Von Dr. Asajiro Oka, Tokio. : ; Unter dem Hirudineen-Material, das ich vor einiger Zeit aus China erhalten habe, befindet sich ein kleiner, der Gattung Ozobranchus zugehöriger Fischegel, welcher bei Wutschang anf einer Flussschild- kròte schmarotzend gefunden wurde. Derselbe stellt eine neue, bisher unbeschriebene Spezies dar und ist deswegen besonders interessant, dass er durch die Zahl und Lage der Kiemenanhänge gewisse Ähnlichkeit mit dem Genus Branchellion aufweist. Auch der Um- stand, dass er im Süsswasser erbeutet wurde, ist beachtenswert, da die Gattung Ozobranchus sonst auf das Meer beschränkt ist. Das einzige mir vorliegende Exemplar ist 9 mm lang und an der breitesten Stelle des Rumpfes 2 mm breit, die seitlichen Kiemenan- hänge nicht einbegriffen. Wie schon ein Blick auf die nebenstehende Figur zur Genüge zeigt, stimmt die neue Art in äusserer Gestalt mit den japanischen Stücken von Oz. branchiatus, die ich in einer früheren Arbeit” beschrieben habe, ziemlich genau überein, bis auf die Kiemen- anhänge, welche die Unterscheidungsmerkmale abgeben. Unser Tierchen ist nämlich mit 11 Paar solcher Gebilde ausgestattet, wäh- rend die Vergleichsart deren nur 7 Paar besitzt. Auch die Grössen- verhältnisse der Kiemen sind bei beiden Formen nicht die gleichen. Im Gegensatz zu Oz. branchiatus, bei welchem die Branchien nach hinten zu allmählich an Grösse abnehmen, sind diese bei der neuen 1) A. Oka, Description d’une espéce d’ Ozobranchus, Zoological Magazine, Vol. VII, No. 75. 1895. A. OKA: IS) Form alle gleichmässig entwickelt und bilden zusammen einen echten Fransensaum an beiden Seiten des Körpers. Am vordern, den Kopf und Hals umfassenden Körperteil zählt man 18 Ringe, wovon die 3 ersten auf der Bauch- seite den Mundsaugnapf bilden. Die ü- brigen Ringe sind unter sich ziemlich gleich. Die Augen, in ı Paar vorhanden, haben ihre Lage am vordern Rand des zweiten Ringes seitlich der Medianlinie. Eine scharfe Grenze zwischen dem Kopf und dem Hals lässt sich äusserlich nicht er- kennen. An der Basis des Halses, wo er in den Rumpf übergeht, befinden sich auf der Ventralseite die Geschlechtsöffnungen, die männliche und die weibliche um einen Ozobranchus jantseanus, kleinen Bruchteil einer Ringelbreite von eB ales einander entfernt. Der Rumpf setzt sich aus 27 Ringen zusammen. Diese sind aber nicht gleich gross, sondern treten haupt- sächlich in zwei verschiedenen Grössen auf und zwar in der Weise angeordnet, dass breitere und schmalere Ringe meistens abwechseln. Man beobachtet nämlich 11 breite und 11 schmale Ringe, die re- gelmässig alternieren, dann folgen 5 andre, die nach dem hintern Saugnapf zu immer an Grösss abnehmen. Von der Bauchseite ge- sehen, ist jeder der breiteren Ringe mit dem darauf folgenden schmalen Ringe mehr oder weniger vollkommen verschmolzen, so dass hier die Gesamtzahl der Ringe bedeutend kleiner ausfällt als auf der Dorsal- seite. Der hintere Saugnapf ist halbkugelförmig und wie gestielt, weil der Körper unmittelbar vor demselben stark verjüngt ist; sein Durch- messer kommt der Rumpfbreite fast gleich. Die 11 breiten Ringe des Rumpfes tragen an beiden Seitenrändern EINE NEUE OZOBRANCHUS-ART AUS CHINA. 3 je einen Kiemenanhang. Dieser zeigt genau denselben Bau wie die entsprechenden Gebilde von Oz. branchiatus ; er besteht aus einem Basalstiick und zwei, allerdings ganz kurzen Asten, die sich wiederum in je 4 bis 7 Kiemenfaden zerspalten. Sie sind alle gleichmiissig entwickelt, indem die vordersten im Vergleich mit den hintersten kaum an Grösse zuriickstehen. Dies fiel mir besonders auf, da bei zahlreichen Exemplaren von Oz. brancluatus, die ich neulich in der Sagami-See gesammelt habe, die Kiemenanhänge von vorn nach hinten so merklich an Grösse abnehmen, dass die des letzten (7.) Paares fast als rudimentär zu bezeichnen sind. Die neue Art stellt demgemäss eine Übergangsform zu dem Genus Dranchellion dar, welches ebenfalls mit gleichmässig ausgebildeten Kiemenanhängen ausgestattet ist. Merkwürdigerweise ist die Zahl der kiementragenden Rumpfsomiten bei beiden Formen die gleiche, indem sie sowohl bei Branchellion wie such bei unserm Tier 11 beträgt. Diese 11 Somiten lassen sich bei allen Ichthyobdelliden auch an einer Reihe andrer anatomischer Merkmale gut charakterisieren und sind meines Erachtens als eine besondere Körperregion aufzufassen. In diesem Zusammen- hange möchte ich noch erwähnen, dass bei Ozodranchus jeder der breiten Ringe des Rumpfes dem 1. und 2. Ring eines ursprünglich 3-ringeligen Neurosomites entspricht, wie es bereits J. PERCY MOORE?” mit Recht hervorhob, und dass die Kiemenanhänge dem zweiten, das Nervenganglion enthaltenden Ringe des betreffenden Somites zuge- hören. Das Exemplar, welches der vorliegenden Mitteilung zugrunde liegt, wurde von meinem Schuler und Freund, Herrn K. Usui in Wutschang, der dort an einer chinesichen Hochschule als Lehrer angestellt war, in der Nähe der genannten Stadt erbeutet.

Observations and Experiments on the Ctenophore Egg. III Experiments on Germinal Localization of the Egg of Beroé ovata. By Naohide Yatsu. CHUN’S isolation experiments on the egg of Eucharis multicornis carried on in the summer of 1877 and described fifteen years later (92 p. 104) had given DRIESCH and MORGAN (’95) an impetus to study more fully the development of isolated blastomeres and egg- fragments of Beroë ovata. Their study was followed by FISCHEL’S clear analytical investigation on the germinal localization of the same animal (97, ‘98 and ’03). ZIEGLER (’98) incidentally carried on similar experiments while studying the mode of cleavage of the Beroé egg after operation. These works, it seemed to me, were so satis- factorily carried out that we do not need any further experiment along this line of study. Yet when I repeated at Naples the investi- gations of the above authors in somewhat extensive ways, some new data were obtained, which embody the present paper. Of many eggs operated upon in forty different ways 216 reached two-day embryos,’ at which time they were examined and sketched. The numbers of comb-plates were recorded in each case for the pur- pose of future comparison. Instead of giving the results of individual series of experiments I shall only describe those which will serve as a supplement to FISCHEL’S thoroughgoing investigations. 1 Incidentally it may be of interest to note that in two-day embryos there is no co-ordination in the movement of comb-plates, each performing its flickering motion of its own rhythm. 6 N. YATSU: OBSERVATIONS AND EXPERIMENTS 1. Removal experiments performed prior to the formation of the polocytes. A portion of cytoplasm was cut off before the polocytes were formed ; most eggs were operated before fertilization: some may have been cut after it. It was extremely difficult to determine the exact moment of fertilization. Moreover at this time there is no landmark to orient section planes ; the record was necessarily incomplete. Of thirteen cases eleven had eight rows of comb-plates, while two had seven rows (Fig. 1). In two cases the number of comb-plates was smaller than in the normal embryos. In one case one of the entodermal pockets was short; in another two of them were short (Fig. 2). Excepting these defective cases all the rest were normal. Judging from the size of resulting embryos a considerable amount of cytoplasm must have been cut off in some cases, yet those produced from such pieces were quite normal. This taken with the fact that sectioning were performed at random, it may not be amiss to infer that the germinal stuffs for the future comb-plates and for the entodermal pockets have not yet been well localized. For the sake of comparison some eggs were cut in two between the formation of the polocytes and the beginning of the first eleavage. Of ten eggs thus operated upon three were perfect, all the others being more or less defective, as FISCHEL has found out (’03). The above two series of experiments will show that there is a decided advance in the specification of germ-regions after the formation of the polocytes. DRIESCH and MORGAN (’95 pp. 217-219) describe sixteen embryos resulting frow the removal of a certain amount of cytoplasm from the egg from three to four hours prior to the first cleavage. But since the exact time of operation in relation to both fertilization and polocyte formation has not been recorded, their results cannot directly be utilized for the question under consideration.

N 8 N. YATSU: OBSERVATIONS AND EXPERIMENTS 2. Twin embryos. It is interesting to note that from an egg which was cut in two along the equatorial plane before the beginning of the first cleavage developed two embryos (Figs. 4, 5 and 6). Unfortunately I did not record which fragment had the polocytes, two being reared in one salt-celler. But judging from the number of comb-rows, it is almost certain that the embryo represented in Fig. 5 is from the micro- meric half. The egg must have been fertilized more than one spermatozoon, one of the embryos being merogonic. At any rate the points of interest regarding these twin embryos lie in the fact that both of them had a well developed apical sense organ, stomodacum and two entoderm sacs. From this it may be concluded that the basis-of the sense organ is not restricted to one hemisphere. 3. Formation of comb-rows in the end cells and middle-cell. To determine whether the end-cells and middle-cells behave in the same way in respect to the capacity of forming of comb-rows, the following series of experiments were made. At the 8-cell stage one end-cell was separated (Fig. 7) from other blastomeres and was allowed to develop. Twelve embryos were ob- tained. All of them had one row of comb-plates and no stomodaeum (Figs. 8, 9). From two end-cells (Fig. 10) I had embryos with two rows of comb-plates and without the stomodaeum (Fig. 11) (six cases). Two middle-cells were cut out at the 8-cell stage (Fig. 14). The resulting embryos (five cases) showed a great deal of variations. In one of them two comb-rows were formed (Fig. 15) as we might anticipate. In another embryo a very small group of comb-plates was developed. In three no comb-rows were formed at all. One of ON THE CTENOPHORE EGG 9 them is represented in Fig. 16. This strikingly resembles embryos developed from two end-cells of the 16-cell stage deprived of the first micromeres (Figs. 12, 13). In comparing the above results it may be concluded that in the middle-cell the development of comb-plates is arrested in some cases. The difference in behavior between the end- and middle-cells can hardly be due to that of the degree of injury, if any, received at the 33 AD (3 ype ab 4 Figs. 7-16. x60; bigs. 8 and 9, embryos from E (Fig. 7); Fig. 11, embryos from 20 (Fig. 10); Fig. 13, embryo from 2E—2e, (Fig. 12); Fig. 13, embryo with ty comb-rows developed from 2M (Fig. 14); Fig. 16 combless embyro from 2M. IO N. YATSU: OBSERVATIONS AND EXPERIMENTS operation, but rather to that of the initial organization or some other physiological conditions. It may be interesting to add that the stomodaeum fails to develop in all the cases of the above isolation experiment, namely E, 2E and 2M.' The sense organ may be formed (tesori 75): 4. Variation in the formation of the comb-rows. It cannot de doubted that each blastomere of the 8-cell stage contains the basis for one comb-rows in it as has been ascertained by FISCHEL (97 p. 122). I tried several series of experiments and the results agree in almost all cases with his, but exceptionally I met with the cases in which the number of comb-rows was greater or less than that of the original blastomeres. The embryos developed from two middle-cells have just been described in the last section. 1E+2M gave rise to larvae with two comb-rows (six cases) (ligs. 19, 21). Fig. 20 is an embryo with three comb-rows from such combination of blastomeres. 2E+1ıM yielded larvae with two comb-rows (one case) (Figs. 17, 18) and four rows (four cases). 3E+2M should give rise five-rowed larvae, but I have three cases with six rows (Figs. 24, 25). From 2E+3M resulted four-rowed embryo (one case) (Fig. 22, 23). In the above exceptional cases one at once notices that the number of the resulting comb-rows is usually smaller than that of the blasto- meres. This may well be explained as the arrested development, but how the resulting embryo has more comb-rows than it might be expected from the number of the original blastomeres is very difficult to interpect. The latter cases may be due to unequal distribution of the ctenoplasm among the blastomeres. 1 E=end-cell, M=middle-cell. ON THE CTENOPHORE EGG i Ceno 24 Figs. 17-25. x60.

Development of the first quartet cell in isolated fragments. FISCHEL’S conclusion that the entire ctenoplasm is located in the first quartet cells (97 p. 122), was tested in various ways and that was found to hold in almost all cases, e. g., 2E +e+M+m;, produced an embryo with two comb-rows and 3M+3m+e, that with four rows In some cases, however, the first quartet cells deprived of the asabl blastomeres scem to fail to develop comb-plates altogether as is seen from the following experiments : 2E+2M+4e,+4m, should produce eight-rowed embryo but this gave rise to an embryo with six rows of comb-plates. 5E+2M+4e, +4m; also yielded an embryo with six rows ; 4E +4e, +4m, , six rowed embryo. 6. Summary. 1. Germinal localization becomes more definite after the formation of the polocytes. 2. Each of twin embryos produced from an egg by an equatorial section before the first cleavage may possess the apical sense organ. 3. Since some of the blastomeres of the 8-cell stage or, more pre- cisely speaking, those of the first quartet fail in some cases to develope comb-rows, the importance of correlative differentiation should not be overlooked in the development of the ctenophore egg. 4. Very rarely the distribution of the ctenoplasm among the blastomeres of the 8-cell stage may vary so that the number of comb- rows in resulting embryos exceeds that of the initial blastomeres.

By Hiroshi Ohshima, Rigakushi. With Plate I and 7 textfigures. Having discovered in the Holothurian material at my disposal a number of specimens referable to the interesting species Pseudocucumis japonicus (BELL), my attention was directed to the comparative study of tentaculation in the so-called ‘‘ polychirotous” Cucumarids. In the present paper will be given my views concerning the system of the group, arrived at from my studies, to be followed with descriptions of the species found in the Japanese waters. I. On Tentaculation and its Bearing on the System of Cucumariide. 1. Observations. i. Pseudocucumis africanus (SEMPER). A goodly number of specimens belonging to this species stood at my disposal, so that my observations on tentaculation were made chiefly on it. In regard to number, size and arrangement of tentacles in this species, records have been given by LUDWIG [24, p. 1237, Taf. XV., Fig. 16; 26, p. 96, Fig. 11], BEDFORD [4, p. 844, figs. HI, B—E] and MITSUKURI [82, textfig. 52]. According to these authors, the two small tentacles, situated in a pair in the midventral radius, are either equal to each other in size and stand side by side, or are of different sizes, in which case the smaller is situated at a position 54 WIROSHI OHSHIMA : inner to the larger. With regard to this point I have examined thirty-seven individuals, in all which the arrangement of tentacles, with their well protruded oral parts, could be easily made out. Of them there were found only two individuals which showed a mid- ventral pair of small tentacles of about equal size, standing side by side. One of these individuals was abnormal in that it possessed an extra tentacle, making in all twenty-one tentacles. In all the remain- ing thirty-five specimens, I have invariably found the tentacles re- gularly arranged in a way which differed from the statements of the three authors mentioned above. Of the twenty tentacles they possess, ten are large, five medium- sized, and the remaining five small. Each pair of the large tentacles (textfig. 1, D,, V,, R; and L,) is interradial in position and alternates with a pair which consists of a medium-sized (D, or R,) and a small (V, or L,) tentacle. In the paired lateral radii the small tentacle (V,) stands always ventral to the medium-sized (D,), while in the mid- ventral radius the small one (L,) is situated to the left of a medium-sized (R,). This agrees with OSTERGREN’s description of his Pseudocucumis mixta |33, p. 135, and 86, p. 3], excepting the fact that in my specimens the five small tentacles form an inner circle to the remaining fifteen. As to the position of the anterior notch in each radial segment of the calcareous ring of the species, SEMPER [42, p. 53] remarked that it is situated “auf einer Seite” in each of the paired radial segments, but in the midventral segment so as to divide this into two equal halves. But for my specimens of Ps. africanus I have found OSTERGREN’s statements as regards the anterior notches in his Ps. mixta [86, p. 5] to hold true in essential points. The anterior end of each radial segment of the calcareous ring is divided by a deep notch, through which the radial canal and nerve pass, into two unequal halves, one broader than the other (textfig. 4). Again, each of the two halves has on its anterior margin a slight: incision or THE SYSTEM OF PHYLLOPHORIN ZA. 55 notch corresponding to the canals of the smaller tentacles. In the paired radial segments the broader half is always dorsal to the narrower. The unpaired midventral radial segment is congruent in form with the segments of the right side, that is to say, the broader half of it lies to the right of the narrower (textfig. 1). The manner of branching of tentacular canals, as made out from serial sections through pharyngeal mass of several specimens, seems to be as follows :— Each radial canal, or the “main canal” as THÉEL has called it [45, p. 135], gives off alternately four tentacular canals (textfig. 1). The first tentacular canal branches out dorsad in paired radii, and to the right in the midventral radius. The second arises on the opposite side at a point just slightly anterior to the point where the first is given off, directed ventrad in paired radii but to the left in the midventral radius. These two canals run nearly transversely, and approaching the margin of radial segments, open each into an ex- panded part of the tentacular canal by a narrow orifice guarded by the ventilative apparatus or “semilunar valves” in a manner similar to that described for Cucumaria planci (BRANDT) by HEROUARD [15, pp. 580—583]. That expanded part of the canals communicates with the large tentacles (D,, V,, R, and L,), and is interposed between a radial segment and an adjoining interradial segment. The third branch, which is smaller than the two preceding and supplies the medium-sized tentacles (D, and R,), leaves the radial canal a short distance anterior to the point where the second canal branches out. In paired radii this stands dorsal to, and in the midventral radius to the right of, the respective radial canal. The fourth, which is the smallest of the four branches, is given off a very short distance from the third branch on the opposite side. This supplies the smallest tentacles forming the inner circle (V, and L,). The third and the fourth branches run forwards, each with the ventilative apparatus in its course, over the incisions in the anterior margin of 56 HIROSHI OHSHIMA : radial segments. Exceptionally there seems to exist cases in which the branches are given off in a way different from that described above, and that especially with regard to the first and the second branches. ii. Phyllophorus japonicus (v. MARENZELLER), Ph. fragilis, sp. n., and Orcula hypsipyrga v. MARENZELLER. All these three species have twenty tentacles, which agree well with same of Pseudocucumis africanus in size and arrangement. In them, as in Ps. mixta, the radial segments of calcareous ring shew on the axial surface slight depressions corresponding to the course of tentacular canals. The branching of these canals takes place in closely similar way as in Ps. africanus, so that a detailed description seems unnecessary. Only it may be noted that in PA. japonicus the anterior margin of each radial calcareous segment is divided into two halves which are subequal or slightly unequal in breadth (textfig. By a): ili. Pseudocucumis japonicus (BELL). Of this species BEDFORD [4, p. 844, figs. II, A—b] has given diagrams showing size and arrangement of tentacles in the two original specimens. Should the blank spaces in his figure II, A—— the one in the midventral and the other in the left ventral radius be filled up each with a large tentacle, that figure will be made to greatly resemble the diagram I have given below (textfig. 2). Of the several specimens of the species examined by me, all had twenty-five tentacles, except a single abnormal case with twenty-six of them. The large tentacles, ten in number, are disposed inter- radially in five pairs (textfig. 2, D,, Vj, R, and L,), with which alternate singly standing medium-sized tentacles numbering five in all (D, and R,). The remaining ten small tentacles are arranged in five radially situated pairs (V2, D., L, and R;), forming an inner circle to that of the other fifteen. The only difference from the previous cases. of species with twenty tentacles, lies in the addition of five small 57 VA. h PHYLLOPHORI THE SYSTEM OF ‘yeuvds-du0}S 's ‘euro TUMIMO 4 ‘opisoA utIPOg do lpea enusapıu YP TeyusA JUSU 97 ‘esiop ys Gy eyusa yoy 17 TESIOP JO 77 :Smipenout msıoppiun (7 = *paquasaadox you Sspeuto awjnseyus ur snyemwdde oayepyuoA ‘uorisod pur ozs AMPI ur pojuasordor SIpVJUIT, “Bult SNOMIVIILO JO SJUOUIS9S jerpr.ı puryoq uoppru 21U (Su UexOAq YIM poumno) speuwd jeıprı OU} yey} OS ‘APIOLIDZUL pulysq wor Bult oy} yw soo] Hug “AT [erpva podurum pur usdo qno st (payop) Suri snooïvoqeD ‘(2 ‘8y) s72221090/ ‘Sf pur (1 By) 5722/022.4/0 smunsnsopnas,T Ut SUA SNOTILOILO Pur sopvzuo} JO woysk [euro 04) Surmoys SLUTISTI(T AW u (4 GU Wy (eae 7 SDUTXON 58 HIROSHI OHSHIMA : tentacles (D,, R,) to the inner circle, a new small tentacle appearing close to each of the five medium-sized ones, in paired radii dorsally to, and in the midventral radius to the right of, the old small tentacle (V, or L,). The anterior part of radial calcareous segments shows some features different from those of the preceding species. A deep indentation divides the anterior edge into two; unequal or asym- metrical halves much as in Ps. africanus (textfig. 2). The two halves have obliquely slanting edge and each of them shows a slight notch. On the larger half, close to the deep median indentation, there is again another small notch (textfig. 3, a). It can be plainly made out from sections that each tentacle is supplied with the five tentacular canals branching from the radial canal in an alternate arrangement. Aside from the presence of a fifth distalmost branch in each radius, the tentacular canals arise in a way similar to that in the twenty-tentacled species mentioned above. The small distalmost branch, which communicates with the fifth small tentacle, arises, in paired radii dorsally from, and in midventral radius to the right of, each radial canal. The smallest notch on the larger half of the divided margin of each radial calcareous segment stands in relation with the small distalmost tentacular canal just > referred to (textfig. 2, D, and R,). 2. Observations on previous records regarding tentaculation, The size and arrangement of tentacles in Pseudocucumis acicula (SEMPER), Ps. africanus, Ps. japonicus, Phyllophorus dearmatus DENDY & HINDLE and Ph. holothurioides LUDWIG have been diagrammatically figured by previous authors, as LUDWIG [20, Taf, VL, Figg. 17,23; 24; Lat’ XV, Kis: ros and 26 peo isdn 12], BEDFORD [4, p. 844, figs. I—III], and DENDY & HINDLE [9, p. 104, fig. A]. But none of them have given an account of the THE SYSTEM OF PHYLLOPHORINÆ. 59% internal organization with reference to the arrangement of tentacless As to ‘the relation between the notches of radial calcareous: segments and tentacular canals, SEMPER [42, p. 67] has stated for his Zhyonidium cebuense (=Phyllophorus cebuensis) as follows :—,, Der: Zwischenriumen zwischen den radialen und interradialen Gliedern: entsprechen die grossen Tentakel, die kleineren stehen auf kleinen - Einschnitten der radialen Glieder, welche einen 3. Ausschnitt für das Radiärgefäss und den Nerv zwischen sich fassen.“ More precise statements about the relations between tentacular arrangement, the canals and the anterior notches of radial calcareous segments are found in ÖSTERGREN’s work [36, p. 4 with Fig. 1]. According to. him, in Pseudocucumis mixta, the canals which join the two smaller tentacles in each radius, pass over slight notches on the two unequal! processes of the radial segment. Though no mention is made as to the mode of branching of the four tentacular canals, it can be clearly seen from his figure that each radial canal gives off four tentacular canals in a regularly alternate manner on both sides, and that the smallest branch is given off last and goes over the narrower process of radial segments. Further, the same author has tried to show: from LupwIc’s figure of the calcareous ring of Orcula tenera [26, Taf. VI, Fig. 17]* that the five small tentacles, which we see in twenty-tentacled forms, are there totally absent, and that the narrower half of the radial segment is pointed at the anterior end, instead of being notched. The third tentacular canal which stands in connection with each of the five small tentacles, is given off from the radial canal dorsally in paired radii, and to the right in the midventral radius. If we carefully look into the numerous figures given by various authors of the calcareous ring of polychirotous Cucumarids, it will be found that the statements of OSTERGREN for Pseudocucumis and Orcula with regard to the relation between the * See also Lupwia 25, p. 813, and Taf. XXX., Fig. 20. 60 i HIROSHI OHSHIMA : anterior notches and tentacular canals are equally applicable for some other species, as f. i. Pseudocucumis acicula [LUDWIG 20, Taf. VI, Fig. 17], Phyllophorus cebuensis [THEEL 46, PI. IX., fig. 4; LUDWIG 26, Taf. VI., Fig. 10], Ph. frauenfeldi LUDWIG [20, Taf. VI, Fig. 22], Ph, holothurioides [LUDWIG 20, Fig. 23], and PA. celer KOEHLER et VANEY [17, PI. I., fig. 24]. Judging from SLUITER’s figure of the calcareous ring of his Orcula purpureo-punctata [44, Taf. VI, Fig. 15], which clearly shows the presence of three notches in each radial segment, it seems highly probable that in that form there exist twenty tentacles, of which five were probably overlooked on account ef their very small size. Also LUDWIG’s statement [25, p. 814] that the anterior part of the calcareous ring of his Phyllophorus brocki is exactly similar in form to that in Orcula tenera, leaves room for suspecting if he has not overlooked a small notch at top of the narrower process of radial segment. Here it may be stated that in the Molpadiida the fifteen tentacles present are usually given off in the same manner as in Orcula. LUDWIG [28, p. 590] has stated in his work on Ankyroderma anusculus (RISSO) that the branching of tentacular canals stands in intimate relation to the form of calcareous ring. Each radial canal should give off three tentacular canals in an alternate manner, and in paired radii the first and the third are always dorsally directed. The midventral radial canal should usually send out the first and the third tentacular canal to the right, but occasionally to the left. GEROULD [14, pp. 161—162] came to the same conclusion from his examination of Caudina arenata (GOULD). LUDWIG [26, pp. 87—88] and OSTERGREN [86, p. 4 and 87, p. 208] took the above branching mode as valid in all the forms of the family. CLARK [8, p. 137] has stated that “there are not three (tentacles) in each interradius, as might be supposed, but four in the middorsal interradius, three in each of the latero-dorsal interradii, three in one of the ventral änterradii, and two in the other.” THE SYSTEM OF PHYLLOPHORIN AS. 61 EDWARDS’ statement concerning Holothuria floridana POURTALES [11, p. 251] seems to be suggestive of the fact that in twenty-tentacled Holothurids a supernumerary and the last acquired tentacle stands usually dorsal to the radial canal: thus, he says: “In the 7 cases with more than the normal 20 tentacles there appears a slight tendency to the addition of extra tentacles dorsally.” 3. General consideration regarding the multiplication of tentacles. On the basis of the data given above, it seems not unwarranted to conclude that the multiplication of tentacles takes place, at least in the group of the polychirotous Cucumarids, according to a general plan, as follows :— All the tentacular canals spring from the radial canal separately and alternately on both sides. In paired radii the first or the proximalmost tentacular canal branches out from the radial canal on the dorsal side; the second stands opposite to the first, 2. e. on the ventral side; the third is again on the same side as the first, and so on. In the midventral radius the canals usually branch out in a way congruent with those in radii of the right side, z. e. the first, the third, efc. are on the right, while the second, the fourth, etc. are on the left side. The more distal the branching point, the smaller is the diameter of the canal and the size of the tentacle it belongs to, and the nearer is the position of the tentacle to the median line of radius. ei For the sake of convenience, the tentacles to which the first and second tentacular canals belong, may be called tentacles of the first order, and those in relation with the third and fourth canals, tentacles of the second order, and so on. Thus, when a certain Cucumarid is said to have tentacles of the first and second orders only, it denotes that there exist either fifteen or twenty tentacles in that form. The so-called . “ decachirotous” forms, such as Cucumaria and Thyone, 62 “HIROSHI OHSHIMA : have tentacles of the first order only;'"the first and ‘second’ tentacular canals on each radial canal branching out exactly opposite to each other. Here I may ‘add a remark* ‘with ıegard to Pseudocucumis intercedens LAMPERT, the only species with thirty tentacles among the Dendrochirotes: According to LUDWIG [23, p. 26], twenty of the tentacles are larger. than the remaining ten, which form an inner circle and stand in pairs, the pairs. recurring regularly at intervals of every four large tentacles. I am strongly inclined to think that the above enunciation is applicable to this case also. I assume that here each radial canal gives rise to Six tentacular canals, 7. e., one in addition to the five tentacular canals to each radial canal of twenty-five-tentacled forms such as Ps. japonicus (textfig. 2). That additional tentacular canal is probably the distalmost or the sixth branch arising from radial canal next after, and on the opposite of, the fifth. Should this be the case, it might be expected that there exists, in each radial calcareous segment (23, Taf. I, Fig. 2], a small notch on each of the two processes forming between themselves the deep median indentation. 4, Order of appearance of tentacles in ontogeny. LUDWIG [80] appears to be the only author who has given any attention to the development of tentacles in polychirotous Cucumarids. For Phyllophorus urna GRUBE, he briefly stated that, so far as the first seven tentacles are concerned, the order of their appearance is similar to that he had observed in Cucumaria planct (27, pp. 183—184].* In the latter species he discovered that ,,die beiden Fühler der beiden ventralen Interradien ihre Wasserkanäle vom mittleren ventralen Radialkanal erhalten, während der Fühler des mittleren dorsalen, sowie derjenige des linken dorsalen Interradius * See also diagrams given by BEcHER 2, Taf. XXXVI., Fig. 43 or 3, p. 407, Fig. Da THE SYSTEM OF PHYLLOPHORIN ©. 63 vom linken dorsalen Radialkanal und endlich der Fühler des rechten dorsalen Interradius vom rechten dorsalen Radialkanal versorgt werden.“ *...., Der sechste und .siebenté‘* continues the author, „liegen in Bezug auf die Medianebene der Holothurie einander genau gegenüber und erhalten ihre Wasserkanäle von denjenigen beiden Radialkanälen, welche sich bisdahin an der Abgabe von Fühlerkanälen überhaupt noch nicht betheiligt hatten, nämlich von dem linken ventralen und dem rechten ventralen.“.>::, „Beide : Radialkanäle entsenden den neuen Fühlerkanal in dorsaler Richtung, also in den linken, - bez. rechten ‘dorsalen : Interradius.“ The pairs of primary tentacles, given off from the left dorsal and the midventral radial canal, are each made up. of exactly opposite and equal-sized tentacles ; therefore it can not be determined whether these appeared simultaneously or not, and if the latter be the case, which appeared first. At any rate, from the fact that the right dorsal radial canal gives off the first tentacular canal ventrally, it may be inferred- that the order of appearance of tentacular- canals does not correspond with their manner of. branching’ in the adult. Of great interest.is EDWARDS’ observation [12, pp. 216—220] on Holothuria floridana that, in each radius, the tentacle which corres- ponds to the first in polychirotous forms invariably. appears first, while that corresponding to. the fourth appears last. Moreover, the order .of appearance. of the four tentacular canals from the midventral radial canal is exactly in agreement with the branching order seen in Pseudocucumis. africanus. 5.

The characters made: use of for distinguishing genera and species * Strangely enough a quite contradictory statement was made by the. same: author at another place, to the effect that the right dorsal radial canal gives off a tentacular canal » nur an seiner dorsalen Seite“ [27, p. 608]. 64 HIROSHI OHSHIMA : of the Cucumariidz have hitherto been principally the number, size and arrangement of tentacles, the distribution of pedicels and papilla, and the structure of calcareous deposits in the perisome as well as of the calcareous ring. The presence or absence of the posterior prolongations in radial calcareous segments seems to be scarcely of more than specific import, though their presence in association with the prolonged “main canals”? seems to be very frequent in the sporadipodous forms, such as Zhyone and Phyllophorus. I should think the construction plan of calcareous deposits in perisome may be of use for the distinction of genera or subgenera; however, we have as yet, as OSTERGREN has said [37, p. 212], no sufficient data in that regard to avail of. That the anterior notches in the radial calcareous segments are in close relation with the number, size and arrangement of tentacles, was first pointed out to be of importance in classification by OSTERGREN [86, p. 5]. As a result of my studies I have come to see that, at least within the subfamily Phyllophorinæ, the ordinal rank of the tentacles present—not a mere statement of their number—taken in conjunction with the anterior notches in the radial calcareous segments, is of greater importance than the distribution of pedicels and papillz in distinguishing genera. The distribution of pedicels and papillz often varies very much according to individuals or to age in one and the same species. Both the genera Semperia LAMPERT and Ocnus FORBES present in that respect no distinct demarcation against the genus Czcumaria, and therefore must be included in the latter [LUDWIG, 26, p. 345]. HEROUARD [16, p. 9] has shown that young Cucumaria mendax THEEL has five rows of pedicels, as is said to be characteristic of Ocnus, but older jindividuals of that species resemble Semperia in that they possess additional pedicels scattered in a few number on interambulacra. 25.

Durch Reisenden wurden freilich zu verschiedenen Museen einige sporadische Stücke heimgebracht, aber mit einer einzigen Aus- nahme wurden sie nicht beschrieben. Auch muss zugestanden werden, dass die Beschreibung von einer Imago hie, und einem Soldaten da, von wenig Interesse war, und den Termitenforschern wenig anziehend sein könnte. Seitdem aber nun die japanischen Forscher sich selbst der Erforschung ihrer Fauna gewidmet haben, ist es ja zu erwarten, dass sie mit gewöhnlicher Gründlichheit und Eifer die Kenntniss des Tierweltes ihres Landes erforschen werden. In termitologischer Hin- sicht ist nun diese Erforschung begonnen, und WATASE und HOZAWA * The specimens of the Japanese termites, which formed the material for Prof. Holmgren’s present paper, had been sent from the Zoological Institute of the Imperial University of Tokio. Prof. Holmgren’s more detailed report on the Japanese termities will be incorporated in his forthcoming Monographie der Termiten des orientalischen Regions. As Prof. Holmgren points out, the species of the Japanese termites known to the natur- alists of Europe and America have thus far been extremely Dante only two in fact. His present paper brings them up to twelve. In justice to the Japanese naturalists, how ever, it must not be supposed that they have been indifferent to the rich termite fauna of the country. In fact, the termites have been made the subject of much study within recent years in this country, chiefly in view of the fact that some of the species do extensive injury to wooden structures. Neither their systematics have been neglected on their part. Written in the Japanese language, however, with no organization at present, whereby the contents of such produc- tions are made intelligible to the workers of the western world, it is not to be expected that such works reach very far, unless the authors took the trouble of translating them themselves, which in the case of the Japanese termite literature, had never been done. Although further details may be expected in his forthcoming monograph of the Oriental termites, Prof. Holmgren’s present paper on the termites of Japan will be of much value to all workers who are interested in the same subject, and to those who take interest in the problem of zoogeography for this part of the world.— S.

The details for the above view will be presented elsewhere, but I am inclined to think that the new termite Zodotermopsis japonicus, instead of being a representative of the northern species, must be considered as a distinct southern element. I am the more disposed to take this view, since the species most nearly allied to it is found in Tonkin, as Prof. Holmgren informs us.—S. WAT ASÉ.

Bemerkung : Hodotermopsis japonicus steht FA. Sjöstedti aus Tonkin sehr nahe und ist vielleicht nur eine Rasse von dieser Art und unterscheidet sich hauptsächlich an der kleineren Statur. Morpholo- gisch stimmen die beide Arten beinahe vollständig überein. Nur der erste Zahn der linken Oberkiefer ist verschieden, indem er bei 7. Japonicus eine kurze vordere und eine hintere (sehr) scharfe Spitze be- sitzt. Bei A. Sjöstedti ist dieser Zahn aber einfach zweilappig mit stumpfen Lappen. Hodotermopsis Sjöstedti ist in meinen Termitenstudien II. photo- graphisch abgebildet, und diese Abbildung giebt auch eine gute Vor- stellung von Hf. japonicus. 114 NILS HOLMGREN : Subfam.

Die ergatoide Gesch- lechtstiere sind besonders im Bau der Antennen verschieden, indem diese bei Arr. japonicus in der Regel in der Mitte etwas verdickt und nur 16-19-gliedrig sind, wahrend jene bis 22-gliedrige Antennen besitzt. Ferner sind das Mesonotum und Metanotum bei Arr. canalifrons viel breiter als bei Arr. japonicus und besitzen grossen Fliigelscheiden. Bei Arrhinoterines sind die Fliigelscheiden der Nymphen hinten mit ihren Spitzen verwachsen, ein Verhältnis, das sonst, wie ich weiss, nur bei Serritermes vorkommt. Arrhinotermes flavus BUGN. aus Ceylon ist durch Grösse und Färbung bedeutend verschieden. Hingegen steht Arr. ¢xopinatus SILV. aus den Samoa-Inseln ziemlich nahe. Mein Material scheint anzudeuten, dass Entwicklung von ergatoi- den Geschlechtstieren aus wenigstens älteren Larvenstadien möglich wäre. Interessant wäre es, wenn man die larvale Entwicklung dieser Art auf einen grossen Material studieren konnte. Ich glaube, dass eine solche Untersuchung recht viel neues und überraschenden darbieten würde. Subfam. Leucotermitinæ HOLMGR. Gattung Leucotermes SILV. Leucotermes speratus (KOLBE.)

Er gehört sonst der Gruppe von dunkelgefärbten Zexcozermes-Arten, welche nur in relativ nördlichen Klima vorkommen. Hierzu gehören ausserdem: Z. lucifugus Ross, Z. flavipes KOLLAR und Z. virginicus BANKS, welche alle vorliegen. Zur Unterscheidung dieser Arten teile ich hier ein Schema mit. Imagines. A.

E. lucifugus ROSSI Wie aus dieser Ubersicht hervorgeht, sind die Soldaten dieser vier Arten einander äusserst ähnlich, und die Unterscheidung der- selben, ohne zugehörigen Imagines, muss deshalb als sehr misslich be- trachtet werden. Angaben von Funden von Soldaten, wo Imagines nicht gleichzeitig vorhanden sind, z. B. von ZL. flavipes ausserhalb Amerika z. B. in Japan, miissen deshalb als recht zweifelhaft ange- sehen werden. ” In den obigen Übersichten fehlt “ Leucotermes vilis (HAV.),” eine Art, welche ich, DESNEUX folgend und ohne eigene Kenntnis, als ein Leucotermes aufgefasst habe. Nach dem ich aber nun Exemplare dieser Termite untersucht habe, finde ich, dass sie gar keine Zexco- termes-Art ist. ‘* Termes vilis HAV.” steht “ Eutermes desertorum DESN.” aus Afrika am nächsten und repräsentiert wahrscheinlich eine neue Gattung, welche in der Nähe von Hamitermes SILV. steht.

Bemerkung: Betreffs der Imagines ist diese Art mit O. dives, O. javanicus, n. sp., O. Buitenzorgi am nächsten verwandt. Von O. dives unterscheiden sie sich leicht an der haarigen Stirn. O. javanicus ist nur wenig verschieden. Der geibe Vorderteil des Transversalbandes (bei O. formosanus sind nur die Vorderecken hell gelb), die wenig erhabenen Innenränder der Ocellen und die nicht flachgedrückte Stirn unterscheidet O. javanicus von O. formosanus. Ebenso ist O. formosanus viel dunkler gefärbt mit schwarzbraunen Flügeln. O. Buttenzorgi besitzt in den grossen Mandibelkondylen eine Eigenschaft, welche sie von O. formosanus sofort unterscheidet. Von O. assamensis, dessen Soldaten und Arbeiter kaum von ©. formosanus unterschieden werden können, ist O. formosanus als Imago sehr verschieden. O. assamensis (Imago) ist viel grösser (Breite des Kopfes 2.76 mm., Breite des Pronotums 2.62 mm.). Die Ocellen liegen bei O. assamensis nur um ihren kürzeren Durchinesser von den Augen entfernt (bei formosanus sind die Ocellen viel weiter von den Augen getrennt). O. formosanus ist vier dunkler gefärbt. Die Soldaten und Arbeiter von O. formosanus sind von denjenigen von O. assamensis kaum verschieden und erinner uns auch sehr an O. obesus und O.

By Seinosuke Uchida Ornithologist to the Bureau of Agriculture, Tokyo. The following list was originally compiled for my own use in the study of Formosan avifauna. On recommendation of Professor Ijima, it is now published with the aim of giving a handy guide to the collectors and students of the birds of that interesting island, and eventually of aiding in the furtherance of our knowledge about them. It scarcely needs to be mentioned that the list is largely based om the previous records, but I should state that not a small part of my labour consisted in the study of the collections of the Science College, Tokyo Imperial University, and of the Taihoku Museum, Formosa. It may here be mentioned that the Science College collec- tion of Formosan birds, which originally consisted of the skins obtained by Mr. Tada in 1896-1897, has of recent years undergone much augmentation from donations by Mr. A. Owston of Yokohama and by Mr. Y. Kikuchi of the Taihoku Museum. In the last published important work on Formosan birds—that . of Ogilvie Grant and La Touche (1c07)—there were given 260 species as known from the island. Overlooked in that work but previously re- ported from the island were 5 species (viz., Bulweria bulweri men- tioned by Ogawa 1906; Cuculus canorus, Tringa subarquata, Nycti- corax prasinosceles and Larus vegæ contained in Tada 1898); while subsequently new additions were made: by Grant (1908) 3 species (viz., Pyrrhula owstoni, Hemichelidon ferruginea and Syrnium nivicola) and by Hartert (1995) 1 species (viz., Alauda coelivoa). Now 138 S. UCHIDA : in the present list, still 21 more are added,—all which I have indicated in the list by affixing asterisk to the names— bringing the total number of bird species known from that island up to 290. So far as I can judge, none of the added species are new, but are forms that have been known from either the adjacent parts of the continent or from neighbouring islands on the north or south. The discovery of Zicœum sp. has introduced a new family, the Dicaidae, to the ornis of the island. Japanese names proposed for the first time in this paper are also marked with asterisk. A list of the literature relating to Formosan birds is appended below. I. KR. Swinhoe: Further corrections and additions to the “Or- nithology of Amoy,"” with some remarks on the birds of Formosa.

Pac 215 221 225 eee) 239 355 Notes on the Spermatogenesis of the Wild and the Domesticated Silkworms. By Naohide Yatsu. Although the spermatogenesis of some lepidoptera has been lately studied with especial reference to the chromosomes by the late Miss STEVENS (’05), MUNSON (’06), Miss DEDERER (’07) and. Miss Cook (10), yet that of the silkworm has not been undertaken since the apperance of TOYAMA’S papers (’94 a and b). What one finds in the later literature regarding the germ-cells of the silkworm is limited to fragmentary notes by LA VALETTE ST. GEORGE (’97), HEN- NEGUY (’98) and MEVES (’03) on structures other than the chromo- somes. Such paucity of works on the spermatogenesis of the silk- worm is rather remarkable, since in most countries the material can be obtained without difficulty. As there are quite a number of varieties in the domesticated silkworm, I thought that they would be an excellent object for the study of correlation between their morphological features and the chromosomal characters. So I undertook a comparative study of spermatogenesis of the wild silkworm (Zheophila mandriana) and of the following seventcen varicties of the domesticated silkworm (Bombyx mori) : Dainyorai Aojiku Koishimaru Araya Japanese races. Watako Seihaku Shirojima x Kurojima Kasasagi SO OR OR ER a Corean No. 1 (dark brown) Corean races. Corean No. I (green) 9 216 N. VATSU? II, Shin-en 12. Ryükaku 13. Birodo 14. Chinese 15. Bagdad } Turkish races. 16. Bas-Alps 17. Italian No I Chinese races. European races. As fixing fluids acetic-sublimate and FLEMMING’S solution were used. The latter preserves excellently both the cilia and the V- shaped centrioles of the primary spermatocyte, which were described and figured by MEVES (’97) and HENNEGUY (’98). It is interesting to note that the testes of all the yellow cocoon races are yellow as are also their silk-glands and body-fluid. In those races, moreover, the testes grow slower than in the white cocoon races, so that the larvae of the former yield testes of suitable stages for the study, when they have grown to a size much larger than those of the latter. I experienced some difficulty in getting the materal of the wild silkworm. long as the egg-cells remain in the earlier stages of growth and are still attached to the gonad- wall, no spermatid or spermatozoon is yet formed and the male ele- ments are represented by a few small masses of spermatogonia or spermatocytes, nearly all of which show division-figures. Of course these cell-masses still lie in the epithelium, mostly in close vicinity of the funnel-shaped mouth of the genital duct. In the eggs, the later phases, during which they reach maximum size and are brought to complete maturity ready for deposition, are indicated: first, by their liberation from the gonad-wall; secondly, by rearrangement of nucleoli from a localized disposition with tendency to accumulate at the ventralmost corner of the germinal vesicle, into a regular periphe- ral destribution ; thirdly, by the development of the two egg-membranes. Nearly simultaneously with, or a little prior to, the processes mentioned above, the spermatids make their first appearance, subse- quently to undergo metamorphosis. This metamorphosis takes place in some parts of a gonad a little earlier than the liberation of the eggs, so that in many gonads there are to be seen fully formed free spermatozoa in accompany with eggs which have not yet reached the final maturation-stage. Nevertheless, the interval between the maturing of the male and female elements is never so long as to cause protand- ric hermaphroditism like that of Sf. e/hardt. So much for the more important characters of the present species as seen from the systematic point of view. A brief discussion will now follow regarding its systematic relations to the allied forms known. It will not be necessary to enter into a historical or critical review of fresh-water nemertines, as this has already been thoroughly done by Silliman” and more recently by Montgomery (1895) and Bòhmig (1898). Setting aside for the present the question of the validity or non-validity of the several species that have hitherto been 1) Silliman, W.A., Beobachtungen über Süsswasserturbellarien Nord-Amerikas. Zeit- schr. f. Wiss. Zool., Bd. 41, 1885, 246 I. IKEDA: described by the authors, we will here consider the more important question whether all the known fresh-water nemertines should proper- ly be regarded, as Bürger” does, to constitute the single genus Tetrastemma, or, as Montgomery and Böhmig believe, to belong to two genera Zé/rastemma and Stichostemma. The genus Stichostemma was first established by Montgomery in 1895, when he described a new fresh-water nemertine from Berlin (Stichostemma eilhardi). A year later, the same writer? described another new species (Sf. asensoriatum), belonging to the same genus. In 1898 Böhmig redescribed his former TZetrastemma gracense as the third species of Stichostemma (St. gracense). The grounds for erecting that new genus were given by Montgomery” in 1897, and the distinc- tion he makes between Zétrastemma and Stichostemma, which two genera cover all the known fresh-water nemertines, will be clear from a compari- son of the diagnoses given by him toeach. For Stichostemma he gives: “ Eyes variable in number, usually more than 4; 9 nerves in the proboscis ; rhynchocæl does not extend to the posterior end of the body ; nephridia extending from in front of the brain to the posterior end of the body ; protandric, hermaphroditic, oviparous.” And for Zetrastemma: “Eyes not variable in number, either 4 single eyes (the rule), or 4 double eyes (7: falsum, cructatum); 10 nerves in the proboscis ; rhynchocal extends to the posterior end of the body; nephridia not extending posteriorly behind the cesophagus, dicecious, oviparous.” Despite Biirger’s disapproval (1895 and 1904) of establishing the the new genus Sfichostemma, Böhmig adopted Montgomery's view in consideration of important differences between the two genera in 1) Birger, O,, Die Nemertinen des Golfes von Neapel #/c F. u. FI. d. Golfes von Neapel, 1895. And also in “Das Thierreich,” 1994. 2) Montgomery, T.II., Stichostemma asensoriatum n. sp., a Fresh-water Nemertean of Pennsylvania. Zool.

A NEW FRESH-WATER NEMERTINE. 247 question with regard to their excretory organ, their rhynchocoel, and very probably, to their rhyncho-stomodæum and hermaphroditism as well. However, upon finding some incongruous points in Montgomery’s definition of Schostemma when applied to the two species, Sf. asen- soriatum and gracense, Bohmig (1898) has revised the generic dia- gnosis as follows: “ Augenzahl veränderlich, gewöhnlich mehr als 4;9 oder 10 Rüsselnerven ; das Rhynchocoelom erstreckt sich nicht bis an das Körperende ; die Nephridien dehnen sich von der Gegend des Gehirns bis zur hinteren Körperspitze ; zwitterig, ovipar.” I take this definition of Stichostemma to be excellently drawn up, sharply differentiating, as it does, that genus from the other. No emendation to it is made necessary by the discovery of the new species described in this paper. On the following page is given a tabular list of the more important characters of the three hitherto known species and of the present new species of Stichostemma. A glance at that table will show that the present species is more closely related to Sf. ec/hardi than to any other of the species, and that Sr. asensoriatum takes an isolated position in that it lacks the frontal organ and is provided with an indefinite number of eyes. The relation between the present species and Sf. gracense, in spite of several points of agreement in internal anatomy, seems to be comparatively remote, since the two species differ markedly from each other in size and colour of body, in the presence or absence of senso- ry spines, in the extent of cephalic glands, etc. With respect to the last-named organ, the present species bears a singular resemblance to the otherwise remotely allied member, Sf asensoriatum. It is also a noticeable fact that the present species shows, as regards the number of proboscis-nerves, an intermediate or transitional relation to the three other species. As already stated in the foregoing description, the said nerves number g or 10 in the present species, the variation IKEDA : I. 248 “AT snosur} mus uadit syusw sole eet ‘2HIPUTIOIT "DHPUTIOIT ‘A -snoauejmuis uadır Sp -X2S Jor aus np -or1ydrursazy ‘odu Im ‘9pis yora uo 03 DOG: ‘sofa jo urd puosas ou} Jo paar ol puofaq Sut -pu2]x9 jou A|10119}80, *podopaaap PILA ‘oI 10 6 ‘OI ‘adi qe ‘ penprAIpur UMOID [[N} v ur apis yore uo zh coda wa} 30 QI ‘ penpiAIpur qs93.1e] 94} Ur apis yore uo SE yncqy ‘spruor) ‘UILIq ou} 0] Suiuovat 4] -xvau ‘pado] -2A9p TEA ‘umag 94} oO} Suiyova.t ‘A[IOLI0} -sod padojaa pP TPA\ ‚spurjd oyeydag “Suu M "QUO, CS SQUITMQUIOS ‘9 Aysoyy ‘Sugue An ‘Suryure M *JUISOI "soa TOU -SIOSOQOIT "244 ‘sourds K1osusg *yuasaty “DUNUTA\ *quaso1g ‘JUISAUT *uv8.10 ejuo.] "Pal YSIMOoT PA 3431 “au SE *‘aSunIo jus ur "zu QT "SIPUDAS "0S ‘ULNJDIAOSUISV DIS *MOI2 USIPpoM una VI ‘UMO1Iq Usippex 07 UAOIq -YSI MOTO A ‘UU TI ‘J8u9t-4p0q *1n0]o 109 wnwıxeW 240120 = *3SUIIVALT ‘45 A NEW FRESH-WATER NEMERTINE. 249 being apparently entirely idiosyncratic. It is, of course, a well known fact that the number of proboscis-nerves is in many other groups of nemertines variable to some extent even in one and the same species ; consequently, it cannot be much utilized for systematic purp se. This seems however not to apply to the three hitherto known species of Stichostemma, in which the number is definitely known to be either g or 10. This fact has induced me to regard the indefiniteness in the number of proboscis-nerves in the present species as one point of its specific peculiarities. Lastly, the remarkably large size of the present species deserves special mention, as this seems to be correlated with several important characters of the species, for instance, with the unusually large number of mature gonads, with the comparatively short extent of the rhynchoccel, efc. From what I have described in a previous para- graph, it will readily be seen that the characteristic points just referred to undergo more or less remarkable changes, according to certain stages of growth, even after the animals have actually entered into sexual maturity. While the maturing gonads increase in number as the animals grow larger, the cephalic glands and the rhydchocoel tend to become reduced in their relative range of extent. So that, if the worms in widely different stages of growth be obtained from different localities, it would be more or less puzzling to determine whether or not they should be brought under the same species. It is interesting to notice that the four species, if arranged in the order cf their body- lengths, as they are in the foregoing table, seem to show between them certain relations similar to those which I have pointed out in the present species with reference to different stages of its individual growth on the one hand, and the number of mature gonads and the relative extent of cephalic glands on the other. If this idea be cor- rect, an explanation suggests itself why the two such remotely related species as S7. asensoriatum and the present species show the singular agreement in having cephalic grands of a similarly low develop- 250 I. IKEDA: ment. I think it highly probable that the relative extent of rhynchocoel in the four specie; also varies inversely with the s'ze of each; that is, it should be of the largest extent in the smallest form, and vice versa. But this can not certainly be insisted upon without exact measurements of the organ in all the known species. The Life-habits. As to the original habitat of the plant, Lysichiton kamtschatense, I have made some inquiries, in view of the possibility that the animals were transported together with the plant from somewhere to the garden. But I could receive no satisfactory information, except that the plant is a form indigenous in Hokkaido as well as in some parts in the north of the Main Island or Honshù. Anyway, it seems certain that this Japanese species of Siichostemma belongs to the temperate-subarctic fauna as do also all the known species (S¢. ez/- hardi from Berlin, Sé asensoriatum from Pennsylvania, and Sz. gracense from Gratz). As to the life-habit of the species in the plant-vessel, they were always found buried 1-2 cm. deep in the very soft mud and almost always in a contracted state within the mucous secreta,—never found creeping on the bottom, nor swimming in the water. The worms showed a fairly strong tendency to negative heliotropism, so that, when kept in a small vessel, they crept about on the surface of mud during night or early in the morning, but went underneath the mud when bright sun-shine pervaded the room. They are more or less gregarious, as often observed by me in the culture-vessels and in the plant-vessel. Most of the specimens in hand were dug out from among the plant-roots, where they were found crowded together. The negative heliotropic habit of the worms seems to be directly related with the nocturnal spawning. During nearly 70 days, from the 19th of April to the end of June, I have observed twenty or more cases of spawning but never in the day-time. Judging from the fact A NEW FRESH-WATER NEMERTINE. 251 that freshly deposited eggs were found in mornings (6 to 8 a.) al- ways in so early a stage of segmentation as consist of 2 or 4 cells, it may be assumed that the deposition took place before dawn. I should here mention that the eggs segment very slowly, some forty to sixty minutes being required for one complete cell-division in early cleavages. Individuals of a large size lay 400 to 500 eggs in all. The eggs are found sometimes scattered about without order on the bottom of the vessel, and sometimes in a group, as described by Lebedinsky” (1897) for Zétrastemma vermiculus, enclosed in a colourless and transparent jelly-like string 4 to 5 cm. long and about 2 77. thick. This gelatinous, substance, probably mucin in nature, gradually grows more liquid-like with the lapse of time, and finally, within 48 hours, is thrown off by the developing embryos, As far as my observations go, the mother worm perishes sooner or later after spawning. Those individuals which have finished spawning can easily be recognized by their loss of the peculiar yellowish markings which were visible before on the dorsal side, by their dirty brownish red colour, and by their showing un- evenness of body-surface. In spite of my attempts to keep alive such individuals by feeding they invariably broke up into short pieces within one or two days finally to become totally disintegrated. To my regret I could not ascertain if the same or a similar fate befall the precociously mature worms after spawning. Lastly I may be allowed to make a few remarks regarding the segmentation of the eggs. As the segmentation of nemertine eggs is but meagrely known to us, I have endeavoured to study the process with the material in hand and, if possible, to make out the origin of mesoderm-cells. To my regret, shortage of material has compelled 1) Lebedinsky, J., Beobachtung über die Entwicklungsgeschichte der Nemertinen. Archiv. f, Mikr. Anat., Bd., 49, 1897. 252 I. IKEDA: me to give up my studies long before obtaining any hint towards clucidating the question. The segmentation I have been able to follow up only as far as the 64-cell stage, in which no directive cleavage determining the future body-axes has as yet set in. As to the general mode of segmentation, the present case belongs to the perfectly spiral type which prevails in some other nemertines as well as in polyclads, polychaetes, echiuroids and molluscs. The process pro- ceeds to the 28-cell stage in much the same way as was described by E.B. Wilson” for Cerebratulus lacteus and by Zeleny” for Cere- bratulus marginatus, except in the fact that the first dexiotropic cleav- ages giving rise to the 8-sell stage are equal instead of being unequal. In the accompaning table is given the order of cell-division up to the 64-cell stage, 4. and / being used to denote dexiotropic and laeotropic divisions. The sign = denotes equal division; _L or T, unequal division; and JL or TT, markedly unequal division of blasto- meres giving rise to the upper or lower larger cells. As in Arenicola cristata studied by Child,” the rosette cells (14,1 , ec. in textfigs. I and II) are first formed at the 36-cell stage by remarkably unequal lacotropic divisions of the cells 14,, ee, of the 32-cell stage into Ia, and 1@,, efc. The 44-cell stage is reached by two simulta- neous equal and laeotropic divisions of 14», etc. and 1a», etc. of the first quartet into Ida, and Ia», Id, and Ia», etc. etc. (see text figures I and II). After that, the 48-cell stage is brought about by equal and lacotropic divisions of Ia,, e¢c., which correspond to the intermediate cells of polychaete-eggs, into 14, and Id», etc. The cells 14», e¢c. are situated each at the apex of the cross-figure formed by the rosette cells (14,1 e/c.).

IKEDA: the divisions of 2a,, etc. into 2a, and 24», etc., which lead the egg into the 52-cell stage. As this cleavage goes on quite similarly, —e.i. laeotropically—in the four quadrants, there appears no trace of asymmetry to determine the subsequent bilateral symmetry. ne stage consisting of 52 cells is rather transient, since the cells 24, etc. very soon follow, the above cleavage to divide slightly unequally into 24, and 24», etc. The formation of the fourth quartet (4a, etc.) takes place at the 56-cell stage, while the first division in the third quartet (34, efe. into 3a, and 3a,, etc.) occurs at the 60-cell stage, thus giving rise to the 64-cell stage. These cleavages are likewise effected by equal and laeotropic division, and accordingly do not give any determination to the future bilateral symmetry. I have observed some eggs consist- ing of 72 cells. They have probably arisen from the 64-cell stage by dexiotropic division of such cells in the first quartet as Ia, etc. (the rosette) and 1a,» e/c.—the latter corresponding to the stem- cells of the “cross” in polychaete eggs—into 14,1 and 14,» etc, 1a; and 14» efc. But I cannot be certain on this point, since I have not actually detected any division-figures causing the supposed cleavages. To recapitulate, the segmentation-process belongs, as in the case of Cerebratulus lacteus observed by Wilson, to a very regular spiral type and shows in its earlier phases no directive cleavage determin- ing the axes of embryo and the origin of mesoderm. As was pointed out by Wilson in his case, the cross formation takes place in the present case also at least not earlier than in the 72-cell stage. Though I cannot make any definite statement about the origin of the mesoderm, yet it seems almost certain to me that Lebedinsky’s view of the origin of mesodermal bands from four mother-cells does not hold good in the present case. Here, the mesodermal bands are present in a pair as was observed by Wilson also, and are produced by two large cells which lie symmetrically one on each side of, and near the postero- lateral lip of, the gastral invagination.

University, Sapporo, In view of the fact that Myxosporidian parasite has never yet been reported from the gall-bladder of the common carp, I deem it worth while to give the following account of an apparently new Chloromyxum species, which I have discovered in the said organ of that fish. The species I propose to call C. oz, from the Japanese name of the host. During May, 1912. there came under my observation that, of the numerous carps obtained in Sapporo, Hokkaido, and examined by me, many were peculiarly pathologically affected. These showed gall- bladder of an unusually reddish colouration, due to the contents being of that colour; moreover, it was generally found to be much dis- tended, while the wall was changed into so delicate a texture that it easily burst on application of a slight pressure. The peritoneal membrane in the neighbourhood of the organ so aflected frequently presented a somewhat greenish yellow hue, evidently as the result of exudation of the bile. In certain cases a similar colouration was also observable in the external skin of the dorsal body-parts and sometimes even in the iris of the eyes. Now examining the gall-badder of the fish presenting more or less the above icteric symptom, I have always been able to discover peculiar Myxosporidian sporoblasts and spores floating in the contents. I have found that nearly 10% of the carps that were brought to me were infested by the parasite. The characters of the spores indicate that we have here to do with a 258 T. FUJITA. Chloromyxum, which however differs in structural details from any hitherto known species of that genus. The sporoblasts in question are colourless, transparent, and of an approximately spherical shape, up to 50 in greatest diametre (see the accompanying figure). They contain I—3 spores, each situated in a clear space surrounded by a membran- ous envelope, around which there is some finely granular matter. The spores, found either in the sporo- A 2.5, 1905, il, p. 342. Nom. JAP. Yama-inu. NOM. ANG. Japanese wolf. Dist. Hondo (Thomas), China. 135. Canis lupus Linn.

By Arata Terao, Rigakushi. (Zool. Inst., Sci. Coll., Tokyo Imp. Univ.) With 4 textfigures. In the present catalogue are listed 68 species of hermit-crabs so far known from Japan. They are referable to 15 genera. Of the above number of species, four seem to me to be new to science and are here described for the first time, viz., Parapagurus ijimai, Pagurus watasei, Eupagurus gotot, and Diogenes nitidimanus. Of the genera given in this paper, Parapagurus is taken in the broad sense of including Sympagurus Smith under it. In my studies of the group I have had at disposal the entire collection in the Zoological Institute of the Science College, Tokyo Imp. Univ. For the facilities and useful advices given me in that Institute, it is my pleasant duty herewith to return my cordial thanks to Professors Ijima, Watasé and Gotò. My thanks are also due to several other gentlemen who have assisted me in obtaining materials from different parts of the country. I am under special obligation to Professor S. Ikeda of the High School of Kagoshima, by whose inter- mediation I have been able to examine not only the collection of that school but also the specimens belonging to some other public institutions of that city. 356 A.

Clibanarus bimaculatus, Ortmann, Zool. Jahrb., Syst., VI, 1892 pp. 290, 291. Note: A male from Kataura, Prov. Satsuma, in the Sci. Coll. Mus. A striking difference between de Haan’s original description and that specimen lies in the relative size of the chelipeds. From an examination of males, de Haan put down ‘‘ pede antico sinistro in maribus majore,” whereas in the single male specimen on hand the 7797? cheliped is slightly more massive than the /ef. Longitudinal groove not present on dactyli of ambulatory legs, a negative character utilized by Ortmann for one of the points by which this species may be distinguished from CZ. misanthropus. Of the two figures given by de Haan, the one (tab. 50, fig. 4) well represents the species; the other (tab. 49, fig. 7) is not at all referred to in the descriptive text and differs much from the figure just mentioned but greatly resembles Zupagurus samuelis Stimpson in general appearance, Clibanarius corallinus (Milne-Edwards).

The smaller individuals agree in the shape and granulation of left cheliped and in the relative length of eyestalks with 2. spinifrons (de Haan), a form which was regarded by Ortmann to be the young of this species; while in other important characters, f. i., in the spinulose antennal acicles and in the setose dactyli of crawling legs, they tally completely with the description given by de Haan of Pagurus edwardsii. JAPANESE HERMIT-CRABS. 363 Diogens nitidimanus, n. sp. (Textfig. 1). Carapace depressed, broadened posteriorly, well-calcified in front of cervical groove, with several transversely or obliquely directed, close series of setose granules in antero-lateral regions; on each side a longitudinal row of teeth, running for nearly two-thirds the length of cara- pace in front of cervical groove. A short way pos- teriorly from the hind end of the teeth row, there is a small well-calcified areolet which is anteriorly spinulose. Rostrum broad, almost rounded off and indistinct, less prominent than antero-lateral teeth of the anterior border of cara- pace. Textfig. 1. Eyestalks very stout, Diogenes nitidimanus, n. sp. A, anterior half of carapace, x8; B, left cheliped. x6; C, 3rd left leg, slightly narrowed in the X 7. middle, shorter than the an- terior border of carapace, reaching to middle of the last joint of both antennular and antennal penduncles. Eyes occupy about the third distal part of the terminal joint of eyestalks. Ophthalmic scales juxtaposed, large and broad, tipped with one or two spinules. The spine on ophthalmic somite acute, entire, short. Antennal peduncles slightly setose, longer than antennular pedun- cle; antennal} acicles spinulose and slighty setose, shorter than the penultimate joint of antennal peduncle; antennal flagella about as 364 A. TERAO: long as the carapace measured in the median line, provided with stout long bristles on the ventral side; each bristle bearing on the ventral side a series of paired setae growing out vertically. Left cheliped twice as long as the carapace measured in the median line ; the whole cheliped almost hairless except on the dorsal setose surface of merus, and somewhat glossy on surface in spite of the granulation; upper border of hand and carpus well-defined ; all joints elongate ; hand about twice as long as broad, index acute. Right cheliped wanting. Second and third pairs of legs setose, spinulose on the upper border of propodus and carpus; dactylus longer than propodus, with a longitudinal groove on the outer surface. Note: A male specimen from Prov. Sagami is in Mr. R. Saitö’s collection. The species is closely allied to D. granulatus Miers, from which it differs however in the ophthalmic scales being apically spinulose instead of being entire. The present species is also near to D. drevirostris Stimpson, but this differs from it in the carpus of left cheliped being short and of a triangular shape. Diogenes penicillatus Stimpson.

Note: Numerous specimens from Misaki and two females from the Nagasaki Prefecture in the Sci. Coll. Mus. They inhabit gastropod-shell-like colonies of Æydractinia sodalis Stimpson and of 77. spiralis Goto. In all the specimens before me, antennal acicles do not quite reach up to the level of the extremity of eyestalks, while the lezs of the right side extend well beyond the tip of the larger cheliped. In these respects, the specimens may be said to stand not in exact harmony with Stimpson’s description and figure of the species. Eupagurus gotoi, n. sp. (Peston 2): Almost hairless throughout entire body. Carapace depressed, broadened posteriorly, strongly calcified in the pear-shaped area in front of cervical groove, but very thin and almost transparent in the branchial region so that most of the gills can be seen through from the dorsal side of carapace. Rostrum broadly triangular, pointed at tip, slightly carinated, projecting a very short way beyond the level of the antennal angles of carapace; the antennal angle tipped with a minute spinule. Eyestalks moderately large, overlapping the last joint of anten- nular peduncles just at base, slightly curved outward ; eyes scarcely JAPANESE HERMIT-CRABS. 367 dilated, taking up about a fourth part of the terminal joint of eye- stalk ; ophthalmic scales small, lanceolate, deeply concave, distant. a d Antennal acicle curved, slightly setose, nearly as long as the last joint of antennal peduncle and reaching beyond the level of the distal end of eye- stalk ; antennal flagel- lum about two and a half times as long as carapace, almost nude or with but sparsely set minute setae.

TERAO: Left cheliped reaches to base of right palm; the merus spinu- lose along the upper border ; the carpus spinulose along both inner and upper borders; the hand deeply concave, spade-shaped, with a thin marginal ridge, which in the basal part of the propodus covers over the articulation of the latter with the carpus and distally towards the finger-tips becomes gradually obliterated, the ridge on the movable finger running nearly in the median line of its surface. Ambulatory legs of both sides compressed, their tip reaching beyond that of the left but not that of the right cheliped; distinctly spinulose along the upper border of the carpus of the 2nd and 3rd right legs as well as of the 2nd left leg; dactylus longer than propodus, with an inconspicuous longitudinal groove on both outer and inner surfaces, beset with strong bristles along its upper and lower borders. Abdominal appendages, excepting those that form the tail-fan, are only two in number, viz., the 3rd and the sth, both of which are unequally biramous and are situated on the left side, Terga very thin and but little calcified, excepting those of the somites which form the tail-fan. The 4th and 5th terga have each a pair of round convex areas separated from each other by a consider- able space. Colour in spirit: biscuit yellow or brownish yellow, with spots of a paler colour on ambulatory legs, especially on their outer surface. Ncte A male specimen (Mus. No. Cr. 335), preserved in the Imperial Museum at Uyeno, Tokyo; it is from the Aomori Prefecture. The shape of both chelipeds is suggestive of a digging or burrowing habit. The specimen, at the time of my examining it, was smeared with mud, especially on the dorsal concave surface of the left hand. This species can be easily distinguished from the others by its characteristic chelipeds. As already stated, the species is very closely allied to £. cavimanus. Eupagurus gracilipes Stimpson.

Crust., pt. 2, fasc. 1, 1905, pP, 731, pl. x, oma a: Note: To the above species which was described by Stimpson from the North China Sea I refer two male specimens contained in the Sci. Coll. Museum. They were obtained by a trawler in the Nagasaki Prefecture. Both exhibit a pin-hole-like depression on the ventral side of the carpus of each cheliped, and seem to be also referable to Alcock’s E. carpoforaminatus var. nephromma, but not exactly with typical £. carpoforaminatus of the same author. In fact I am greatly inclined to think that the depression has escaped Stimpson’s attention and that £. carpoforaminatus var. nephromma Alcock is identical with his Z. mega/ops. If I am right in this assumption, it follows that Alcock’s typical £. carpoforaminatus should be called Z. megalops var. carpofora- minata, which may be distinguishable from typical £. megalops by having, amongst other points of difference, relatively longer dactyli to second and third pairs cf legs, the dactyli being about twice (instead of about one and a half times) longer than the propodite. The specimens in question, which were at first put into formalin but were after- wards transferred into 70% alcohol, show a faint purplish red colouration on the anterior border of carapace and on the dorsal surface of chelipeds and legs. On the legs this colour tends to occur in the form of cross-bands. On the ventral surface the chelipeds JAPANESE HERMIT-CRABS. 371 and legs are of a nearly uniform ivory white colour. The granules and spinules on chelipeds and legs as also the entire chelae are nearly white. Eupagurus middendorfi (Brandt). Pagurus (Eupagurus) middendorfi, Brandt, Middendorff’s Sibir.

Chelipeds and ambulatory legs thickly beset with thorn-like spines and tufts of bristles, especially in the last three joints and on exten- sor surfaces ; with stronger tooth-like spines along the crest-like inner border of merus and moderately strong spines along the upper inner border of carpus and of the palm of left cheliped. Left cheliped much larger than the right, its length equal to about seven-eighths that of carapace; lower border of palm with a well-defined series of tubercles. Ambulatory legs compressed, those of the left side reaching beyond cheliped of the same side ; those of the right side even longer. Abdominal appendages well-developed in the female. Abdominal spur present. Colour.—In spirit yellowish but reddish towards tip of legs; numerous minute spots of a reddish colour scattered on carapace, legs, and abdominal terga; eyestalks with a broad purplish cross- band ; bristles yellowish. Formalin specimens show punctulation of a darker colour; bristles reddish or brownish red and mostly yellowish distally. Note: The type specimen is a female from Kome-no-tsu, Prov. Satsuma. It is preserved in the Sci. Coll. Mus. Carapace length 32 mm. Further, there are in the same collection two males, one from Proy. Kii and the other from the Nagasaki Prefecture ; a female from Tempözan, Prov. Satsuma, in the collection of the Kagoshima II. Middle School; a male in Mr. R. Saitö's collection ; and finally, a male in the collection of the Tokyo Higher Normal School. This species is Closely allied to Pagurus megistos (Herbst), but differs from it in the shorter eyestalks, in the punctulation being of a reddish instead of a whitish colour, and in the convergently U-shaped suture-line in front of cervical groove. ‘This species is also very near to P. diogenes Fabricius but is distinguishable by the left chela being not so much shortened as in the latter species.

Grust., Spt. ;alasc. 1, 1905, Pros: Note: Smith separated Sympagurus from Parapagurus merely on the ground that while in the former the arrangement of gill-plates is biserial in the latter it is quadriserial However, this distinction can not always be carried out with exactness, since in Sy»1#a- gurus nudus Milne-Edwards it is known that some gills have the plates quadriserially arranged, though those forming the outer series on both sides are rudimentary. The new species, which will soon be described under the name of Parapagurus ijimai, is another example in which the gill-plates are in a way intermediate between being biserial and quadriserial, in that the biserial gill-plates are each bifid at the distal end. Under these circumstances it seems to me advisable to reunite the two genera. Parapagurus diogenes (Whitelegge). Sympagurus diogenes, Whitelegge, Mem. Aust.

JAPANESE HERMIT-CRABS. 385 Gill-plates biserial, each plate bifid at tip, broad. Colour in spirit greenish; eyestalks whitish. The peculiar greenish colour of the body is probably due to the verdigris which was produced by the brass-wire used to keep together the broken feet. The alcohol in which the specimen has been preserved also shows a faintly greenish colour. Note: This new species is based on a male specimen in the S. C. Mus.; it is labelled Oki- nosé, Sagami Sea; 290 fathoms ; May 5th, 1899, Kuma coll. The species is closely allied to P. pi/osimanus, but differs from this in the much broader shape of the eyestalk. It is also near to P. douviert, but is distinguishable by the pleopods being apically not so much broadened as in the latter species. Parapagurus pilosimanus Smith.

Therefore, it had better be placed distinct from it until a larger supply of materials makes possible a thorough revision of these Coenobite forms. Coenobita hilgendorfi, n. nom.

Coll. Mus. On Hilgendorf’s authority (1. c.), we learn that Cancer clypeatus Herbst (1794) is not identical with Latreille’s Canodbita clypeata (1826) but is the same as Caenobita diogenes M.-Edw. (1837). It then follows that the proper designation for the last men- tioned species should be Cenodbita clypeatus (Herbst). Since, now, this C. clypeatus (Herbst) is clearly a species distinct from C. c/ypeata Latr., the latter must receive a new specific name. Consequently I have proposed to call it Cænobita hilgendorfi.

Mus. there are of this species: a male from Oshima, Prov. Idzu, and several specimens from Bonin Islands, Loo-choos, and from Tansui in Formosa. A male specimen exists also in Mr. M. Nakamura’s collection made in the Niigata Prefec- ture but there is ground to assume that the specimen was not captured at that locality, but was brought over from a warmer region. The presence or absence of an oblique file on the outer surface of left chela can not be much relied upon as an important specific character, for I find that in some individuals it is not at all or but so very little developed as to be scarcely distinguishable as such. ‘The outer surface of the propodus and dactytus of the third left leg is sometimes simply rounded; in other cases it shows a longitudinal edge which is generally ill-defined but may sometimes be sharply defined, The coxal elongation of the fifth pair of legs is in no case so elongate as has been figured by authors (f. i., by Alcock, op. cit., pl. xiv, fig. 2a), and that even in those individuals which come close to C. perlatus. Although the material at my disposal does not suffice to form a complete connecting series between C. rugosus and C. perZatus, yet I am greatly inclined to think from a consideration of the above mentioned facts that some day it may become necessary to unite these species into one.

PAGE 393 435 443 459 467 483 489 519 531 Die Cixiinen Japans. Von Prof. S. Matsumura, Rigakuhakusht. Unter meinem Cixiinen Material habe ich 46 Arten gefunden, von welchen 2 Gattungen und 42 Arten neu sind und deren wissenschaft- liche Diagnosen ich hier folgen lassen will. Die aufgefundenen Arten verteilen sich auf 10 Gattungen, namentlich, Macrocixius (n. g.), Cixius, Kuvera, Betacixius (n. g.), Oliarus, Trirhacus, Brixia, Kirbyana, Mundopa und Barma. Die Gattungen Cixius und Oliarus kommen in der ganzen Welt vor, also sind Kosmopoliten. Die fünf Gattungen—Kuvera, Brixia, Kirbyana, Mundopa und Barma—sind bis jetzt nur fiir Ost-Indien nachgewiesen, kommen aber nach meinem Befunde auch in Formosa vor. Weiter ist die Gattung Kuvera sonderbarerweise auch in Nordjapan sehr häufig zu Hause. Während Macrocixius dann und wann in Südjapan und Formosa angetroffen wird, beschränkt sich Befacixius so weit wie bekannt nur auf Mittel- japan, Formosa und Siidchina. Das benutzte Material wurde grôsstenteils vom Verfasser selbst gesammelt. Doch wurde ein Teil desselben ihm zugestellt aus Oki- nawa Insel von Herrn K. Kuroiwa; aus Formosa von Herren T. Shiraki, M. Ishida und I. Nitobe; und aus Mitteljapan von Herren Y. Nawa und S. Iguchi. Allen den genannten Herren spreche ich hiermit meinen herzlichen Dank aus. Macrocixius gen. n. Der Form nach Cirius Latr. sehr ähnlich, unterscheidet sich jedoch wie folgt: 1. Scheitelrand sehr hoch, der in der Mitte des Scheitels sich befindliche Längskiel undeutlich oder sehr niedrig, am Ende mit 304 S. MATSUMURA: einem hohen und fast geraden Querkiele ; am Stirngipfel verläuft auch ein gerader Querkiel und bildet mit dem Scheitelquerkiel eine breite Querfurche. 2. Gesicht schmal, in der Mitte etwas breiter, Stirn ausgehöhlt, der Mittelkiel niedrig, sodass der Clypeus ovalförmig sich etwas erhebt. 3. Rostrum lang, die Mitte des Hinterleibs erreichend, das zweite Glied viel länger als das dritte. 4. Elytren fast wie beim Czazus nervirt, nur an der Spitze mit 2 gegabelten Endnerven; die sämmtlichen Nerven ohne Kérnchen. Der Gabelnerv des Clavus liegt ganz dicht am Rande. Typus: Macrocixius giganteus Mats. Macrocixius giganteus sp. n. (Fig. 1.) Castanienbraun.

On Four Polycystid Gregarines from the Intestine of Tribolium ferrugineum F. By S. Ishii, Rigakushi. With 4 Figures. In the intestine of the beetle, Zribohum ferrugineum F., I have found four polycystid gregarines, of which one is referable to the already known species Gregarina cuneata F. STEIN, while the remain- ing three are forms apparently not yet described. The host beetles were collected in the Province of Izu in the early part of October last year. 1. Gregarina cuneata F.

ISHIT: This form greatly resembles Gregarina polymorpha (HAMMER- SCHMIDT), but differs from it in being generally smaller, in the frequent absence of protomerite in the satellite, and in the spherical shape of cysts. In G. polymorpha, so far as I know, the protomerite is always present and the cyst is of an oval shape. 3. Gregarina crassa sp. nov. (Fig, 3). Fig. 3. Gregarina crassa n. sp. 360x. Sporonts usually in association. Protomerite ovoid, relatively very small, always broader than long, usually not visible in satellite. Deutomerite also ovoid, very large, rounded posteriorly. Satellite with posterior part of deutomerite usually somewhat narrowed. Between the two segments of body there exists a distinct constriction. Epicyte thin, especially so in protomerite. Sarcocyte very thin all over, being not much thicker than epicyte. Septal region not thick, inconspicuous. Endocyte almost clear in protomerite, with only a few number of granules; but very dense in deutomerite, giving it a dark brownish black colour. Nucleus usually situated near the middle of deutomerite. It is only vaguely visible owing to the great denseness of the endocyte.

In one case I have found a free sporont which was apparently without protomerite. It was slightly narrower at one end of the body. Probably I had only a detached satellite before me. Infection not heavy, nor common. This form resembles in some points Gregarina Steint which was described by BERNDT” from the intestine of Zenedrio molitor, but differs from this in the much smaller protomerite, in the thicker deutomerite, and in the frequent absence of protomerite in the satellite. 4. Steinina obconica sp. nov. (Fig. 4). In trophic stages always solitary. Epimerite not deciduous, somewhat conical in shape, small and short, having an average length of only 6y. On several occasions 1) BERNDT, A.— Beitrag zur Kenntniss der im Darme der Larve von Texedrio molitor lebenden Gregarinen.” Arch. f. Protistenk., Bd. 1., 1902. 440 S. ISHII: I have observed the animal attached to the epithelium of host intestine by the small epimerite.” Protomerite half-moon-shaped, more or less compressed antero-posteriorly, always broader than long. Deutomerite rather obconical, broadest close to the septum, narrowing posteriorly and ending with obtuse end; usually 3 or 4 times as long as the protomerite. ‘The constriction between the two segments of body is in most cases not con- spicuous, often nearly so obsolete as to obscure the distinction between protomerite and deutomerite. Epicyte thin, especially so in protomerite. Sarcocyte thin near the septum, but thicker Fig. 4. Steinina obconica n. sp. towards the posterior end of deutomerite; thick- AG fa end also along the anterior end of protomerite. Septum very thin, inconspicuous. Endocyte very dense and dark in both segments, lighter towards the posterior end of deutomerite evidently owing to the thinning of body. Nucleus can not be clearly seen in living specimens, it being deeply imbedded among endocytic granules. It is situated usually in the broadest portion of deutomerite. In many cases the body is bent toward one side, giving rise to a shape remotely resembling that of a comma. Cyst large, spherical or somewhat ovoid.

Length of deutomerite, 112 4, 112, 1164, 807, 100 y. 1) The so called “ bouton aplati” of LÉGER et DuBosco (‘ Nouvelles recherches sur les grégarines et l’épithélium intestinal des Trachéates,’ Arch. f. Protistenk., Bd. 4., 1904.) is likely something different from true epimerite. FOUR POLYCYSTID GREGARINES. 44I Breadth of body, 68, Som 804, 52/4, 561.

This gregarine differs from Steinina ovalis (F.

Unter meinem Material von einheimischen Ascidien, das keineswegs als erschöpfend bezeichnet werden darf, finden sich nicht weniger als acht Arten, die ich hier kurz beschreibe.

Von dieser Art liegen mir 2 Exemplare vor, die beide von dem amerikanischen Dampfer ‘ Albatross” erbeutet wurden. Das eine besitzt einen kegelförmigen, vom Rumpf deutlich abgesetzten Stiel, das andere dagegen ist an der Ventralseite einfach zugespitzt. Beide stimmen mit den Beschreibungen früherer Autoren durchaus überein und geben keine Veranlassung zu weiteren Bemerkungen. Nur die Fundorte liegen bedeutend weiter nach Süden als der bekannte südlichste. Interessant ist auch die Tatsache, dass das Tier, welches in seiner Heimat im arktischen Gebiet nur in geringer Tiefe vorkommt, an dem südlicheren der beiden Fundorte aus einer bedeutend grösseren Tiefe erbeutet wurde. 2.

Fundnotiz : Kamtschatka, 40 und 43 Faden (Coll. “ Albatross ”) ; 2 Exemplare. Anmerkung. Diese Art, die ich dem russischen Ascidiologen Dr. W. Redikorzev widme, gehört eigentlich noch nicht in die japanische Fauna. Ich habe sie trotzdem in diese Notizen aufgenommen, da es 448 DR. ASAJIRO OKA: hôchst wahrscheinlich ist, dass sie, ähnlich wie die vorige Art, sich bis zu den Kurillen verbreitet. Durch die eigentiimliche Lage der getrennten Gonaden erinnert diese Art zunächst an Molgula retortiformis Verrill, aber diese letztere besitzt 7 Falten jederseits am Kiemensack und auffallend lange Siphonen. Auch liegt der linke Hoden nicht nur in der Darm- schlinge, sondern erstreckt sich auch unterhalb derselben. Bei M. siphonalis Sars, die ebenfalls getrennte Gonaden besitzt, ist die Lage des linken Hodens wieder eine andre, indem er gänzlich unterhalb der eng geschlossenen Darmschlinge gelagert ist. Am nächsten scheint mir die neue Art noch der Molgula crystallina zu stehen, mit der sie ausser der Zahl der Kiemenfalten noch eine Reihe äusserer Charaktere gemein hat. 3. Molgula rotunda n. sp.

ASAJIRO OKA: loides Bened. am nächsten zu stehen. Sowohl im äusseren Habitus wie auch in der eigentiimlich gekriimmten Darmschlinge stimmen die beiden Arten vollkommen überein, aber die neue Art hat einen glatt- randigen After statt eines gezähnelten. Auch die Zahl der Längs- gefässe auf den Kiemenfalten ist, wenn auch unbedeutend, bei beiden Arten verschieden. 4. Molgula japonica Hartmeyer. EiigerZ. Fig. 8. Molgula japonica. Von links. x1.

Anmerkung. Das einzige Exemplar stimmt in allen wesentlichen anatomischen Merkmalen mit der Beschreibung von Hartmeyer so genau überein, dass ich nicht anstehe, dasselbe dieser Art zuzurechnen. Wie unten erwahnt wird, findet sich unter japanischen Molguliden eine Art, die in der Lage der linken Gonade innerhalb der Darm- schlinge, zwei andre, die in der eigentiimlichen Beschaffenheit der Muskulatur mit dieser Art übereinstimmen, alle drei sind aber in anderweitigen Charakteren von dieser Art ganz verschieden. Merk- wirdig ist, dass in der Bucht von Tateyama, wo ich seit siebzehn Jahren Ascidien sammle, diese Art bisher nur einmal und in einem einzigen Exemplar gefunden worden ist. 452 DR. ASAJIRO OKA: 5.

Fundnotiz. Japanisches Meer, bei Idsumozaki, Prov. Echigo (Coll, M. Nakamura); 3 Exemplare. Anmerkung. Diese Art unterscheidet sich von allen andern japanischen Molgwla-Arten hauptsächlich durch den eigentümlichen äusseren Habitus, der unwillkürlich an die Schneckengattung Xenophora erinnert, deren Schale ebenfalls mit leeren Molluskenschalen bedeckt ist. Betreffend der inneren Anatomie weist sie keine auffälligen Eigentümlichkeiten auf, liess sich dennoch mit keiner der bekannten Arten identifizieren. Uber eine neue Art von Trichostrongylus aus dem Darme des Menschen in Japan, (Trichostrongylus orientalis n. sp.). Von Dr. med. Kotaro Jimbo, Assistent der medizinischen Klinik der Universitat in Tokyo, (Direktor : Prof. Irisawa). hierzu 107. %. Im Darme der Japaner habe ich mehrfach eine der Nematodengat- tung Zrichostrongylus Looss unverkennbar angehörige Art gefunden, welche, nach einer genaueren Untersuchung, sich als eine mit keinen der bisher bekannten Arten jener Gattung vereinbare Form heraus- stellte.” Herr Professor Ijima, den ich in der Sache zu Rate zog, ist auch der Ansicht, dass es nötig sei, den Parasiten mit einer besonderen Bezeichnung zu belegen, und seinem Vorschlage nach gebe ich ihm den Namen Trichostrongylus orientalis. Schon 1889 hatte Ogata” über einen kleinen Fadenwurm berichtet, den er zu Hunderten im Magen einer verstorbenen Japanerin entdeckte und welche später von Ijima” unter dem Namen Strongylus subtilis Looss 1895 (= Trichostrongylus instabilis Railliet 1893) näher beschrie- ben wurde. Leider ist kein Exemplar des Ogata-Iima'ischen Zrzcho- strongylus in Erhaltung geblieben, sodass ein direkter Vergleich des- selben mit der von mir aufgefundenen Art nicht mehr unternommen werden kann, Jedoch ist Herr Prof. Jima jetzt stark der Ansicht an- geneigt, dass sein S/rongylus subtilis mit meinem 77. orientalis iden- tisch ist; jedenfalls weiss er keinen Grund mehr die Richtigkeit seiner damaligen Identifizierung auch heute zu behaupten. Auch das neulich gewordene Vorkommen von durch Kitamura und Oishi bekannt Strongylus subtilis als menschliche Darmparasiten in Südjapan und 460 KOTARO JIMBO: Korea scheint mir höchst wahrscheinlich sich nicht auf jene Art, son- dern auf 77. orientalis zu bezichen, Was nun das Material, welches der genannten neuen Art zugrunde liegt, anbelangt, so habe ich es hauptsächlich aus 27 (unter 57 darauf untersuchten) Leichen entnommen. Als der Sitz des Parasiten ist stets das Duodenum, in einigen Fällen auch der Magen und der obere Teil des Jejunums, anzuführen, Er wurde meistenfalls in sehr geringer Individuenzahl, zwar unter 10 und nur ausnahmsweise 50 oder noch darüber, angetroffen. Ausser den Leichen habe ich 5 Patienten unter Behandlung gehabt, die mit demselben Parasiten behaftet und die mir von Zeit zu Zeit frisches Material lieferten. Im Ganzen, die aus den erwähnten Wirten erhaltenen Würmer betragen 219, wovon 56 Männ- chen und 163 Weibchen sind. Meines Wissens sind bis jetzt nur vier Arten von Trichostrongylus bekannt gewesen, —also diejenigen vier Arten, welche Looss schon bei der Aufstellung der genannten Gattung zusammengestellt und systema- tisch auseinandergesetzt hat. Es sind nämlich 77. retortaeformis (Zeder 1800), 77. instabilis (Railliet 1893), 77. probolurus (Railliet 1896) und Tr. vitrinus (Looss 1905). In allgemeinem Aussehen sowohl wie in baulicher Hinsicht stimmt nun 77. orintalis mihi wesentlich überein mit 5 auch Tr. instabilis (= Strongylus subtilis Looss), von welchem Looss schon früher eingehende Beschreibung und Abbildungen gegeben hat. Es handelt sich also um dünnen und zarten Fadenwürmern (Taf- V, Fig. 1.) von grauweisslicher Farbe oder fast farblosem Aussehen ; Körperlänge im geschlechtstreifen Zustande 4.8-3.8 mm bei Männchen, und 6.7-4.9mm bei Weibchen; beide Geschlechter am dicksten in der Gegend der Genitalöffnung, von welcher sich der Körper nach vorn allmählich und gleichmässig verjüngt ; Körperbreite beim Männchen direkt vor den Spicula 0,079-0,072 mm, am Kopfende ca. 0,00 7 mm; dieselbe beim Weibchen auf der Höhe der Vulva 0,083-0,075 mm, am Kopfende ca. 0,090 mm. Haut mit Querringelung, doch ohne Längs- kanten, Mundöffnung mit drei knötchenförmigen Papillen versehen, TRICHOSTRONGYLUS ORIENTALIS n. Sp. 461 sonst mit keinerlei charakteristischer Ausstattung. Oesophagus einfach, etwa 0,8 mm lang, mit ebenso beträchtlicher Variation wie die Körper- länge. Gehirn und Excretionsporus ca. 0,1 mm hinter dem Kopfende. Beim Männchen beginnt der Hodenschlauch etwa 0,06 mm hinter dem Oesophagealende ; Bursallappen in ausgebreitetem Zustande (Fig. 2) ca. 0,23 mm breit in transversaler Richtung, jede Lappen ca. 0,13 mm breit an der Basis in dorsoventraler Richtung. Beim Weibchen Vulvar- öffnung in der hinteren Körperhälfte, 1,47-0,84 mm vom Schwanzende entfernt; Uterus enthält 10-20, meist!noch nicht in Furchung gelangte Eier ; vorderes Eirohr erreicht vorn eine etwa 1,0 mm vom Kopfende entfernte Stelle, biegt da zurück, und endet nach einer weiteren kurzen Strecke; das hintere zieht nach hinten bis etwa 0,15 mm Entfernung von der Schwanzspitze heran, kehrt dort um, dann kommt vorn an die Höhe von etwa 1,4mm Entfernung vom vorderen Ende, sodann kehrt wieder um, um schliesslich nach einem hinterwärts gerichteten ca. 0,3 mm langen Verlaufe zu endigen. Von besonderer taxonomischen Wichtigkeit, in Bezug auf die von Looss niedergelegten Diagnosen anderer Mitglieder der Gattung, sind aber die folgende Charaktere: Männchen): Bursallappen jederseits mit zwei weit auseinander- weichenden Ventralrippen ; von diesen die ventroventrale dünn, isoliert ventralwärts gerichtet; die lateroventrale sehr dick, dicht an der Ex- ternolateralrippe gelagert. Letztere fast gleich dick wie die latero- ventrale, und wiederum in fast ganzer Länge direkt an der leicht schlänkeren Mediolateralrippe gelagert. Posterolateralrippe noch etwas dünner und merklich kürzer, fast gerade, jedenfalls gar nicht dorsal- wärts gebogen, sich divergierend von der vorhergehenden Rippe nur in dem distalen Drittel ihrer Länge, mit dem Ende bis kurz vor den Bursalrand heranreichend. Externodorsalrippe kürzer als die letztere Rippe, schwach s-förmig gebogen, die Endpapille etwa halbwegs zwi- schen den Enden der beiden angrenzenden Rippen. Die eigentümliche Biegung der in Rede stehenden Rippe bildet ein auffälliges Merkmal 462 KOTARO JIMBO: der Art. Die unpaare Dorsalrippe am Ende gespaltet, die ganze Länge etwa 0,032mm (einschliesslich 0,o11mm lange Gabeliste).— Die beiden spicula 0,133-0,119 mm lang, nach hinten schlank aus- gezogen, bräunlich gelb; Endhaken winzig, kurz vor der Spitze gelagert, sodass der Endabschnitt des Spiculums von einem unbedeutenden Um- fang ist oder vielmehr fast wie schläg abgeschnitten aussieht ; sonstige Gestalt der Spicula aus Fig. 3 zu ersehen. —Gubernaculum 0,085-0,065 mm lang, grösste Breite etwa 0,018 mm, blassgelblich ; Gestalt in frontaler Ansicht aus Fig. 3 zu ersehen, im Profile länglich spindel- förmig, nur ganz schwach convex und nicht wellig gebogen an der Dorsalseite. Weibchen: Der langlich konische postanale Körperteil 0,086-0,065 mm lang, öfters etwas ventralwärts gebogen (Fig. 4).—Vulvaröffnung stellt eine etwas unregelmässig gebogene Querspalte von ca. 0,022 mm Länge dar. Vagina ca. 0,05mm lang, nach innen ein wenig schief vorwärts gerichtet. Der gemeinsame Abschnitt der Ovejektoren zwi- schen den beiden deutlich hervortretenden, ersten Einschnürungen 0,222-0,194 mm lang; ein kleines 0,036-0,029 mm langes Endstück des- selben direkt vor der genannten Einschnürung bei jedem Ovejektore ausgezeichnet durch dichtere und bulböse Ausbildung des Wandes ; darauf folgt ein bauchiger, ca. 0,061-0,059 mm langer und ca. 0,038mm dicker Abschnitt, welcher nach hinten resp. vorn durch eine zweite augenfällige Einschnürung begrenzt ist und wahrscheinlich der Looss’- schen Abteilung I. entspricht?; danach kommt noch der kleinere, elliptische, ca. 0,04-0,32 mm lange und 0,047 mm dicke Abschnitt (Looss’scher IL) mit ausgeprägt dichtmuskulöser Wandung, und schliesslich der dem Uterus angrenzende, verlängerte und verhältnis- mässig dünnwandige letzte Abschnitt (Looss’scher II.) von ca. 0,108-0,09mm Linge; Grösse der Eier im Uterus: 0,091-0,075 mm lang und 0,047-0,039 breit. Beim Vergleich. der Obenmitgeteilten mit den Angaben-Looss’s über die bis jetzt bekannten Zrichostrongylus-Arten (1. c.), besonders TRICHOSTRONGYLUS ORIENTALIS n. sp. 463 in Bezug auf die Charaktere der Spikulen, des Gubernaculums und Bursalrippen beim Männchen, sowohl wie des postanalen Kôrperteils und des Ovejektors beim Weibchen, wird man leicht zur Uberzeugung kommen, dass der vorliegende 77ichostrongylus eine eigenartig charakte- risierte und leicht unterscheidbare Art darstellt. Es scheint nun, dass diese Art eine der in Japan sehr weit ver- breiteten menschlichen Darmparasiten darstellt, und sie wäre in ihrem Vorkommen gar nicht als eine seltene zu bezeichnen sein. Offenbar war die Kleinheit des Körpers viel daran schuldig, dass der Wurm nicht so häufig unter Beobachtung kam wie es sonst der Fall gewesen wäre. Bei der Stuhluntersuchung der Patienten müssten die Aertzte schon öfters die Eier des Wurmes vor sich gehabt haben, aber es liegt hier die Gedanke nahe, dass sie ohne weiters für die des Ankylostomum duodenale gehalten wurden. Den Fehler dieser voreiligen Bestimmung hätte man vermeiden können, würde man nur genauer die Grösse und Beschaffenheit der Eier verglichen haben. Zur Veranschaulichung des Unterschieds beider Ei-Arten diene Fig. 5, welche von einem die beiden enthaltenden Stuhlpreparat entnommen ist. Klinische Beobachtungen auf den mit dem oben beschriebenen Parasiten behafteten Patienten werden am anderen Orte berichtet. Nur sei hier erwähnt, dass der Parasit, so weit wie meine bisherige Erfahrung reicht, keinen bedeutenden pathologischen Einfluss auf den menschlichen Wirten auszuüben scheint.

In his “List of Holothurians known to occur in Japan”? the late Prof. K. Mitsukuri gave seven species of Synaptids, founded on the reports of v. Marenzeller and Théel. They are: 1) Synapta in- certa, var. variabilis Théel [=Zabidoplax dubia (Semper)]; 2) S. ooplax v. Marenzeller [=Leptosynapta ooplax]; 3) S. distincta v. Marenzeller [=Protankyra bidentata (Woodward et Barrett)]; 4) S. autopista v. Marenzeller [=Protankyra autopista]; 5) S. aculeata Théel [=Protankyra aculeata|; 6) Chiridota japonica v. Marenzeller [= Scoliodota japonica]; and 7) Ch. rufescens Brandt [= Polycheira rufescens |. Since that time four more species have been reported from Japan and adjacent localities, viz., 1) Myriotrochus minutus Ostergren; 2) Anapta ludwigi Britten; 3) A. amurensis Britten; and 4) Chiridota regalis Clark. To the above list of eleven Synaptid species, I have added seven more, besides an indeterminable form, in my report on the Holothurians collected by the “ Albatross” off the coasts of Japan, which report will shortly be published in another place. Further, from examination of the Synaptide in the Science College Museum, I have come to know that there still existed five more species, including one new species, to be added to the list, thus bringing the number of Synaptid species occurring in the waters around Japan, up to twenty-three altogether. I here propose to present brief notes on all these Synaptids, to supplement in a way the late Professor Mitsukuri’s excellent mono- 1) Zoological Magazine, vol.

Marenzeller) and from the “ Challenger ” Station 233 B, off Sanuki, Inland Sea, 8-50 fathoms (Théel). In a former paper I made notice of spicules being of very differ- ent sizes in radii and interadii. I now find in some specimens that that arrangement is not quite distinctly carried out; nevertheless the anchors and anchor-plates are largest in the middle part of interradii and decrease in size towards radii, Anchors range 170-545 u and anchor-plates 140-430 y in length. Large anchors in interradii show on each arm ten or more minute teeth. 6. Protankyra autopista (v. Marenzeller). Synapta autopista v.

THE SYNAPTID OF JAPAN. 473 This species is fairly well distinguishable from the preceding by the following characteristics. Length of anchors 86-1404 nearly always shorter than wide; each arm of anchor with one or two large teeth near end, which very offen assumes bifurcate appearance on their account; handle of anchor fan-shaped, instead of T-shaped ; anchor-plates irregularly quadrangular, 86-125 » long, commonly with a pair of large holes near centre; miliary granules not X-shaped, but are cup-shaped buttons, 30-50 4 in diameter, each perforated by 3-10 holes; in the radii there are found deeply imbedded smooth, oval granules, 20 4 in diameter. The species has before been reported from Miya Bay (v. Maren- zeller) and from Misaki (Britten). Britten’s statement that it is known from Amoy through Ludwig is a mistake, probably based on confound- ing the species with the preceding. 7. Protankyra aculeata (Théel).

In a speci- men of the present species (no. 1800), I have observed a similar phenomenon in that every hook was longitudinally split by the action of acidiferous alcohol. 17.

(Cat. no. 1127). Moroiso, Misaki (Veretillum beach). Several specimens. Mitsu- kuri coll. Aug. 12, 1897. (Cat. no. 1128). The largest specimen is 55 mm. long and 8mm. broaa. Sigmoid hooks measure 63-1204 in length, exceptionally only 47 yu in the anterior region of body. The hooks gather together into the charac- teristic conical “hook-papille,” each of which may contain them numbering up to sixteen. In the anterior region of body a papilla contains only two hooks, or even one only. The wheels are extreme- ly infrequent, though near the base of tentacles they can be found without much difficulty. Clark presented his Scoliodota as being characterized by the pres- ence of ten tentacles and of hook-papillæ, and by the absence of wheels. The discovery of wheels, extremely rare though these be, and the presence of tentacles in the same number have reduced the differ- ences of the present species from Zrochodota to the one point that the former is in possession of hook-papillæ, which are wanting in the latter. Now, in view of the fact that in Zemiogyrus australianus the presence of hook-papille is not regarded as giving to that species a distinct generic status, the tenability of Clark’s genus Scoliodota becomes doubtful. I should not wonder if it would turn out to be inseparable from Zrochodota. 20. Toxodora pacifica Ohshima. Toxodora pacifica Ohshima, Albatross Holothurians (m.s.). The species is based on a series of specimens secured by the “Albatross”? in Suruga Bay (Station 5073). The character of the genus, very meagrely described by the THE SYNAPTIDÆ OF JAPAN. 481 founder, has been obscure untill Clark placed it on a firm basis by revision of the original specimens. The discovery of the present species should serve as a further support for the validity of this singular genus, Subfamily III. MYRIOTROCHINZ. 21. Myriotrochus ."nleii Steenst ap.

In the Science College Museum there is a specimen of Myriotro- chus, which I may refer to the present species though with much hesitation. It hails from 170 Zéro (=ca. 130 fathoms) in Naka-no- Yodomi, Sagami Sea, having been captured by the late Prof. Mitsu- kuri and Aoki (Cat. no. 1855). The specimen lacks the anterior part and measures only 12mm. by 3mm. The wheels are absent on ventrum ; they measure 175-240 4, on an average 214 y, in diameter ; number of spokes 14-19, on an average 14.5; peripheral teeth number 23-30, on an average 25.6. I have come across only two cases of exceptionally small wheels, measuring So a and I50 4 respectively, but such small wheels do not seem to constitute a dis- tinct class by themselves, as they do in M. minutus Ostergren. Ratio of the number of spokes to that of peripheral teeth ranges from 56.7 to 74%: with a mean of 65%. In Kamchatka specimens I have found the ratio to vary from 60 to 100%, with a mean of 79 %. This seems to stand in accord with the result arrived at by Ostergren and Clark, that the number of spokes tends to decrease in specimens from 482 HIROSHI OHSHIMA: THE SYNAPTIDA OF JAPAN. more southern regions. Noteworthy is the fact that such an arctic form occurs in Sagami Sea (lat. 35° N.). 22. Myriotrochus minutus Ostergren.

Note on a New Termitophilous Coleoptera found in Formosa (Ziaelas formosanus). By Sanji Hozawa, Rigakushi. Zoological Institute, Science College, Imperial University of Tokyo. With Plate VI. Among the specimens of termitophilous insects collected by me during my studies on the Termites of Japan and Formosa, I have found a curious beetle which is apparently a very close ally of Ziaelas insolitus Fairmaire, but seems to be distinguishable from this species in some respects, I propose to call it Zzaelas formosanus. The genus Ziaelas was established by Fairmaire” in 1892 as a new Tenebrionid genus, with the single species Z. insolitus. The genus and species were based on specimens obtained by M. A. Sallé at Hué, Annam. Subsequently the species was placed by Wasmann” under his new family, the Rhysopaussidae,” which constitutes a re- markable group of termitophilous Coleoptera. The species is also found included in the lists of the Rhysopaussidae, in the papers of Gestro,® 1) Fairmaire, L.; Ziaelas n. g. insolitusn. sp. Ann. Soc. Entom. France,- LXI, 1892.

Unfortunately Fairmaire’s description of the beetle is very brief and unsatisfactory. Nothing whatever about its ethology is mentioned. On the ground of Wasmann’s studies, it is to be assumed that the species is probably a termitophilous insect. As to the present species, Z. formosanus, three specimens were collected in 1911 by Prof. Watasé and myself at Kuraru, Ako District, Formosa, They were taken from the nest of Odontotermes (Cycloter- mes) formosanus. The nest of this termite is situated about four feet below the surface of the ground and consists of a royal cell and many other cells containing. each a round spongy fungus-bed. From some cells of the latter kind, I have obtained three speci- mens of the beetle in question, together with numerous larvae of the termite. In organization the beetle shows several peculiar points which seemed to be the result of its life in the nest of the termite, as for instance the elongated eyes and degenerated hindwings. The insect was capable of but very sluggish movements. Here I let follow a description of the species. Ziaelas formosanus, n. sp. Colour.—Dorsal surface dark reddish-brown and ventral surface somewhat lighter, as observed on specimens preserved in alcohol. Head.—More or less longer than broad, divided by a constriction before the eyes into an anterior and a posterior part. Anterior part narrower than the posterior, subquadrate, with a short projection in front, the antero-lateral corner forming a large conspicuous tubercle, underneath which the antenna arises. On the forehead between the 1) Wasmann, E.; Termitophilen aus dem Sudan. Results of the swedish Zoological Expedition to Egypt and the White Nile 1901 under the Direction of L.A, Jägerskiöld.

Post- erior part of head also subquadrate, with slightly rounded lateral edges and slightly concave posterior margin (figs. 2, 3). Antenna.—Rather long, longer than head and pronotum combined, submoniliform, 11-jointed ; Ist joint very large, subcylindrical, nearly 1} times as long as broad, narrow at base and broadening distally ; 2nd joint the smallest of all, orbiculate; 3rd and 4th joints similar, about as long as broad; 5th-gth joints increasing slightly and gradually in breadth and assuming a more and more turbinate form in the more distally situated ones; roth joint somewhat narrower than the preceding one; 11th joint equal to the last in breadth, with slightly obliquely truncated tip bearing fine spiny hairs on the surface (fig. 4). Labrum.—Slightly arched, a little broader than long, subquadrate, slightly sinwate in front, obtusely rounded in the antero-lateral corners and straight on the sides. The margin bears short hairs, of which those on antero-lateral corners are on the whole the longest (fig. 5). Eyes.—Distinctly separated from one another, very narrow, not projecting, black in colour, finely punctured as in other parts of the head but not facetted ; so far as can be seen on the upper side of head, each eye presents a trasversely elongate reniform shape, being broadly emarginated in front. Seen on the sides of head it is nar- rower, shows slight backward curvature near inferior end (figs. 2, 3). Mandibles.—Equal, strong, three-sided, a little longer than broad, reddish brown in colour except the acute incurved tip which is black, upper side slightly convex, outer side concave, lower side much more concave. Inner margin of mandible almost straight with a small notch-like concavity in the middle; outer margin much convex, At inner base there exists a subquadrate tooth-like process with finely serrate inner edge (figs. 6, 7). Pronotum.—Much broader than head, nearly so long as broad, with anterior margin almost straight, antero-lateral margins broadly rounded, postero-lateral margins slightly converging posteriorly, and 486 SANJI HOZAWA : posterior margin slightly sinuate. Dorsal surface of pronotum slightly arched, finely punctured, with three pairs of longitudinal ridges, viz., a median pair formed of the longest ridges and two more pairs formed of antero-lateral and postero-lateral ridges on both sides of the median pair (fig. 8). Prosternum.—With a moderately broad median ridge, anterior margin concave, posterior margin also concave but with a short pointed process in the middle (fig. 9). Elytra.—The elytra in situ (fig. 1), about 2} times as long as broad, distinctly broader than pronotum; base gently arcuate and notched in the middle; lateral edges quite or nearly parallel in basal 2 of their length and then gently curving towards each other before they meet at the apex, giving to this part of the elytra an inverted dome-like outline and showing in this part only an obscure constriction- like depression of surface. Costa numbers ten on each side (fig. 11). The ıst costa forming the inner margin of each elytron is long; the 2nd also long, almost reaching to apex of elytron; the 3rd shorter than the 2nd but longer than the 4th, which is the shortest of all; the 5th longer than the 6th but shorter than the 7th, which is nearly as long as the 2nd; the gth shorter than the 8th; the roth long and forming the outer margin of elytron. Each inter-costal area is beset with a row of minute quadrate punctures with rounded corners. Abdomen.— Dorsal integument soft, not so strongly chitinized as the ventral integument, brownish yellow in colour. Ventral surface rather flat, showing five segments, of which the 4th is the shortest (fig. 10). Legs.—Compressed. First and second legs are of about the same length and structure; tibia shorter and narrower than femur, with very fine lateral and three large terminal spines; tarsus short, thick, dimi- nishing in thickness towards the extremity, 5-jointed; the proximal four joints short; the 5th joint nearly as long as the preceding two joints combined, with two incurved claws (figs, 12, 13). Third leg much longer than the first or the second; tibia with two terminal A NEW TERMITOPHILOUS COLEOPTERA. 487 spines ; tarsus 4-jointed; the Ist joint longer than the 2nd or the 3rd, but shorter than the 4th which is equal in length to the 2nd and 3rd combined. The third leg exceeds the end of abdomen when stretched out posteriorly (fig. 14). Sexual organs.—All the three specimens on hand are of the same appearance and structure. They are probably all males, as one of them proved to be on examination after laying out into sections. The internal male organ consists of testes, seminal ducts, seminal vesicles, accessory glands and ejaculatory duct. Of these parts, the seminal vesicles are the most conspicuous, being very voluminous convoluted tubes, occupying the greater part of the interior of abdomen, They are filled with filiform spermatozoa, Measurements.—One of the specimens gave following measurements : ensthaot body ee. 8.0 m.m. itenetheor head’! hr la. at TSI ni Breadthrof head... alts a Ben ae 1.034 + Bengthiof antenna ee eos ceo ee JOUE encthrot labrum) VIREN 0:37 55 Breadthrofi abano ee a CHARME length of pronotum Mete... 1.6 5 Breadthy Of Pronocumniesaaet eine se 6 eae: 1.6 ” Jeonethtolcytia eroe no 5.5 5p Breadth olrelytras PRE ne. a ZUSE As The two other specimens measured respectively 8mm and 7.5 mm in body length. Remarks.—In external characters, the present species agrees close- ly with the figure given by Wasmann (l.c.) of Ziaelas insolitus, but may be distinguished from this by the more fully rounded shape of the hind end of elytra, instead of this part being marked off from the more anterior parts by gentle constriction at sides. The 4th costa of elytron is shorter than any of the rest, but not so prominent as in the genus Azarelius Fairmaire. 488 Explanation of Plate VI. Pronotum. x20. Fig. 1. Dorsal view. “x6: Fig. 2.

Though the material which came under my examination cannot be {said to be extensive, I have thus far heen able to recognize fourteen species as occurring in the region referred to, Of that number, seven seem to be new to science and one to be new to Japan, while the remaining six represent all those species which have hitherto been recorded from that country.

Certain authors have separated from the Hemerobiidz such genera as Osmylus, Dilar, etc., as representing distinct families, but I agree with Banks” in thinking that it would be more natural to keep up this family in the broad sense, dividing it into four subfamilies as follows: 1) The Dilarinæ, characterized by the peculiar ovipositor of the female and the pectinate antennz of the male. 2) The Psycho- psinæ, characterized by the union of subcosta, radius and radial sector. 3) The Osmylinæ, in which the subcosta and radius are united near tip of wing. 4) The Hemerobiinæ, to include all the rest of the family. Of these subfamilies, the Dilarinæ seems to be well differentiated from all the others on account of the male antenna being of a structure somewhat resembling that in the Sialidæ, and of the ovipositor resembling that of the Rhaphidide. The remaining three subfamilies are very nearly allied with one another; especially close seems to be the relation between the Osmylinz and the Hemerobiine, and it may even become necessary in the future to unite these two subfamilies into one. Here I should mention that the fact of the union of the subcosta and radius, taken alone by itself, does not seem to be always sufficiently adequate to serve as distinctive criterion between the Osmylinæ and the Hemerobiinz ; for, in a new Japanese Osmyline form (Sisyra japonica n. sp.) I have found the union of the said veins only imperfectly carried out. Further, it may be pointed out that Sisyrella nikkoana (Navas), a form generally placed under the Heme- robiinæ,” so closely approaches Szsyra in several respects that it may 1) Synopses and Descriptions of Exotic Neuroptera.

Krüger, in his recent work on Osmylid&”, has presented a new classification of the family, dividing this into two divisions and six subfamilies, mainly on the basis of venational characters. From the point of view that in this group of insects the details of wing-venation, such as are utilized by Krüger, are something much subject to in- dividual variation and therefore can not be solely depended upon for the systematic purpose, it seems to me that Banks’ system before mentioned is the more natural and the more acceptable in the present state of our knowledge.

Under this tribe Banks has placed three genera, viz., Lomamyza, Isoscelipteron and Berotha. Genus Berotha Walker. Berotha Walker, Trans, Ent. Soc. Lond., v. N.S., pt. v, p. 186 (1860); Needham, N.Y.S. Mus., Bull. 86, p. 16 (1905); Banks, ditansa Amer Ent. Soc, XXxIx, D. 212 (1913). This genus differs from Zomamyia in the radial sector being not connected with media. Banks separated Zsoscelipteron from Berotha on account of the former having eight, instead of four or five, branches to radial sector ; however, since some species, as fi. Berotha rufa and B. nicobarica described by Navas,” show seven branches, and since moreover the number of the branches is subject to variation among individuals of one and the same species, I will not give Zsoscelipteron more than subgeneric status unless stronger grounds for its generic separation be forthcoming.

Osmylini Banks, Trans. Amer, Ent. Soc., xxxix, p. 211 (1913). Nymphini Banks, l.c. Banks has separated Osmylini and Nymphini as distinct tribes, but I regard this distinction to be too arbitrary for acceptance, inas- much as there exist between them, so far as I can see, no sufficient difference by which it could be held up. The presence or absence of ocelli, utilized by many other authors for their separation, proves to be of no avail, since there exist under Nymphini forms with ocelli as well as those that are without them. It is therefore obvious that the system of these insects as it now stands, is in much confusion, and hence Osmylini is here put foreward provisionally in the sense which covers Nymphini also. Then the tribe may be defined as follows: Ocelli present or absent; in the latter case there exist tubercles instead. Wings with numerous cross-veins besides those of gradate series; all cross-veins beset with hairs; in forewing media and cubitus have each one branch runing parallel to them for a considerable dis- tance in forewing; in hindwing cubital branch not always parallel to cubitus; no recurrent vein at base of forewing. 1) Névroptères nouveaux de l’extrème Orient. Rev. Russ. d’Entom., xi, p. 112, fig. 2 (1911). 500 i WARO NAKAHARA: In his recent work on the Osmylidæ (l.c.), Krüger has created numerous new genera, many of which are without doubt to be ranged under the Tribe Osmylini as defined above. Whatever be the true status of these genera, they may be considered to be of no concern to the Japanese species known at present of the tribe. The latter I refer to the two old genera, Osmylus and Spilosmylus, which may be distinguished from each other in the following way: Cubitus of hindwing with a branch running for most part along with sand; parallel ste it. ara Osmylus. Cubitus of hindwing with a branch, which, instead of running along with it, makes its course obliquely towards inner margin of the wing. ot, RR LA Ra er Spilosmylus. Here a few words about the genital appendage of Osmylus. Needham (l.c.) has described from the alleged male of Parosmylus prominens, a form later referred to Osmylus, a curious appendage depending from the hindmost abdominal segment and tentatively called by him the “sperm conveyor.” He said: “This is boat-shaped in outline, with a pair of minute palps on the bilobed posterior end. It appears to be capable of being swung in and out on a more or less flexible and muscular pedicel, and when swung inwards, its point must be close to the sperm orifice.” This interesting organ is present in several specimens examined by me, but contrary to Needham’s statements, I have found all those individuals to be females, not males. A living specimen of Osmylus hyalinatus with the organ laid eggs in the paper bag in which it was held in captivity. This shows that both Petersen and Banks are right in considering specimens without the organ to be the males. The male genital apparatus of Osmylus is characterized by the presence of a pair of peculiar free sacs. In the male of Spzlosmylus these are wanting, though the female is in possession of the boat- shaped organ before referred to. ON THE OSMYLINZE OF JAPAN. 50I Genus Spilosmylus Kolbe.

Petersen (l.c.) said that Navas’ Zysmus might be included in the old genus Osmylus, on the ground of the inadequateness of the main character upon which the former was founded; but I think that there exist certain other important. characters, which were not noted by Navas in his generic diagnosis but which seem to sufficiently warrant the generic separation of the two. On the other hand, I agree with Banks in considering Zysmus to be only a synonym of S#zlosmylus. Further, I may say that many of Kriiger’s genera placed under his subfamily Spilosmylinæ are very closely allied to Spilosmylus and can scarcely be distinguished from this. It seems to me that at least two of his genera, Thyridosmylus and Ripidosmylus, should be merged into the present genus, which, in my opinion, may be defined as follows : Ocelli present. Basal joint of tarsi much longer than the next following joint. In forewing, basal part of costal area narrow; costal cross-veins mostly simple; media forked towards base. In hindwing, a row of cells present beyond end of cubitus ; the cubitus has a branch bent posteriorly and not runing parallel to it. Synopsis of the species found in Japan: I.

I agree with Banks in regarding Hyposmylus, Parosmylus and ON THE OSMYLINZ OF JAPAN. SII Dictyosmylus to be synonyms of Osmylus. Moreover, I think that Kriiger’s Plethosmylus is also to be made a synonym of it. ©. hyalinatus M’L., for which he made that new genus, is a species which stands very near to the type of Osmylus, O. maculatus F., as was pointed out by MacLachlan. Consequently, the genus should in my opinion be defined as follows : Three ocelli present, placed close together. Legs with entire empodia ; a spur exists on coxa I in female of most species. Wings broad ; media of forewing forked near base; costal cross-veins mostly furcate, sometimes two adjoining veins cross each other or are con- nected by a short cross-vein; cubitus of both wings has a branch running parallel to it for a considerable distance. The structure of coxa J, which had never before been used for the systematic purpose by any entomologist except Needham (l.c.), who utilized it for generic distinction, seems to afford a useful differ- ential character for the distinction of species.

Remark: The Nikko(?), Hikage, and Tokura specimens agree very well with the original description in wing-markings, while the Kamiköchi specimen deviates from it in the much restricted markings of wings. In the specimen just referred to, the inner marginal area is not uniformly greyish fuscous, but is irregularly clouded with that color ; the ill-defined irregular line running to the wing apex is broken up into pieces, though it is not difficult to trace.

Further, a series of specimens from various localities on the main island of Japan is contained in the collection of the Imperial Agricul- tural Experiment Station, Tokyo. They were kindly shown me by Dr. T. Miyake. Remark: So far as the wing-markings go, this species is very near to O. decoratus. The prothorax in the Kamiköchi specimens shows a coloration variegated with deep black, on which account I have at first doubted if those specimens did not represent a species distinct from O. kyalinatus. P.S. While this paper was under press, I have received Mr. Okamoto’s paper “Zwei neue Arten der japanischen Osmyliden,” Ent. Mitt, Band iii, Nr. 1, Jan. ’14. To my regret, I can not accept the two species described by him as new under the names of Osmylus (Lysmus) japonicus and O. (L.) nipponensis. In my view they are identical with Spzlosmylus tuberculatus (Walker) and S. nikkoénsis (Navas) respectively. On a new Epicaridan Isopod (Athelges takanoshimensis sp. nov.) from Eupagurus samuelis Stimp. By S. Ishii, Rigakushi. With Plate VI. During last summer, while staying at Takanoshima, an islet near the entrance to the gulf of Tokyo, my attention was called to an Epicaridan Isopod belonging to the genus Athelges and found parasi- tic on hermit-crabs which were kindly determined for me by Mr. Terao to be Zupagurus samuelis Stimps. On study, the Athelges turned out to represent a species which seems to be new to science. I propose to call it A. zakanoshimensis. As in other Epicarids, the species shows marked sexual dimor- phism. The male is, as compared with the female, of a very diminutive size besides being of a very different appearance, and is usually found clinging to the metasome of the female in the manner of a parasite, 1. Adult female. The female is found attached, by means of its prehensile legs, to the anterior part of the dorsal surface of the metasome of the host, It stands in contact with the host surface by the entire extent of its dorsal mesosome surface. Consequently, all the prehensile legs are more or less twisted and dorsally directed. The marked concaveness of the dorsal surface is due to the above mode of attachment. All the females were invariably found with the head directed backwards in relation to the host body. 520 S. ISHII, Measurements taken from 3 female specimens are as follows: Body without tail. Spec.

In specimen C, it is 0,8 mm. long and about as wide. It is deeply sunk into the mesosome, and can be seen only from the dorsal side after detachment from the host. Eyes are present in a pair in the anterior part of the cephalon. They are feebly developed and usually not clearly visible from the outside, being more or less concealed under adjacent legs. There are two pairs of rudimentary antenna. Measure- ments of them taken from specimen C are as follows: First or inner antennz (3-jointed) : Basal joint, 0,140 mm. long, 0,140 mm, thick.

ON A NEW EPICARIDAN ISOPOD. 521 Each joint is provided with a greater or less number of short stiff hairs, which decrease in length from distal towards proximal joints. The surface of proximal joints is beset with numerous minute spinous. processes. The mouth is guarded by a pair of mandibles, which are provided in the distal parts with minute curved hooks. These hooks are found on both inner and outer sides of the mouth opening (PI. VII, Fig. 3). The maxillipeds are lamellar. Each is composed of two segments, of which the anterior is larger than the posterior. The anterior segment is anteriorly usually rounded, but sometimes narrowed and obtusely pointed ; without hairs; posterior outer margin concave, with two powerful muscles attached close to it; two short beak-like projec- tions may be seen at the outer border. Anterior end of the posterior segment is elongate and acutely pointed, overwrapping the anterior segment at base. No epignath was observed. Mesosome. Mesosome segments are best defined along the median line of the dorsal surface. The first segment is very narrow and band-like, flanking the cephaion on sides, Length of each mesosome segment in specimen C, as follows. Ist or foremost segment, 0,1 mm. 2nd segment, 0,3 mm. 3rd È 0,5 mm. 4th SE 0,6 mm. sth ss 0,8 mm. 6th 7 0,8 mm. 7th or hindmost segment, 0,8 mm. Sars seems to consider the assymmetry of body in adultfe male Athelges to constitute one of the characteristic features of the genus. At a place he remarks: “ The peculiar contortion of the body in fully grown female specimens has not yet been sufficiently recognized, for the species have generally been described as perfectly symmetrical or nearly so, an appearance which is only exhibited by immature $22 S. ISHII: specimens.” » In the specimens before me, the greater parts of the mesosome does not exhibit contortion to any marked degree, though in the hindmost parts a slight twisting, corresponding to that of the metasome, may often be noticed. Thoracic legs. There are seven pairs of thoracic legs, arranged along sides of the body on the dorsal aspect. They are all prehensile in function and similar in structure. Legs of the first pair are the smallest, those of the second not so large as any other of the more posterior pairs. Each leg is composed of apparently five joints,” not including the coxal piece; of the joints the two proximal ones are the longest, the third and fourth of a medium size, and the fifth the smallest. The fourth is of a somewhat ovoid outline ; a set of two power- ful muscles is seen arising from one end and converging towards the base of the fifth joint, which is of a beak-like appearance and together with the fourth forms a chelate arrangement. The cuticula of the fourth joint is, in the parts which come in contact with the beak-like fifth joint in the depressed state, is considerably thickened, and more- over presents a more or less roughened surface, The distal end of the third joint is provided with a number of minute obtusely pointed cuticular processes (Pl. VII Fig. 5, c.p.). The third and fourth joints seem to be firmly jointed together. No conspicuous muscle seems to occur in the third joint. Measurements of the right leg of the sixth pair from specimen C, as follows: 1) G. O. Sars,—“ An account of the crustacea of Norway,” vol. 2, Isopoda, p. 210, 1899. 2) According to the figures given by G. O. Sars (doc. cit.), it seems that the legs in Athelges paguri (Rathke) are six-jointed. Sars also represents six-jointed legs for other Epicaridan parasites. The third and fourth joints as represented in the figures of Sars together seem to correspond to the single third joint of my specimens. There exists a constriction near the middle of this joint; it is less marked in the male than in the female (Pl. VII Fig. 5). It probably indicates the origin of the joint by fusion of two originally separate segments. The third joint is possibly a combination of carpus and meros, while the first joint corresponds to the basos of an ordinary Isopod leg. ON A NEW EPICARIDAN ISOPOD. 523 Length. Width.

Marsupial plates. Of marsupial plates there are five pairs, Those of the first or foremost pair are of a somewhat complicated structure and differ considerably in shape from all the other, each plate of that pair being made up of two parts, the anterior and the posterior, divided from each other by a distinct constriction (Pl. VII Fig. 6). The anterior part is much the larger, it is folded so as to present a small dorsal and a large ventral lobe. It is by the post- erior inner margin of the former that the plate is attached to the body. The posterior part of the plate is relatively small and narrow, its posterior inner margin is provided with a series of a few (five or six) short hair-like processes. The folded edge of the anterior part is exposed to the outside, projecting far beyond the anterior end of the animal, while all the remaining parts are hidden under the following pairs of marsupial plates. Plates of the second pair are simple, each presenting a more or less cup-like form; the anterior margin is concave, while both the inner and posterior margins are slightly convex. The posterior margin as well as a part of the inner and outer margin are provided with a series of short hair-like processes. The plate is attached to the body by a part of its outer border, and is completely covered over by the next pair, so that it is not at all visible on the outside, The third, fourth and fifth pairs are generally similar to the second in shape. However, in all these pairs the anterior margin of the plates is not concave as in the second; on the contrary, it is slightly convex. The hair-like processes on the posterior margin of the fifth pair are considerably longer than those of other pairs. The marsupial plates gradually increase in size with every pair posteriorly, 524 S. ISHIT: the foremost being the smallest and the hindmost the largest. The convexity of the plates also increases gradually in the more posteriorly situated ones, the fifth pair being in part so vaulted as to present an almost pouch-like appearance. Metasome. The body is abruptly narrowed at the somewhat cylindrical metasome, which thus stands in conspicuous contrast with the massive mesosome. At base rather thick, it gradually tapers distally, finally to terminate with a clavate end-piece. The metasome is usually slightly bent towards the left side of body. It is fairly distinctly segmented, showing six segments inclusive of the clavate end-piece.» Appendages of the metasome or the pleopods are present in only four pairs, the two hindmost segments being devoid of any appendage. The pleopod is attached to the posterior part of the segment it belongs to, and is composed of two ovate or subcircular plates, each with a short stalk and both connected by a short common stalk to the metasome. The size of pleopod is usually larger in anterior than in posterior pairs. All the pleopods seem to be of respiratory nature. Measurements of the metasome taken from specimen A are as follows: Length of entire metasome, 3,5 mm. Thickness at base, 0,8 mm. Length of the two distal segments without appendages taken together, 1,31 mm. Pleopod of the Ist pair, Length including stalk. Width. One of the plates 1,037 mm. 0,651 mm.

Sometimes, but not always, two or four knob-like tubercles are observed near tip of the distalmost segment, which tubercles were considered by Sars to be the rudiments of uropods.” 2. Adult male. The adult male has thick body of an oblong outline, usually somewhat convex dorsally and concave ventrally. It is of a whitish colour, Measurements of a male taken from the female specimen B, as follows: Length of cepalon, 0,255 mm. Length of mesosome, 1,474 mm. Length of metasome, 0,692 mm. Greatest width of body, 0,855 mm. The cephalon is somewhat halfmoon-shaped. There exists on the dorsal surface a pair of distinct but irregularly outlined eyes, widely apart from each other and situated near the posterior margin of cephalon. In one specimen I have observed a pair of small and shallow depres- sions situated near the middle of the dorsal surface of cephalon; each of them presented a somewhat reniform shape measuring 724 in length and lying obliquely so as to be nearly parallel with the side of cephalon. The antennz are short and usually hidden under the cephalon, except the tips of the second pair. The very short first antenne are composed of three joints. The second are slightly longer, and consist I) Joc. cit. p. 200. 526 S. ISHII: usually of seven joints, of which the distal three are very minute and bead-like. In the male taken from the female specimen B, I have observed that the right second antenna was made up of eight joints of which four were bead-like, while the left side one exhibited only seven joints as usual, a fact which stands in accord with what Thielemann® has stated for Isopods generally to the effect that even in one and the same individual the antenna of both sides are mostly somewhat, often strongly, assymmetrically developed. Lengths of right side antenna of the male just referred to are: first antenna 0,118 mm. and second antenna 0,272 mm. (both exclusive of hairs). The basal joint of second antenna is without hairs, the second shows one or two short hairs near its antero-distal end; other joints of that antenna, as also all the joints of the first, are provided with a variable number of short hairs at their disal end. The mouth parts project under the base of antenna as a prominent conical process, at the tip of which the styliform ends of mandibles may be seen. The free end of the mandible seems to become corni- fied, and is of a brownish colour. It is pointed and very slender, having a thickness of only 34 near tip. The mesosome is distinctly segmented, the segments being separated from one another by deep incisions in the lateral parts. There are seven segments in all. ‘These are of much the same appearance, except in the fact that those nearer to both the cephalon and the metasome are somewhat smaller than those in the middle. Measurements of mesosome segments in the male taken from the female specimen B are as follows: Length. Width.

As in these it is composed of five joints exclusive of the coxal piece, of which the first, the second and the fourth are larger than the third and the fifth. The fourth is of , an oval outline and forms a chela with the claw-like fifth joint. The fourth joint shows at the proximal end a few (some seven or eight) short tooth-like processes varying from 4 to 8% in length. The third joint has a few minute spinous processes near the distal end and a single similar process near the middle. Measurements of the fourth left leg of the male taken from the female specimen B are as follows : Length of the Ist or proximal joint, 0,220 mm. Length of the 2nd joint, 0,160 mm. Length of the 3rd joint, 0,076 mm. Length (longest diameter) of the 4th joint, 0,196 mm. Length of the exposed claw of the fifth joint, 0,060 mm. The metasome is small and not divided, all the segments com- posing it being completely coalesced into a single plate-like urus. It is of a triangular shape, attached with base to the mesosome. The posterior end is obtusely pointed, and here the small anal opening is situated. No appendages exist on the metasome. Along each side on the ventral surface there stand at intervals three or four short hairs ; besides, near the posterior end, there is a group of similar hairs, Also on the dorsal surface hairs are present in similar arrangement ; only a posterior group of them is wanting. (The cephalon and the mesosome are also sparsely covered with hairs of the same kind.) The eggs are generally spherical in shape, though often modified into polygonal as the result of mutual pressure in the brood chamber. They measure on an average 0,168 mm. in diameter. They occur in the brood chamber in a very large number. 528 SETISENO 3. Larva. In the brood chamber of an adult female I have discovered a number of larve in the Microniscus-stage. Measurements of an average sized larva: Total length of body, 0,280 mm. Length of cephalon, 0,068 mm. Breadth of cephalon, 0,160 mm. Length of mesosome, 0,128 mm. Breadth of mesosome, 0,156 mm. Length of metasome, 0,084 mm. The cephalon is halfmoon-shaped. It exhibits on the dorsal surface a number of variously sized brownish-black spots, arranged in an irregular group near the posterior margin (Pl. VII Fig. 10). Similar but smaller spots are also present on the mesosome. I could not however find distinct eyes such as were figured by Sars” for the embryo of Phryxus abdominalis (Kroyer) and for Microniscus. The first antenna is short and is usually antero-laterally directed. It consists of three joints and has a length of 0,024mm. excepting the hairs. The second antenna is longer than the first, having a length of 0,280 mm. ; it is usually posteriorly directed. It is provided with a long distal flagellum and six short proximal joints, of which the two distalmost are more slender than the rest. At base of flagellum, there often exists a bristle of some length beset with a few minute spinous processes on one side, In many specimens the fourth joint also shows a long bristle at the distal end. The mouth is situated on a small elevation between bases of antenne. It is guarded by two pairs of appendages yet weakly developed. The mesosome is distinctly segmented, being composed of seven similar segments, There are six pairs of legs. Each leg is composed of five joints excepting coxal piece and is of a similar structure and 1) Zoc. cit. Pl. 9x and 92. ON A NEW EPICARIDAN ISOPOD. 529 appearance as that of the adult, except in being generally somewhat more slender. The fourth joint is ovoid in shape; the fifth is claw- like and comparatively very thin and long. Legs of the posteriormost one or two pairs are usually slightly smaller in size than more ante- riorly situated ones. Measurements taken from the first left leg of a larva are as follows: Length of Ist or proximal joint, 0,040 mm. Length of 2nd joint, 0,026 mm. Length of 3rd joint, 0,012 mm. Length of 4th joint, 0,034 mm. Length of exposed claw, 0,024 mm. The metasome is somewhat smaller than the mesosome. Its posterior end is broadly rounded, excepting the presence of a short median process. It consists of six segments, but is not so distinctly segmented as in the mesosome. There exist five pairs of well de- veloped pleopods, each of which bifurcates into a ventral and a dorsal ramus, the former usually having a single long bristle and the latter two or more of same. The dorsal ramus is articulated to the basal joint, while the ventral one represents only an off-shoot of the latter. The bristles of pleopods are about 76, long. The uropod is large and powerful, with two equally long branches, each measuring 0,104 mm. in length. Tokyo, Oct. 25, 1912. 530 Explanation of Plate VII. Reference letters. Z.a. First antenna. 7z./.

NOTES ON JAPANESE PROTOZOA with Figures and Descriptions of New and Rare Species.” Ry C. H. Edmondson and R. H. Kingman. With Plate VIII. The fresh-waters of Japan afford a wonderful opportunity for the enthusiastic microscopist. Conditions under which simple organisms. thrive are not wanting anywhere in that country. Flooded rice fields of the lowlands, cool mountain streams and innumerable lakes, large and small, are teeming with low plant and animal forms. To what extent systematic study of the microscopic fauna and flora of the waters of Japan has progressed, under the direction of the eminent biologists of that county, the writers of this article are not able to state. With a view of determining the species of Protozoa characteristic of Japan and comparing them with the American forms, microscopic studies were carried on by C. H. Edmondson during July and August, 1912, in various parts of the main island. Beginning with Kobe, observations were made through the central and eastern sections of the country and as far north as Lake Chuzenji. Material was gathered from rice fields, small pools, streams and lakes. Collections were made from the following large lakes: Lake Biwa, altitude above sea level 328 ft.; Lake Hakone, altitude 2,378 ft,; Lake Chuzenji, altitude 4,375 ft.

KINGMAN, territory with considerable variation in local conditions as well as in altitude, the list of species embodied in this brief report may we represent the characteristic unicellular fauna of the entire country. The portion of the article concerned with Rhizopoda is largely a result of the work of R. H. Kingman, a student of zoology, who identified and studied many forms from preserved material. By comparing the list which follows with numerous local records of observers in America and other parts of the world one sees some added evidence of the wide distribution of many species of Protozoa. The accompanying figures, prepared by Mr. Kingman from per- manent mounts, represent new, or rare species of Rhizopods or forms showing considerable variation. Phylum PROTOZOA: Subphylum SARCODINA : Class RHIZOPODA Subclass AMOEBEA. Order GYMNAMOEBIDA. Family Amoebide. Amaba Ehrenberg. A. proteus Leidy; A. guttula Duj.; A. sphae- ronucleus Greef; A. striata Penard; A. radiosa Ehr.; A. saphrina Penard. The species of this genus were not common in any locality.

Of the above species A. vulgaris is the more widely distributed NOTES ON JAPANESE PROTOZOA. 533 in Japan. Lake Chuzenji and the region of Kyoto furnished the best material. Centropyxis Stein. C. aculeata Stein. Found in all localities, Very abundant in Lake Hakone. Great variation in size occurs in this species and some very large forms were observed. Pixidicula Ehrenberg. P. cymbalum Penard. A species rarely observed. Found in material from Lake Hakone. Lecquereusia Schlumberger. L. spiralis Ehr. (figs. 1-3); L. modesta Rhumbler (fig. 4). These two species are widely distributed in Japan, the former being much more abundant. In the typical Z. spiralis the aperture is usualy directed obliquely toward one side with a prominent hump at the outer base of the neck. In the common form in Japan the aperture is directed almost straight forward, in very rare cases there being a slight prominence at the base of the neck. Common in Lake Hakone. Typical examples of Z. modesta were found in lakes on Mt. Rokkozan. L. epistomium Penard, a common species of the high lakes of Colorado, was not observed in Japan. Diflugia Leclerc. D. pyriformis Perty; D. lobostoma Leidy ; D. constricta Leidy ; D. acuminata Ehr.; D. tuberculata Wallich; 2. lebes Penard; D. bacillariarum Perty (fig. 5); D. elegans Penard (fig. 6). Of the species of Diflugia in Japan, D. elegans is apparently the most common. It is widely distributed and shows a great range of variation. D. lebes, not uncommon in some of the lakes of Colorado, was observed but once, in material from the bottom of Lake Hakone. Pontigulasia Rhumbler. P. spectabilis Penard. But one individual observed. From Lake Hakone. A very typical form. 534 C. H. EDMONDSON AND R. H. KINGMAN. Quadrulella Cockerell. Q. symmetrica Schultze; Q. symmetrica var. curvata Wailes (fig. 7). Very typical forms of the species were taken from shallow lakes on Mt. Rokkozan. The variety, observed but once, was found in Lake Hakone. Nebela Leidy. N. collaris Leidy; N. crenulala Penardj N. hippo- crepis Leidy (figs. 8, 9); N. triangulata Lang (figs. 10-14). In the material collected in Japan species of Mebela were very rare. There can be no reason to believe, however, that the genus is not well represented in that country. One individual of the rare species, N. hippocrepis, was found in material from Mt. Rokkozan. In the ooze from the rocks along the shore of Lake Hakone and from the border of a shallow lake on Mt. Rokkozan was found a species which is here listed under the name N. ¢riangulata Lang. The Japan species resembles, in some particulars, Vebela bipes Carter, as described in Clare Island Survey, Part 65, by Wailes and Penard, and may represent an intermediate form between JV, triangulata and N. bipes. In the Japan form the shell is very transparent, compresed, irregular in outline with the fundus region inflated in an asymmet- rical manner. The aperture is slightly oval. Great variation exists in the form of the shell and in the arrange- ment of the plates. In some the plates are circular. or oval, distinctly separated from each other with the ground substance of the shell intervening. In others the plates are closely crowded together and very irregular in outline, while in some the plates are regular in outline but distinctly overlap each other. To The irregular inflation of the fundus is a characteristic feature. Usually the posterior lateral borders are expanded into lobes of variable size. In some these prolongations are pointed as in N. bipes, but more often they are blunt or rounded. Occasionally the NOTES ON JAPANESE PROTOZOA. 535 fundus is truncated posteriorly, sometimes it is strongly concave. The extensions of the fundus are seldom uniform on the two sides of the shell and are never the same in two individuals Usually the narrow view of the shell presents an irregular outline. The com- pression of the shell is seldom uniform, but is always stronger at the fundus border, The size of the Japanese form ranges from 80 to 1004 in length, including the prolongations of the fundus; from 60 to 80m in breadth of fundus and from 28 to 60% in the long diameter of the aperture. No living individuals were observed. i Heleopera Leidy. H. picta Leidy. Material from Mt. Rokkozan furnished the only species of the genus observed. Under high power the plates are seen to be circular, slightly overlapping. Little foreign material is attached to the shell. i | Phryganella Penard. P. hemisphaerica Penard. Frequently observed in many localities. Campascus Leidy. C. dentatus, sp. nov. (figs. 15-18). In 1877 Leidy discovered Campascus cornutus in China Lake, Wyoming, at an altitude of 10,000 feet. Apparently the species has not been observed since that time. More recently Penard described two species of the genus, Cam- pascus triqueter and Campascus minutus, from the deep lakes of Switzerland. In both species described by Penard the fundus is without the horn-like prolongations of the form observed by Leidy. Campascus minutus was reported by Wailes in 1912 from the New York water-supply drawn from Croton Lake Reservoir. The form under consideration, which is apparently a new species, was found in the ooze taken from the rocks along the shore of Lake Hakone, Japan, in August, 1912. The description follows: Shell of yellowish, chitinoid material similar in general outline to Campascus cornutus. Under high power 536 C. H. EDMONDSON AND R. H. KINGMAN. the shell has the appearance of being distinctly punctate. In some individuals the punctae are arranged in a regular diagonal manner, in others there is no regularity about the arrangement. In no specimens examined can outlines of plates be detected even with the oil immersion lens, The neck is short and sharply bent, nearly at right angles to the long axis of the shell. The circular aperture is bordered by a thin delicate membrane of approximately 44 in breadth. A number of short, blunt, tooth-like prolongations are present on the posterior border of the fundus. From three to seven of these processes are usually present. They vary in size and when numerous give an irregular, crenulated appearance to the posterior edge of the fundus, when the broad side of the shell is viewed. In Leidy’s species the two horns are directed laterally and pos- teriorly, their tips not projecting beyond the posterior border, giving the fundus a rounded outline when the narrow side of the shell is observed. In this species the teeth-like points are directed backward and project beyond the border, giving the fundus the appearance of terminating in a spine when the narrow side of the shell is seen. Leidy records the size of Campascus cornutus as ranging from 0.112 mm. to 0.14 mm. long by 0.18 mm. broad. This species of Japan is much smaller. The length of the shell, including the spines and the collar about the aperture, ranges from 60 to 804. Breadth of fundus from 50 to 66y. Greatest thickness, narrow view, 284. Aperture 124 in diameter. The living organism was not observed. Paulinella Lauterborn. P. chromatophora Lauterborn (fig. 19). Empty shells of this very minute form were found in material from the bottom of Lake Hakone and also from shallow lakes on Mt. Rokkozan. The shell is composed of five longitudinal rows of plates and possesses a short neck. The Japan form is very typical. NOTES ON JAPANESE PROTOZOA, 537 Cyphoderia Schlumberger.

One of the foremost objects of my recent visit to Japan and other places in the Pacific was to study the development of as many different species of Echinoderms as possible with the view of making a comparative study of the larval forms, in order to see if there is any real interrelation between the shape and structure of the larve and the natural relationship of the grown-up forms of Echinoderms. Should it prove to be a rule that within an order or family the larve all possess certain characters in common, one may be justified in drawing conclusions from the characters of the larva as to the rela- tionship of the mature forms, and thus obtain certainty in cases where doubt reigns as to the natural position of these. This is exactly the case with some common Japanese Echini. I may recall the fact that I have in my “Ingolf” Echinoidea (I) made a complete rearrangement of several groups ot Echini, both families and genera, e.g. the genera Echinus and Strongylocentrotus, to which were previously referred a great number of species, which, according to my views, ought to be referred not only to different genera but even to different families. I thus maintained that the species Strongylocentrotus tuberculatus and depressus are no true Strongy- locentrotus, but that the former belongs to the genus Zoxocidaris of the family Echinometride, and the latter to a separate genus, Pseudocentrotus, 544 TH. MORTENSEN: DEVELOPMENT OF of the family Zoropneustide. On the other hand, I maintained that another common Japanese sea-urchin, Spherechinus pulcherrimus, is no Spherechinus at all, but a true Strongylocentrotus—As regards the position of the genus S/rongylocentrotus, I was somewhat in doubt, thinking it most probably to form a subfamily of the Toropneustide. These conclusions, arrived at mainly from a comparative study of the pedicellariæ of these forms; have not met with a complete approval. While they were in the main accepted by Déderlein, another authority on recent Echinoids, H. L. Clark, is for the main part strongly opposed to them.—I shall, of course, not enter into details here, the more so, since I have at present no access at all to the necessary literature.—I was then naturally very anxious to study the development of these three forms, in order to see if any deductions could be made from the shape and structure of their larva. While I have got the complete development of Toxocidaris tuberculatus and nearly so of Strongylocentrotus pulcherrimus, I could not obtain the development of Pseudocentrotus depressus, because its sexual products were not ripe yet at the time I had to leave Japan. But the first two, I am very satisfied to say, proved to be in ac- cordance with my views. Strongylocentrotus pulcherrimus.—The larva of this species is in its younger stages very much alike to that of Strong. droebachiensis. The body skeleton consists of a long club-shaped rod, the posterior end of the body being thus elongated, as is the case in the larva of Strong. droebachiensis and of true Æchinus species. This fact induces me to think that, in reality, Strongylocentrotus is nearly related to the Achinide s. str. and not to the Zoropneustide, in which latter family the larvae have quite another shape, viz. a short body with a complicated body-skeleton forming a peculiar frame. So it is at all events in Spherechinus granularis and—as I have been able to as- certain here in Japan--also in Zoxopueustes pileolus. I should be very much surprised if the same does not prove to hold good for Pseudocen- SOME JAPANESE ECHINODERMS. 545 trotus depressus; but this point must be left to one of my Japanese colleagues to ascertain. In the later stages of Strong. pulcherrimus-larvæ, the long body rods are resorbed and the body shortened, just as in Zchinus larva. (It is with purpose that I do not say ‘as in Strong. droebachiensis larve. It is true Agassiz has described the complete development of this species, but, as I have already shown in my first paper on Echinoderm-larvæ [,,Die Echinodermenlarven d. Plankton-Expedi- tion ”], he has there confounded other larve with those of that species). In the latest stages reached, the larve had just begun to show signs of approaching metamorphosis; but vibratile epaulettes had not yet formed. If they form at all in this species is a question I am sorry I must leave undecided. (In the larva of Strong. droebachiensis there are epaulettes; I can say this, having obtained some larve in Planktor samples from Greenland, where no other Echinoid occurs, making the correctness of the identification of those larve beyond the reach of doubt). The rods of the processes are all simple, not fenestrated. Toxocidaris tuberculatus—The larva of this species is quite different in body shape and in the structure of skeleton from that of Str. pulcherrimus. In the first stage it is similar to that of Zoxo- pneustes pileolus : the body is short, and the skeleton of the body forms a frame, the rods being very strongly thorny. In a later stage, a posterior cross- rod is developed, ending in two very peculiar postero- Fig. 1.—Posterior cross-rod and postero-lateral rods of lateral rods, which ER 300 the larva of Toxocidaris Zubercwlatus. —— are stronglythorny 546 TH. MORTENSEN: DEVELOPMENT OF and look somewhat like the antlers of a stag (Fig. 1). The rods of the postoral and the postero-dorsal processes are fenestrated. There are four vibratile lobes, but no epaulettes. It is evident that this larva does not suggest any relationship with that of Strong. pulcherrimus. On the other hand, my conclu- sion that Zoxocidaris belongs to the Zchinometride gets, for the present, no support from the structure of the larva. No Echinometrid- larva is known with certainly as yet. I have described in the » Festschrift für Spengel” a very curious larva from the West Indies, with a pair of extremely long lateral processes, which larva I think must be referred to Echinometra lucunter. It is certainly very different from that of Zorocidaris tuberculatus. But so long as we know so very little of larva within the family Achinometride, it is of course impossible to draw any conclusion from the shape of its larva against the position of Zorociaaris within that family. Temnopleuride.—Hitherto there was not known any Temnopleurid- larva. I was therefore very satisfied in getting the opportunity of rearing the larva of three different Temnopleurids, viz. Zemnopleurus toreumaticus, Pleurechinus sp. and Mespilia globulus. They all agree in the structure of body skeleton: the main rod has a median process off the posterior end of the stomach, and beyond this process there is a short prolongation, which becomes absorbed in the later stages. The postoral and postero-dorsal rods are fenestrated. These larva tend to show that there is a special type of larva within the family of Zemnopleuride, characterized mainly by its body skeleton. As might be expected, they differ from one another in several minor points; but I cannot enter here on these details. The larva of Mespilia is one of the most beautiful larvae of Echino- derms known to me. The four main processes are very wide, with epaulettes across their base; there is a posterior cross-rod, ending in small branching postero-lateral rods. Of the two other forms I have SOME JAPANESE ECHINODERMS. 547 not got the larve sufficiently advanced in development to ascertain whether or not they have a posterior cross-rod and postero-lateral processes, Of the Spatangoidea I have succeeded in getting ripe material of only one species, Brissus Agassizi. Owing to the lateness of the season when I got that material, the larvae did not reach their final shape before I had to leave Japan. The postero-lateral rods, in which the specific characters of Spatangoid-larve are mainly found, have not yet developed, so that the main character of this larva cannot be given. The larva is, otherwise, of the form typical to Spatangoids. The posterior process is rather short; the rods of this process as well as those of postoral and postero-dorsal processes are fenestrated in their whole length. The Clypeastrotdea yielded considerably better results. The larva of four species were reared, viz. Clypeaster japonicus, Mellita japonica,” Laganum decagonale and Laganum fudsiyama. It may first be pointed out that these larve all agree with those of other Clypeastroids hitherto known in their skeletal structure and general shape. There is no necessity for giving here further details as regards the larva of Clypeaster and Mellita. It may be enough to say that in the C/ypeaster-larva the body skeleton is quite smooth, with some branches at the lower end of the frame, while the Mellita-larva is very similar to that of the Mellita from the Atlantic coast of North America. Laganum fudsiyama” affords special interest in that it is a deep-water species; I have got it from depths of 200-809 meters. This is the first time that an Echino- derm from the deeper water was studied as regards its development. 1) This species is designated in Yos/iwara’s Monograph of the Japanese Echinoidea as Astriciypeus Manni. Having no access to literature at present, I do not venture to say that this is an error; but anyhow I do not see why this should not be a Mellita, and if I remember correctly, there is a Melita japonica. 2) Possibly this is really Laganum pellucidum; but I have not been able to decide the point for want of literature. 548 TH. MORTENSEN: DEVELOPMENT OF It is interesting to note that it has quite typically pelagic larve of the common Clypeastroid shape. As it was only during the last days of my stay in Misaki that I got the ripe material of this species, I naturally have succeeded only in getting the first stages of the larva, I should take the occasion here to mention that, while in general I think that deep-sea Echinoderms have no pelagic larve but undergo more or less direct development, there exist—perhaps only among the archibenthal forms, and not among those from very deep waters— some that have pelagic larva. Thus, I venture to maintain from the small size of the eggs, that a small species of Ovechinus (?) which I have got from the Sagami Sea, will, like the Laganum men- tioned above, prove to have pelagic larve. The same I should think will hold good also for Salenia pacifica, Hemipedina a.o. Unfortunately I could not get sufficient material of these forms for studying their development. Laganum decagonale proved to be especially interesting as re- gards its development. The eggs are comparatively large, measuring nearly 0,5 mm. in diameter, and are yolky, in accordance with which fact the development is shortened, the whole metamorphosis being accom- plished in the course of only 3-4 days. The larva are pelagic, but very much reduced in organization. Generally they have only two processes, the postoral ones; more rarely a pair of postero-do sal processes are found. For the rest they are very variable as to their shape. The two postoral processes may have coalesced, so that they appear like one single process, and instead of the two postero-dorsal processes there may be only one. In fact, we may find the larva having one, two, three or four processes, or even none at all; but the metamorphosis goes on just the same, whatever may be the number of processes developed. (Fig. 2). There is no vibratile chord, but-a general ciliation of the whole body. The larval intestine is rudimentary ; the mouth opening is very small and there appears to be no anal opening. Evidently the larva does not take any food, but subsists on the yolk SOME JAPANESE ECHINODERMS. 549 A a= aang = aera Whe SA Fig. 2.—Sketches showing the variation in shape of the larva of Zaganum 75 1 decagonale. of the egg. The larval skeleton is, of course, rudimentary, but is otherwise in accordance with the typical skeletal structure of Clypeastroid-larvæ. It is worth pointing out that, in spite of the large size of the eggs, the cleavage is total and quite regular. A feature not hitherto seen in Echinoids, if I remember aright, is that the embryo in the blastula stage, before it leaves the egg-membrane, has the ectoderm strongly folded, much as it occurs in some starfishes (Zwidia a.o.). The forma- 550 TH. MORTENSEN: DEVELOPMENT OF tion of the entoderm takes place not as a real invagination, but more as a strong growth of cells at the oral end, and there is no gastrula mouth. The formation of the enterocele could not be seen in the living embryos on account of their intransparency ; sections are necessary for studying the whole inner transformation. By putting some sand in the dishes, wherein I kept these larve, and thus giving them a natural substrate, I succeeded in keeping the metamorphosed young sea-urchins alive for some time; when this was not done, they perished very soon, assuming the green colour so characteristic of the dying tissue of Clypeastroids. Asteroidea.—I have succeeded in getting the complete develop- ment of Asterina pectinifera and Astropecten scoparius, and the younger developmental stages of dstropecten polyacanthus and Asterias calamaria.” Asterina pectinifera—A special interest is attached to the development of this species. The only species of Asterina, the development of which was hitherto known, is the common European species, the almost classical Asterina gibbosa, which has large eggs and non-pelagic larva. Asterina pectinifera has small eggs, which develop into typical pelagic larve. In the younger stages the larva looks very much like an Astropecten-larva; the preoral vibratile chord is well developed also at the apical end—a character that I have thought to be peculiar to those larve which have no Brachio- laria-stage. Iwas therefore rather surprised in seeing that this larva has a Brachiolaria-stage. The paired Brachiolarian processes are small, with a few papilla at the end; the median process is of the type hav- ing papilla along the edges. The sucking disk is rather large and distinct. For the rest the larva is small and inconspicuous, without colouration. The postero-lateral processes are small and non-contractile. 1) I am indebted to Professor S. Goto for the specific names of these Asteroids. SOME JAPANESE ECHINODERMS. 551 The larve of the two Astropecten-species are of the typical form, and there is no reason for giving their special characters in this preliminary notice. Asterias calamaria at first puzzled me somewhat. In the younger stages it undergoes autotomy and apparently does not propagate sexual- ly. Nearly all the larger specimens opened contained genital organs with large, white, biserially arranged eggs of an oval shape. Having at length found a few specimens with ovaries of the usual Asteroid- structure, I realized that the organs, at first taken for the ovaries of the starfish, belonged to a parasite, most probably a Cirripedian, like that known from other starfishes. I have not, however, succeeded in finding any specimen with the eggs of the parasite so far advanced in development that their real nature could be ascertained. It was only in the last days of my stay at Misaki that I got a few specimens of this starfish with nearly ripe gonads, and only a few of the eggs were quite ripe. I succeeded in getting some few eggs fertilized and in rearing larva only to their first stages. The specific characters ot the larva I can not give; I can not even state definitely whether it has a Brachiolarian-stage. However, there is all reason to expect that it has that stage, like the other species of this genus of which the development has been studied. Of Ophiurans and Holothurians I could not get sufficient ripe material, but only sometimes a ripe male and sometimes a ripe female. Once only I had rich material of an Ophiothrix from deep water, which shed its eggs and sperm of itself. Some of the eggs were fertilized and isolated, but unfortunately they did not develop. Of one species of Comatulids, occurring at the rocky shores close to the station, I got the pentacrinoid stages in a fairly complete series ; but a closer study of this form must be left till my return home. 552 TH. MORTENSEN : Altogether the development of no less than 16 species of Echi- noderms has been studied, more or less completely, during my three months’ stay at the marine laboratory at Misaki. In conclusion I beg to tender herewith my most sincere thanks to my Japanese colleagues, especially to Professor Ijima, for the very kind reception given to me. The China Sea, on board S.S. “ Nikko Maru.” July 26th, 1914. Notes on a Collection of Termites from the East Indian Archipelago. By Masamitsu Oshima Institute of Science, Government of Formosa. With Plates IX and X. In the present paper is given a record of two collections of termites. The first was obtained by Mr. Ryozo Kanehira, expert of the Experimental Forestry Station of the Government of Formosa, during his tour to the Malayan Archipelago in the spring of 1913. The second was obtained at Los-Banos, Luzon, by Prof. C. E. Baker, of the University of the Philippines. The interest of these collections resides not only in the large number of new species they reveal, but also in presenting localities new to the termite collector. I have referred the specimens to the follow- ing twenty-four species, of which nineteen seem to be new to science: 1. Coptotermes dobonicus n. sp. 2. Coptotermes traviens (Hav.). 3. Coptotermes bornensis n. sp. 4. Coptotermes menadoensis n. sp. 5. Coptotermes flavicephalus n. sp. 6. Coptotermes hongkonensis n. sp. 7. Parrhinotermes inequalis (Hav.). 8. Rhinotermes (Schedorhinotermes) longirostris (Brauer). o. Rhinotermes (Schedorhinotermes) tarakanensis n. sp. 10. Zermes (Macrotermes) manilanus n. sp. 11.

Eutermes (Grallatotermes) luzonicus n. sp. 23. Microcerotermes los-banosensis n. sp. 24. Microcerotermes distans (Hav.). Here I express my sincere thanks to Prof. Baker and Mr. Kanehira, both of whom very kindly forwarded to me the interesting materials for examination. The classification adopted in the following is that of Holmgren. Family MESOTERMITIDZE. Subfamily COPTOTERMITIN A. Genus Coptotermes Wasmann. 1. Coptotermes dobonicus nov. sp. (PI.

Remarks.—This species is closely allied to Coptotermes curvigna- thus Holmgren. However, a close comparison of the two species shows several discrepancies. Thus, in C. dobonicus the soldier is provided with much longer head and with antenne which are 17-jointed instead of being 14—16-jointed. In the workers, the most notable difference lies in the number of antennal joints, which in the present species number 16, the 2nd joint being as long as the 3rd, while in C. curvignathus the antenna are 15-jointed, the 2nd joint being much longer than the 3rd. 2.

But in the soldier of C. dornensis the contraction in the middle part of submentum is markedly stronger than in C. travians and the antenne are 14-jointed instead of being 13-jointed. With the workers alone on hand, I have found it scarcely possible to draw a fast line between the two species. 4. Coptotermes menadoensis nov. sp. Soldier and worker unknown.

In the present paper, the Myopsids alone will be considered, re- serving the remaining groups to future publications. The material consisted principally of the specimens in the Museum of the Science College, Tokyo, in addition to which were examined those preserved in the Imperial Museum (Tokyo), in the Fishery Bureau, in the Fishery Institute of Namerikawa (Toyama Prefecture), in the Fishery Experimental Institute of Takashima (Hokkaido), and in the Sapporo College of Agriculture.” Species known to me at present of the Japanese Myopsida group themselves into thirteen genera represented by forty-four species, of which five are doubtful and another five are new to science.

The principal characteristics of this species lie in the tentacular suckers being elongated into a goblet-like shape and provided each with a minute aperture leading into a passage which communicates at right angles with the cavity of the long bell-shaped horny ring (Pl. XI, figs. 3, 4), and in the arm-suckers of males being very unequal in size, several of the marginal series on both sides in the second, NOTES ON THE JAPANESE MYOPSIDA. 591 third and fourth arms being much larger than any other of the suckers (Pls XIs fig.=1), 2. Euprymna similis sp. nov. PI. XI, figs. 5-8. Euprymna morsei, Verrill 1881, p. 417, foot note (Yeddo Bay), P-p=:: Diagnosis. Body oblong, rounded behind as usual in the Sepiolidæ, and slightly longer than broad, the breadth being’ equal to about three-fourths the length; fins subcircular, notched at the anterior attachment to body and slightly longer than half the length of mantle. Mantle joins the head dorsally by a broad ligament, the breadth of which is about equal to the distance from eye to eye. Head a little narrower than body, with slightly prominent eyes. Siphon slenderly conical, nearly extending to the angle between ventral arms; siphonal clasping apparatus elliptical, with a deep median groove for clasping the linear cartilaginous ridge of mantle. Arms rather unequal, the order of length being 2, 3, 4=1; the longest is as long as the mantle; all are slender and taper gradual- ly towards end; the carination of their outer surface indistinct. Suckers somewhat spherical with small aperture and slender peduncle, arranged in four series, except a few basal and terminal ones which are in two series; size of suckers greatly differs in the sexes, In the female they are all equally small, while in the male those of margi- nal series are always larger than those of inner series, and again, those of ventral marginal series are much larger than those belong- ing to dorsal marginal series. The last characterization is especially distinct in the second, third and fourth arms (PI. XI, fig. 5). Horny ring of suckers with entire edges, that in the smaller suckers oval in shape with the long axis transversely directed; that in the larger ones with the upper and lower margins somewhat projecting forward and beak-like (Pl. XI, fig. 6). 592 MADOKA SASAKI: The hectocotylus is the left dorsal, as usual'in Zuprymna, closely resembling in its features that of 4. morsei. There are in the pro- ximal half of the hectocotylus about thirty small and spherical suckers arranged nearly in four series and of which the three or four dis- talmost of the dorsal side are larger than the others. Two nipple- like protuberances project from the suckers at the ventro-proximal part. The distal half of the hectocotylus is provided with about forty unstalked cylindrical suckers which are a little laterally compressed at their end, and are closely arranged in three or four series except in the terminal parts where they are arranged generally in two series (Pla OS A680). Tentacles nearly as long as the mantle, sometimes much longer ; stem flattened on the inner side, rounded on the outer, and the in- ner dorsal angle produced into a thin membrane which distally widens a little; club not expanded, rather short, being of about one-sixth the length of tentacle, pointed at the end; suckers arranged in numerous series, exceedingly small, greatly elongated at base; not goblet- shaped as in £. morsei, but very short and spherical or subcylindri- cal, with minute aperture, the horny edge of which is entire and is surrounded by a broad papillary area (Pl. XI, fig. 7, 8). | Skin smooth throughout, spotted all over with purplish brown chromatophores in alcoholic specimens. Luminous organ developed in mantle cavity. Gladius absent. Type.

The Japanese specimens deviate from Steenstrup’s description in some noteworthy points. According to him, each hectocotylus has only one sucker and no valve at all; whereas, I find in the speci- mens before me that the right hectocotylus is provided with 3-5, and the left hectocotylus with 4-7 suckers (this characterization agrees with that of Appellöf’s specimens from Ternate), and that there exists a semicircular membrane at the extremity of the left hectocotylus. Further, the tentacles are about as thick as the arms and about twice as long as the longest arm, the distal half or three-fourths of the length being taken up by the club, while according to Steenstrup they should be much thinner than the arms, and the club shorter than half the entire length of tentacle.

This species stands in nearest relationship to S. andreanoides Hoyle, but differs from this in the following points: The mantle is twice as large as that of S. andreanoides (as com- pared in fully mature specimens). The horny ring of distal arm- suckers is distinctly denticulated, while in S. andreanoides it presents a smooth edge. The dorsal surface of mantle is marked with large brown spots which are absent in the latter species. The tentacles are less slender, while the shell is on the ventral surface only slightly convex instead of being strongly so and the median groove irregularly running, not straight. 34.

Sepia (Doratosepion) kobiensis, Berry 1912a, p. 423 (Nagasaki; Hakodate ; Hizen ?). Two © specimens obtained by K. Mitsukuri at Enoura, Suruga Prov., April 1884 (Sci. Coll.). Mantle-length 87 mm., 77mm. The characters agree well with Hoyle’s description of the Challenger specimen ; only the posterior end of the fin does not reach the ventral surface of mantle, as it did in the Challenger specimen, but extends straight on toward the posterior mantle-end as usual in this genus. This is a very variable species, as is shown by the fact that the descriptions of it given by Hoyle, Ortmann, Appellòf and Wiilker disagree with one another in some points. The specimens which I examined always showed some discrepancy from the descriptions 618 MADOKA SASAKI: given by the above authorities. Some of the specimens seemed to stand in very close relationship to S. kiensis Hoyle. 37. Sepia (Doratosepion) peterseni Appellöf 1886. Local name: Shishi-ika (Nagasaki).

All these specimens agree closely with the description by Wülker except in the arm-order and in the horny ring of tentacular suckers having 15-20 short and blunt teeth instead of being quite entire. The teeth are sometimes very indistinct, but can always be easily dis- tinguished from the horny papillae of the papillary area. 39. Sepia (Doratosepion) lorigera Wiilker 1910.

Sepia (Doratosepion) longipes sp. nov. PI. XII., figs. 4. 5. Diagnosis. Body large; mantle broad, oval in outline. Arms in male much unequal, very long, the order of their length being I, 2, 3,4, and the longest arm being about twice as long as the length of mantle. Hectocotylization in the distal two-fifths of the left ventral arm; similarly hectocotylized also was the distal one-third 620 MADOKA SASAKI: of the right ventral arm. Arms in female subequal, the order of their length being 2, 1, 3,4; the second arm shorter than mantle- length. Arm-suckers arranged in four longitudinal series in the proximal part of each arm, and in two series in the distal part; horny ring entire. Tentacles thick and long, about twice as long as the ventral length of mantle; tentacular suckers arranged in eight longitudinal series and in markedly oblique transverse rows; their size greatly unequal, four suckers in dorsal submedian series being much larger than the rest; horny ring of the smaller suckers with numerous long teeth on edge. Shell lanceolate, with small discoidal outer cone at the posterior extremity ; dorsal surface convex, with an arched median area marked off on each side by a distinct groove; ventral surface convex in the anterior, and concave in the posterior parts, with a prominent ridge along the median line; last locular boundary of a V-like shape with the pointed end turned backwards; inner cone slightly developed. Locular index about 40. Two 4 and four 9 specimens were obtained by Prof. S. Watasé at Chòshi, Kazusa Prov., on August 18, 1906 (Sci. Coll.).
