds oral disk and from its margin tentacles of varying com- plexity develop. No hooks on introvert or papillae on the trunk. Description.—The longitudinal muscle bundles rarely anastomose. Characteristic of the genus are longitudinal integumentary canals corresponding to the intervals between the muscle bundles and com- municating with the coelom by slits between the regular circular fascicles of muscles that are external to the longitudinal. The canals contain coelomic fluid and anything floating in it. Retractor muscles four, separated to head; nephridia two; spindle muscle present or absent; a dorsal and a ventral contractile vessel without appendages; especially characteristic is an accessory intestinal spiral (pl. 18, fig. 1, A) between the end of esophagus and the beginning of the true spire, and coiled in the latter. Esophagus and intestine anchored by very numerous fixing muscles. ‘‘A median-dorsal unpaired epithelial tube opens upon the surface of the head immediately behind the tentacular fold, and leads backward to a cerebral sense organ anterior ¢ The genus erroneously called Physcosoma Selenka, 1897. 376 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 and ventral to the brain. The esophageal connectives do not surround the attachments of the retractor muscles to the head, as in most sipunculids, but lie behind and beneath these attachments” (Gerould, 1913, p. 427). The brain is conspicuous. On its front is a con- spicuous cerebral organ or frons, sometimes elaborately lobed (Fisher, 1947, pl. 10, fig. 2; pl. 11, fig. 3). The ventral nerve cord is not attached anteriorly by a mesentery to the wall of the introvert, as in Siphonosoma. It is supported on each side by a strong paraneural muscle originating from the first, or first and second, muscle bundles just posterior to beginning of introvert. Remarks.—Plate 18, figure 1, shows the accessory intestinal spiral A dissociated from the regular spiral B. This is easily accomplished by clipping the fixing muscles that hold it in place. I have figured (Fisher, 1947, pls. 10, 11) this extra spiral in situ in Sipunculus polymyotus and S. galapagensis, where the bends X and Y are indicated. The details of the fixing muscles are so different in these two species as to suggest that they may be of value in classification. The accessory spiral is not present in Xenostphon or in Siphonosoma. SIPUNCULUS NUDUS Linnaeus PuaTE 18 Sipunculus nudus LinNaEvs, 1766, p. 1,078. Remarks.—This is perhaps the best known and certainly one of the most widely distributed species of sipunculids—a truly eurythermal type. On the west coast of America it occurs from Monterey Bay, Calif., to Panama. It is found on the coast of Brazil, in the West Indies, and north to Beaufort, N. C. In Europe it inhabits the North Sea, English Channel, and the Mediterranean and Adriatic Seas. It is reported from the Red Sea, Indian Ocean, East Indies, China, Japan, along the western part of the Pacific (Yap, Loyalty Islands), and South Australia.’ The specimens recorded below have 30 to 33 muscle bundles. The ventral retractor muscles arise from longitudinal muscles 1-7, 1-6, or 2-5 (Ensenada) ; the dorsal retractors arise from 9-15, 10-14, 10-15, 11-16. A large specimen from southern California is 190 mm. long, but others are considerably smaller, circa 130 mm. The longest specimen is 290 mm. and was washed ashore at Pacific Grove, Calif., during a heavy surf. The species has not been found at Monterey Bay in intertidal situations, even at Elkhorn Slough, which has been rather thoroughly explored by Prof. G. E. MacGinitie and others; but it occurs in sub- tidal situations, since many were washed ashore during a period of spring tides and heavy surf. It seems probable that Newport Bay 7 A specimen sent me by S. J. Edmonds from Port Willunga, south of Adelaide, South Australia, is super- ficially like S. nudus but belongs to another, probably new, species.

Genus XENOSIPHON Fisher Xenosiphon Fisuer, 1947, p. 360. (Type, Sipunculus branchiatus W. Fischer.) Diagnosis.—Differing from Sipunculus sensu stricto in the following particulars: Integumental coelomic spaces in the form of independent sacs of irregular outline; an extra pair of muscles functioning as retractors and protractors arising from posterior border of introvert and inserted in front of brain; rectum unusually long, the anus being in front of nephridiopores; postesophageal intestine without a long forward loop; nephridia long, slender, attached to body wall for nearly their entire length; squamiform papillae of very short introvert increasing in size toward the tentacles, which have very many leaflets arranged in subtriangular pads surrounding the mouth; type species with papilliform dermal outgrowths. XENOSIPHON BRANCHIATUM (Fischer) PuaTE 19 Sipunculus mundanus var. branchiatus W. Fiscuer, 1895, p. 3, pl. 1, figs. 1, la, 2. Sipunculus branchiatus SPENGEL, 1913, p. 74. Xenosiphon branchiatum FisuER, 1947, p. 360, pl. 12. Description.—The following description is based chiefly on three specimens from Panama. Length 310 mm.; introvert and tentacle crown 20-25 mm.; thickness of cylindrical body 8-12 mm., this varying according to constriction of ring muscles. The specimen from La Paz, 420 mm. long, is constricted in the middle of body to 8 mm. diameter. Longitudinal muscle bands 29-34, only rarely anasto- mosing. When the body is fully inflated the longitudinal and circular muscles divide the surface into flat rectangular areas separated by rather inconspicuous grooves, but when constriction takes place there is apparent a series of more or less convex annuli. The middle third of the body, except for a ventral zone, about six muscle bands in width, 378 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 is closely covered with slender pointed papilliform outgrowths of the cuticle, 1-1.5 mm. long, which give a furry appearance to skin. These papillae communicate with irregularly zigzag subcutaneous canals, above which the cuticle usually forms slight welts, which have a direction oblique to the longitudinal axis of the dermal rectangles. Each rectangle has its own canal, independent of the others (pl. 19, figs. 4, 5). Beyond the papuliferous area these canals—or more properly spaces, as they are usually branched—can be traced forward half the distance to the head, and also posteriorly, as they are often self-injected with yellowish material from the coelom. On the periphery of the papuliferous area a papilla usually appears, first at the anterior end of the canal, next at the posterior end, then in between, until there are four or five to each rectangle. Brown or yellow, finely divided material, which is sometimes loose in the canals, is also found in the bottom of the papillae. If the top of the canal is stripped off, a pore at either end is seen to lead deeper into the tissue (arrows in pl. 19, fig. 4). If ordinary ink is forced from the coelomic side into the pores that exist at intersection of longitudinal and transverse muscle bands, it appears in these pores at the ends of the subcutaneous canals but is usually blocked by material already in the canal. The papillae are highly iridescent in sunlight. The area strongly reminds one of the papularium of a sea star, and the function is probably the same, i. e., respiratory. The terminal knob of the body is very short, broadly rounded to subtruncate, and the slight margin is capable of disappearing under distension. ‘There is a conspicuous terminal pore, and the skin, either smooth or longitudinally ridged, is closely beset with microscopic pores of at least two sizes. The short introvert is covered with squamiform papillae, which increase in size toward the front, near which they decrease over a narrow zone to the bare zone behind the tentacles. The largest papillae are 0.75-1 mm. in length and breadth. The tentacles are composed of very numerous small grooved foliate elements in subtriangular mats or groups, radiating from the mouth, which is ventral to the center. There are seven of these from which ridges of tissue converge to the mouth, two dorsolateral, two lateral, and two ventral, the odd one being the middorsal and much the largest. On the periphery of the crown the space between the major groups is filled in with one to three small groups of tentacles, which probably increase in number as growth proceeds. The anus is equivalent to about five muscle rings (not clearly differentiated) behind the posterior papillae of the introvert. Interiorly the longitudinal muscles form flat bands becoming angular in section only when the body is much constricted. The SIPUNCULID WORMS OF CALIFORNIA—FISHER 379 introvert and the four retractors occupy about one-seventh of the body length. The retractors are free from one another and arise at approximately the same level. Both ventrals arise from muscles 1-4, while both dorsals arise obliquely from muscles 7-11. The two protractors arise from muscles 12-15 at the posterior border of the introvert. Before insertion, 4 mm. in front of the brain, they pass over the dorsal retractors. Their form and position, with the introvert out and in, are shown in plate 19, figures 1 and 2. The rectum passes far forward and opens close behind the (dorsal) origin of the pro- tractors. (Muscles 17 and 18 are the two middorsal in figure 1; 18 and 19 are really 17 and 16 of the left side.) The rectum lacks thin, fan-shaped wing muscles. “719d fear ihe bith ida abel me ne gidgis, .iexe mGrk Weill) OF tailed ae fe Teel eet $A prvi tBthe° syn wrote me gate eid a Te oot thal) aeiay 4 : Dulin tA Py ce os E pod clay) tree 47. l ff Poth wtoie bh) stigdhese Piney ale ran’ hie t T : By , . ree yee alg ; worth Mod south tyas mots “ 7 / i 7 mee, iitivor. aren vied’.

S. NATIONAL MUSEUM Washington : 1952 No. 3310 Vol. 102 REVIEW OF THE FISHES OF THE BLENNIOID GENUS ECSENIUS, WITH DESCRIPTIONS OF FIVE NEW SPECIES By Witzert M. Cuapman! and Lronarp P. Scuurrz McCottocu described the fish genus #’csenius on the basis of a new species, #. mandibularis, from Australian waters. Norman further defined the genus and indicated that several other species of blennies, formerly referred to Salarias Cuvier, should properly be included in Eesenius. The present study is a review of the genus and the species included in it. Ecsenius is a closely knit genus of 11 known marine species occurring only in the tropical Indo-Pacific faunal area. Within that area species have been found from the Red Sea on the west through the Marshall and the New Hebrides Islands to the Hawaiian Islands on the east and from Formosa on the north to Queensland, Australia, on the south. While this genus occurs in the coral area, in relation to coral heads, it typically occurs not on the shallow reefs but apparently in moderate depths, and this perhaps accounts for the relative scarcity of specimens in ichthyological collections. The dentition clearly sets off Zesenius from all other genera of blen- nies. In the upper jaw are more than 100 tiny, independently movable teeth, a condition typical of the genera Jstiblennius Norman and Salarias, whereas in the lower jaw, the labial teeth are fewer than 50 in number, they are much stouter than those above (usually with the one or two teeth on each side farthest from the symphysis somewhat 1The senior author was aided in these studies by grants in aid from the John Simon Guggenheim, Jr., Memorial Foundation and by the California Academy of Sciences, 507 969588—52——-1 508 PROCEEDINGS OF THE NATIONAL MUSEUM yOu. 102 enlarged or stronger than the others), and they are only slightly flex- ible. This condition suggests Rhabdoblennius, and is distinctly in contrast with that of Salarias and Istiblennius. The canine far back on, the lower jaw, typical of salariin blennies, is tiny but stout, and may be one or two in the same species. Furthermore, as Norman has reported, traces of more teeth in this same dentary series can be de- tected. Indeed, in the genotype #. mandibularis there are six or seven plainly apparent teeth on each dentary in this series, quite dis- tinct from the series of labial teeth on the anterior part of the dentaries, a situation quite unknown in other salariin blennies. Norman has suggested, on this account, that . mandibularis might be properly placed in a separate subgenus. A study of the other species of the genus has, however, inclined us to reject this suggestion. In all other particulars, #. mandibularis agrees closely with the other species of the genus. The types of that species are considerably larger than specimens available in the other species. It is possible that these latter are mostly juvenile and that the greater number of dentary teeth in #. mandibularis is simply a factor of age, representing an adult condition detectable as traces of teeth noted by Norman in other species. While the condition of the dentition might indicate a relationship somewhere between /stiblennius, Salarias, and Rhabdoblennius, there is little else that does, and no lineal phyletic connection is apparent between H’csentus and those three genera. The lack of orbital or nuchal cirri, the low number of dorsal spines, the unbranched caudal rays, the full membranous connection of the last anal ray to the caudal peduncle, the slender genital tube of the male, the elongation of one or more caudal rays well beyond the fin membrane, which is normal in most species, the lack of crenulation on the lips, the pelvics 1,3, the short lateral line with its double, rather than single, line of pores, are characters that are mostly confined to H'csenius among the salariin blennies, and, when put together, set the genus off sharply from its relatives. There are other more subtle but just as definite characteristics—the slender fin rays, which give an air of diaphanous fragility to the vertical fins, and the anterior profile, which is either vertical or even slopes backward from the forehead to the margin of the upper lip. The distribution of the known specimens and species of the genus is suggestive of the division of the vast tropical Indo-Pacific fish fauna into subareas, illustrated by the other genera of Salariinae and other families of fishes studied by the authors. Two species have been found FISHES, GENUS ECSENIUS—-CHAPMAN AND SCHULTZ 509 only in the Red Sea and at Djibouti; two have been found only in the Solomon Islands; one each in the Marshall Islands, northeast Australia, the Philippines, Formosa, the Hawaiian Islands, the west- ern Indian Ocean, and the Persian Gulf. Only one species has been determined to have a broad range, occurring in Ceylon, Bengal, Christ- mas Island, Timor, and the New Hebrides Islands. In discussions under each species some notes have been made of the possible relation- ships of the several species, but clarification of these relationships must await further collections throughout the range of the genus.

Certain measurements were made on the types and these data are recorded in thousandths of the standard length in table 2. Head (tip of upper lip to end of gill cover) 3.6 to 4.0; greatest depth 3.8 to 4.7, longest pectoral ray 5.2 to 5.8, snout tip (upper lip) to anus 1.8 to 1.9, anal fin base 2.5 to 2.7, all in the standard length.

No orbital cirrus; no nuchal cirrus; a single, simple, nasal cirrus arising on upper edge of nasal opening; snout profile with a notable backward slant of 25 to 30 degrees from the vertical; edges of both lips smooth; lateral line running a dorsal course over pectoral fin and ending about opposite tip of pectoral fin and base of eighth or ninth dorsal spine, not descending to middle of side; vertical line through FISHES, GENUS ECSENIUS—-CHAPMAN AND SCHULTZ 515 dorsal origin passes through rear edge of opercle, base of pectoral fin, and notably far behind base of pelvics; last dorsal ray attached by membrane to dorsal edge of caudal peduncle but not to base of caudal fin; anal origin opposite base of last dorsal spine; last anal ray at- tached by membrane to lower edge of caudal peduncle; pectoral fins reaching about two-thirds the way to the anus; anal spines small, first embedded; posterior canine of lower jaw short but strong; teeth in upper jaw about 110, movable, those in lower jaw larger, movable, about 40 to 45 in number, the teeth on each side farthest from the symphysis notably enlarged; no vomerine teeth; posterior margin of caudal fin probably truncate; no cephalic crest; a vertical line through front edge of upper lip passes through front edge of eye; forehead a little in front of tip of upper lip. Coloration—In aucouou: Background coloration plain reddish brown; a large area in front of anus blackish brown; on base of caudal fin and on caudal peduncle a dark brown spot, somewhat angular posteriorly ; pectoral, pelvics, dorsal, and caudal fins hyaline or pale; anal fin dusky brown; a narrow dark brown streak extends from lower edge of eye backward to rear angle of opercle, below this dark streak on opercle is a narrow pale streak that continues on body behind head only, just dorsal to base of pectoral fin. Autve (based on color sketch made on A/batross): Background coloration reddish brown; anal spot purplish black; caudal! spot black; anal reddish brown; dorsal spines orange; an orange streak along base of dorsal fin; iris orange; dark streak behind eye is dark blue, and pale streak below it is orange; upper lip slightly yellowish brown. Ecology.—This species probably came from deep water, as the Albatross dredge record indicates 244 fathoms. Remarks.—£, stigmatura is one of two known species with a black area (purplish black when alive) in front of the anus; £. lividanalis, new species, lacks the caudal spot and streaks behind the eye.

Remarks.—As in most other species of the genus, the males and females of this species cannot normally be differentiated by the ex- ternal sex organs. Examination of the gonads of the types of both pulcher and anomalus demonstrates that the former is the male, the latter is the female of the species. It is quite possible that this is the cognate in the western Indian Ocean of opsifrontalis from the Marshall Islands and pro-oculis from the Solomon Islands.

Coloration—Mate: Head and anterior two-thirds of body almost uniformly dark brown (bluish in life) ; blackness of peritoneum makes abdomen darker than above; in posterior third of body this dark area 524 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 shades off into a very pale area, which extends over the caudal; this pale area bright golden in life; pale area extends anteriorly farther along base of anal, and a little way along base of dorsal; on smaller specimens the dark pigment extends farther posteriorly until there may even be a little on the base of the middle caudal rays, but always the fish is lighter posteriorly than anteriorly ; no spots or markings on the head or body, except for an indistinct light band from the eye down across the upper lip and an indistinct dark streak directly behind the orbit; a continuous dusky band along basal portion of dorsal back to where light area of body begins, covering basal two-thirds of spinous dorsal, where it contains, over the first three spines, a horizon- tal, elongate, black streak; anteriorly the distal part of spinous dorsal clear except for margin; posteriorly this dark margin becomes wider until it melts into lower dusky band; soft dorsal with a dusky marginal band, but remainder of fin clear except for basal pigment anteriorly and a little pigment along each ray; in smaller specimens the dusky basal band extends to end of soft dorsal; anal fin with a fine clear band mesially, on anterior rays, which broadens posteriorly to cover base and more than half of fin; rest of fin, including whole distal edge, dusky except for fleshy pads on tips of rays, which are lighter ; caudal entirely pale; pectoral rays dark, especially lower ones, but membranes clear and light; pelvics dusky, but lighter than body next to them; eyes almost black, as are the nasal cirri. FrmaLte: Same as male ex- cept light posterior part of body continued to part of caudal peduncle, more of anal dusky, and there is some pigment on the distal two- thirds of middle of caudal. Remarks. —While the description of bécolor by Day is brief and the fin counts contain either none of the spines, or not all of them, there is no question but that he was dealing with this well-marked species, as is true of the specimens described by Johnstone as S. furcatus and Hora and Mukerji as S. burmanicus. The series of specimens described as S. melanosoma from Christmas Island might be considered as being subspecifically distinct from the above, for all these specimens have 18 soft rays in the anal (all the New Hebrides specimens have 19 or 20 soft anal rays), the upper and lower caudal rays either do not project, or project less than one- fourth the length of middle caudal rays, and the color is a uniform rich brown, scarcely lighter below than above. However, of the three specimens from Ponape one had 18 soft anal rays and the other two had 19, and there is no clearly distinguished color break posteriorly. One has the caudal rays extended by the length of the middle caudal rays, the other two by less than one-third the length of the middle caudal rays. There is no dependable evidence in this group of sub- speciation. FISHES, GENUS ECSENIUS—CHAPMAN AND SCHULTZ 525 The specimen from Timor is identical with the New Hebrides speci- mens except that it has only 18 soft anal rays. Coloration well marked. Ecsenius namiyei is doubtless the Formosan cognate of this species, marked particularly by the greater number of dorsal and anal rays, and the uniform coloration of the body. Escenius frontalis is very likely the Red Sea cognate of this species, well marked, however, by the single nasal cirrus and the 15 pectoral rays.

Coloration——Body purplish red, paler posteriorly; dorsal fin with narrow oblique darker markings; anal darker along margin, with a similar median band. Remarks.—This is undoubtedly the Formosan cognate of F. bicolor. The three more rays in dorsal, one more in anal, and the oblique mark- ings of the dorsal prevent synonymizing it with bicolor in the absence of a series of specimens for comparison. 526 PROCEEDINGS OF THE NATIONAL MUSEUM VoL. 102 ECSENIUS HAWAIIENSIS, new species Figure 96 Holotype.—U.S.N.M.

Coloration.—In alcohol, olive-brown to light greenish brown; darker dorsally, paler ventrally ; the posterior part of body not notably paler than anterior part of body as is #. bicolor; middle of sides with five to seven short narrow vertical white bars not wider than pupil and about two to four times longer than wide, the lower edge of these bars a little below midlengthwise axis of body, then they continue dorsally, fading out gradually before reaching base of dorsal fin; pectoral, dorsal, and anal fins dusky; pelvics slightly dusky; caudal fin with outer rays white or nearly so, the middle rays dusky; behind eye is an obliquely oblong blackish blotch, margined with pale; a pale streak extends posteriorly from behind middle of eye a short distance; corner of mouth white or pale. 528 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 102 Remarks.—This new species belongs to the group of species center- ing around £. bicolor but differs from that species chiefly in coloration ; hawaiiensis has short white bars on the midsides, whereas bicolor is plain brown without markings. Doubt might be cast on the source of this material, “a dry dock hauled from Guam about a year ago,” if with this new species (which did not occur in the extensive collections made in the Marshall and Marianas Islands by a group of collectors during and after the war) other species had not been taken as follows: Scorpaenopsis cacopsis (known only from the Hawaiian Islands), Cirrhitichthys aprinus, a specimen of Apogon, several specimens of gobies not yet identified, 2 specimens of an unidentified species of Acanthurus in the settling stage of late metamorphosis, specimens of Pseudochromis tapeinosoma and Tripterygion hemimelas (common to the Marshall, Marianas, and Hawaiian Islands) having about one more scale on the average than those from the Marshall and Marianas Islands, and Gymnothorax undulatus (common to all three named localities). We conclude that the fishes in this collection are endemic to the Hawaiian Islands and were not transported in the drydock brought from Guam.
