Selleck, and Fred T. Ross Bureau of Game Conservation California Division of Fish and Game Valley quail (Lophortyx calif or nica) are nonmigratory. Their lives are usually spent within a few hundred yards of the place where they were hatched. Hence, their management and increase is best effected by build- ing up their numbers locally, on the land on which they are to be hunted. How private owners of quail shooting land can be successful in build- ing up quail populations is best exemplified by the Dune Lakes Club quail program at their grounds in San Luis Obispo County. Here, private management has resulted in enormous numbers of quail and a sustained bag yield over a series of years. The Dune Lakes Club is located in the sand dunes and adjacent lands along the southern coast of San Luis Obispo County. The total size of the club is roughly 1,600 acres, although the part suitable for quail and hunted by the owners does not exceed 450 acres (see Fig. 51). Prior to 1928, a group of sportsmen from Santa Maria used the ponds for duck shooting. While a few quail were present, the area was not particularly noted for this type of hunting. When the Dune Lakes Club took over the property in 1928, two moderate-sized quail coveys existed, one near the present headquarters and barns, and one near an old house at the north end. Best local estimates indicate that not over 200 quail existed at this date. No quail hunting was allowed until 1935. During the period prior to 1935, some quail were introduced and extensive feeding and predator control operations were conducted. Starting in 1935, quail hunting was allowed and an accurate record kept of the total numbers shot (Table 1). The increasing yield of birds attracted the attention of biologists of the Division of Fish and Game. Through the kind invitation of the club members, the division was privi- leged to observe and conduct studies of the quail on the club 's grounds during the period from December 1940, to 1943. During the years from 1935 to 1941, the management of quail and ducks was under the direction of one full-time employee of the Dune Lakes Club, aided the year around by one half-time assistant. After 1941, war conditions considerably reduced the manpower employed and the degree of management was much less intense. The Dune Lakes property is a strip about two miles long by one mile wide, consisting of active and retired sand dunes. Roughly half of the 1 Submitted for publication, June, 1945. The authors are indebted to the owners of Dune Lakes, Ltd., Messrs. William Dickinson, Harold Chase, and Peter Bryce, for their cooperation in allowing us to conduct observations on the game at the Dune Lakes Club, and to Messrs. Paul Haddox and L. G. Barker, employees of the club, who aided materially in the conduct of our studies. The Dune Lakes Club was used as one of the experimental areas of Federal Aid in Wildlife Restoration, Project California 6-R, The Management of Valley Quail in the South Coast Counties of California. (167) His CALIFORNIA FISH AND GAME total of 1,600 acres involved is in bare, active dunes. The balance of the area is divided among lakes, marsh, eucalyptus grove, farm land, and brush land. The bare dunes, lakes, and marsh are totally unsuited to quail. During the nesting season some few pairs are to be found in the eucalpytus grove and in the farming ground if the season 's crop affords adequate cover. Generally speaking however, quail are confined to about 450 acres of brush land, or rather to the parts of the brush land which are under intensive management. The actual observed range of fall coveys was 286 acres in 1941. The country surrounding the club is such that few quail are present ; hence the possibility of widespread movement of birds from other areas does not exist. On the entire northwest, west, and most of the south boundaries are areas of bare sand dunes adjacent to the ocean; on the north and northeast boundaries are the truck farms of the Arroyo Grande Valley which support a very low quail population. An extensive series of eucalyptus groves, which are almost a biologic desert, forms most of the eastern boundary. The southeast corner abuts on heavy brush land that supports a low quail population. Fig. 52. View from Dune Lakes headquarters looking over the Bolsa Chica Lake and White Lake. Covey E ranges into the left foreground. The brush at the club covers old dunes, which give a rolling char- acter to the topography. Except on the flat farming land and marsh, the soil is extremely sandy. Lacking humus, it does not hold water, and hence many plants common to brush lands in other parts of the State can not exist. The dominant brush species is heather goldenbush (Haplopappus ericoides). Other common species of brush are tree lupine (Lupinus arooreus), dune lupine (L. chamissonis) , deerweed (Lotus scoparius), coast sagebrush (Artemisia calif or nica) , sea-cliff buckwheat (Eriogonum VALLEY QUAIL UNDER PRIVATE MANAGEMENT 169 parvifolium), black sage (Salvia mellifera) , and California coffee berry (Rhamnus calif omica). Nesting cover is ample, with deerweed and croton (Croton calif ornicus) forming matted clumps. Roosting trees are furnished by willows which grow naturally along sloughs and around the edges of the lakes, and by acacias planted by the railroad company and the club. Annual grasses and weeds are sparse and their green period considerably shortened due to the dry, sandy character of the soil. Prime forage species such as filaree, bur clover, and the annual clovers,, which are the staple quail foods in other parts of the State, are virtually absent at Dune Lakes. Seeds for quail are fur- nished by such species as miner's lettuce (Montia perfoliata) and buck- thorn weed (Amsinckia douglasiana) , which are considered inferior quail foods at best. Rodents were numerous while the investigation was in progress ; meadow mice, white-footed mice, and kangaroo rats formed the bulk of the population. Numbers of seed-eating birds, such as golden-crowned sparrows and white-crowned sparrows, were large during the period of our study. Brush rabbits (Sylvilagus hachmani) were abundant; in 1941, their numbers were extremely high. Early morning counts of up to 100 per one-quarter-mile stretch of road were made in one particularly favorable area during that high year. Principal mammal predators on quail and quail nests at Dune Lakes are opossum, striped skunk, spotted skunk, feral house cat, and weasel. Raccoons, bobcats, and coyotes are taken in limited numbers. Although ground squirrels are present only on areas of good soil, and as such are possible predators on nests and young birds, their scarcity over most of the property suitable for quail makes them a minor factor compared with other parts of the State. Cooper hawks and sharp-shinned hawks, marsh hawks, pigeon hawks, red-tailed hawks, barn owls, and horned owls are the principal raptors. Occasional duck hawks are seen, and rarely a roadrunner is encountered. Gopher snakes are common and considered to be a serious predator on quail nests. The Dune Lakes Club Quail Management Program The active part of the quail management program conducted by the club owners may be summarized under five headings: introduction of wild-trapped quail, artificial feeding, predator control, food and cover plant improvements, and addition to the water supply. The extent of these programs is considered below. Introduction of Quail From time to time during the quail management program, quail were introduced from various sources to bolster the number of native quail on the club. The only definite records prior to 1940 that we were able to uncover were a release of 186 wild-trapped quail from Santa Barbara County in the fall of 1937, a release of 350 game-breeder-reared birds in 1939, and 50 such hand-reared birds in 1940. Several hundred quail were released by the Division of Fish and Game in 1941 and 1942 in order to check the efficacy of such introductions. The results of these introductions will be discussed later. 170 •CALIFORNIA FISH AND GAME Artificial Feeding A unique feature of the Dune Lakes quail management program was the practice of scattering grain on the feeding areas of the various coveys. Steel-cut yellow corn was the commonest grain employed, although whole wheat was scattered to a lesser extent. The amount of feed so used varied from year to year and season to season, but observed limits ranged from six to 12 sacks per week. During the nesting season, from April to July, feeding was cut to the minimum ; in the late summer the amount was gradually increased until by September, up to 12 sacks per week were scattered. The usual yearly quota was 500 sacks costing approxi- mately $1,000 at that time. Feeding was ordinarily done three times per week, Mondays, Wed- nesdays, and Fridays, and the amount of feed used was gauged to some extent by the use by quail and quail competitors. Fig. 53. Feeding quail at Dune Lakes. Feed is scattered along predetermined routes by means of this blower device mounted in the bed of a pickup truck. The low, moderately dense brush apparent in the picture is typical of the quail area. During the first years of such quail feeding the grain was scattered from horseback. Later, feeding was done with the aid of an ingenious blower device mountedjn the bed of a pickup truck (Fig. 53). This consisted of a one-sack capacity hopper which fed the grain to a blower powered by a small gasoline engine. The grain could be blown to the right or left of the truck by turning a deflector in the outlet tube, and was scattered in a band roughly 15 feet wide along the side of the road. Regular feeding routes were traversed by the pickup and the grain was scattered on predetermined strips. The location of the feeding routes VALLEY QUAIL UNDER PRIVATE MANAGEMENT 171 was changed from season to season to draw the quail into areas of easier hunter access. Our evaluation of this whole artificial feeding program will be discussed later. Predator Control Another important feature of quail and duck management was the control of predators. This control was very intensive and included virtually every possible species of mammal, bird, and reptile capable of taking quail. White-tailed kites and ospreys were the only raptors appearing over the area that were granted immunity in the early part of the program. Table 1 is a monthly tabulation of the predator kill for 1939 and 1940 furnished by the club. It will be noted in this table that no specific designation is given to hawks or owls. Our observations in 1941 and 1942 indicate that the hawks taken were principally Cooper hawks, red- tailed hawks, and sharp-shinned hawks in that order. Small numbers of marsh hawks, pigeon hawks, and sparrow hawks were also killed. Prior to our studies, the principal owls taken were barn owls and horned owls. Pole traps, .22 rifles, and shotguns were employed in the raptor campaign, while most of the mammal predators were taken by steel traps. "Weasels and rodents were taken by means of a long box (l'xl'x 10') containing about eight No. 1 steel traps. Holes, two inches in diameter were bored in the sides of the boxes and grain bait was placed inside. The rodents would enter to get grain, and the weasels and an occasional skunk or small opossum would go in to get the trapped rodents. In addition to the predators listed in Table 1, more than 2,000 rodents (chiefly wood rats, domestic rats, various species of mice, kangaroo rats, and ground squirrels) were caught each year mainly in the weasel trap described above. More than 100 snakes were killed annually ; the total was composed largely of garter snakes, with gopher snakes making up most of the balance. It will be noted that the mammal predator take slacked off in October, November, and December. This was due largely to the fact that during the shooting season no trap lines were maintained. From 1941 to 1943, stomachs of all predators killed and retrieved were sent to the Food Habits Laboratory of the Division of Fish and Game. The results of the analyses of some of these stomachs will be found later in the paper. Cover and Food Plant Improvements From time to time during the course of the quail program, attempts were made by the club owners to establish better cover and feed conditions on the property. Cover plants which were introduced included species of Acacia, Eucalyptus, Cytisus (Scotch broom), and Vitis (wild grape). The poor soil conditions and competition with rodents, rabbits, and the native chaparral made the introduction of new cover species particularly difficult at Dune Lakes. All new plantings were protected from rabbit browsing with chicken wire guards. Of the species planted, the acacias showed the most promise; one excellent stand of quail roosts had been developed by use of these trees. The eucalyptus was planted as a wind- 172 CALIFORNIA FISH AND GAME V) i. S o (D -a o CO Q. o> ^ 1— T— re UJ _1 3 3 Of CQ o n < (0 H JC — as * -1 TJ a> 4> £ -a 3 t. Q o u ^H November..

The smaller shrubs such as Scotch broom have not succeeded in establishing much cover ; however, the need for more such shrubby species is very much in question in view of the existing extensive brushy cover on the quail areas. European beach grass (Ammophila arenaria) was planted sometime in the past presumably by the Southern Pacific Railroad in order to stabilize the dunes which were encroaching on their right-of-way. This grass has spread on the southern part of the club's property (Covey A area) and has succeeded in forming excellent escape cover for quail. Several attempts have been made to plant small grains for feed on two relatively level, small fields in the brush area. Milo and several species of millet were used. One planting of proso or Siberian millet was made under our observation. The planting resulted in but little seed and the net benefit to quail was practically nil. The dry, sandy nature of the soil makes the cultivation of such food plants impractical on this area. From 1928 to 1941, grazing was not permitted on the club property. This allowed brushy cover to accumulate and also kept the dunes in check. This exclusion of cattle was without doubt a factor in the increase of quail. A similar area several miles to the south had the same species of brush, but the cover afforded was less than at Dune Lakes due to trampling and browsing. Artificial Watering Although natural watering places were far more abundant than in quail range generally, one well was driven to supply water for one covey whose range in the summer was several hundred yards from the nearest lake. Quail Populations and Quail Harvest That the management methods employed were successful in building up quail populations at Dune Lakes was evident beyond question. After our first visit to the club in 1940, the following notes were made. "At present the quail population on the area is estimated by Mr. Haddox (caretaker) and Mr. Barker, who is now managing the quail, at between 3,000 and 4,000 birds. I (Glading) would be the last one to question their figures since it is practically impossible to get a reliable count of the quail due to their density and the rather even character of the brush. Suffice to say that there is a tremendous population, and that the annual take, plus the supposed crippling loss, places the population density at an extremely high level. ' ' In the fall of 1941, when intensive quail trapping was being done in connection with population and disease studies, counts and estimates were made of the several coveys on the area. At this time, Mr. Barker again estimated more than 3,000 birds and independent estimates by the three authors varied from 2,125 to 2,445 quail prior to the 1941 open season. A Lincoln index census (see below) conducted that fall gave a figure of 2,171 quail for the area. Table 2 will reveal that in 1941 the estimate of more than 2,000 and the Lincoln index result of 2,171 were fairly reliable in view of the fact 174 CALIFORNIA FISH AND GAME that a yield of 598 birds in the bag plus an observed cripple loss of 386 (total hunting season kill = 984) was possible. TABLE 2 Dune Lakes Club 1935-1943 Annual Bag of Valley Quail (Total area available for quail, 450 acres) Year Number of quail in the bag Estimated additional cripple loss (60%)» Estimated total take 1935 249 391 214 377 465 535 598 166 120 149 235 128 226 279 321 359 100 72 398 1936 626 1937 342 1938 603 1939 744 1940 856 1941 957 19422 266 19432 192 1 The estimated crippling loss of 60 per cent was based on observations of the hunt in 1940 and 1941. In 1941, an actual count of 386 unrecovered cripples was made by observers following each hunting party. 2 War years; hunting effort was extremely light. The observed crippling loss of 386 mentioned above was an actual count by Division of Fish and Game employees or the club 's game man- agers, who accompanied each hunter in the field in the 1941 hunt. A limited similar check in 1940 gave a like figure of an added approximate 60 per cent cripple loss. In 1942 and 1943, the population of quail (see below) was consider- ably less due to loss of manpower for management. The bag in these years was even more affected by war conditions since the hunting effort was but a fraction of former years. Cost of Management While no exact figures on the cost of management were available to us, a rough estimate was obtained by observation of the labor, equipment, and materials used. Following is a rough estimate of costs for the man- agement during 1941. Labor — one and one-balf man-yeai's $2,250 Feed 1,000 Ammunition and traps 50 Gasoline, oil, tires, car repairs 100 $3,400 The above estimates do not include original costs of automotive and feeding equipment, taxes, interest on the property, or utilities, and hence must be considered an absolute minimum. Thus, the cost for the 598 birds taken in 1941 was at least $5.68 per bird. While the duck hunting undoubtedly benefited by some of the above expenditure, there was yet another full-time employee, part of whose endeavors were devoted to game management ; hence, the above estimates are a minimum for quail management as practiced in 1941 by the club. VALLEY QUAIL UNDER PRIVATE MANAGEMENT 175 Analysis of the Methods and Results of the Quail Management Census Methods In 1941 and 1942, the population of quail was determined by two methods : direct counts and estimates, and Lincoln index counts. In 1941, familiarity with the coveys gained through three months of intensive quail trapping gave us a fair idea of the numbers of birds in each group. It must be admitted that this direct count is not absolute, since the size of some coveys and the lack of open feeding areas made exact counts impossible. Estimates were gained on the larger coveys mainly by flush counts as the birds flew from feeding strips. Table 3 gives the estimates of the authors for the high year. TABLE 3 Estimated Numbers of Birds in the Various Coveys at Dune Lakes, November, 1941 Observer Covery designation Tota A B C D E F G H 1 300 250 200 450 270 400 250 300 300 375 300 300 525 450 400 75 85 75 320 320 300 150 175 150 2,445 2 2,150 3 2,125 Average 250 373 283 :i'jx 458 78 313 158 2,240 In the fall of 1942, an estimate of 1,200 to 1,400 birds was made by Glading and Ross in November prior to the hunting season. Of the total, 900 to 1,000 were estimated to be in the B, C, D, and E coveys to which hunting was confined that season. Lincoln Index Census In connection with the annual quail hunt in 1941 and again in 1942, Lincoln index counts of the quail were carried out. In this type of census, a number of birds are marked prior to a subsequent hunt or retrapping. Then, by using the ratio of marked birds to unmarked birds later collected, it is theoretically possible to calculate the population that existed during the marking period. The formula used in these calcula- M • T tions is — =— - = X, where M is the number of quail marked, R is the R number of marked quail appearing in the bag, T is the number of quail bagged, and X is the calculated total number of quail in the population. The chief difficulty with this type of census lies in getting an even distribution of marked individuals throughout the area to be censused. In order for the final results to be representative of the area as a whole, it is necessary that the number of marked individuals be in a uniform ratio to the unmarked individuals on the various sub-areas. An attempt to meet this requirement was made in 1941 by trapping and retrapping, comparing the catch for each covey area during four prehunting season quail trapping periods. Thus, separate Lincoln index censuses were run, comparing the second, third, and fourth trapping 176 CALIFORNIA FISH AND GAME periods with the first, and with each other for individual coveys. Thereby, an index of the relative sizes of the coveys was obtained, even though the absolute sizes of coveys may not have been known. The relative sizes obtained by the trapping and retrapping Lincoln index census were weighted and averaged with similarly weighted rela- tive sizes of coveys as estimated in Table 3. The average relative size of each covey thus obtained was used as a basis for the release of sufficient marked quail to even up the number of marked individuals throughout the area. Fig. 54. Baiting- trap with steel-cut corn for quail to be banded and released as part of our study of the characteristics of the Dune Lakes quail population. In the four trapping periods, 506 individual quail were marked and released. To this total, 265 introduced birds were added to bring the marked birds in each covey to the desired number. This made a total of 771 marked quail theoreticallv on the propertv at the start of hunting in 1941. Of the total of 594 quail killed in the hunt and examined by us, 188 M • T 771 x 594 were banded ; substituting in the above formula ^ — = X, — -^ xv loo = 2436. Subtracting the 265 introduced birds from this, gives a figure of 2,171 native birds in the Lincoln index census in 1941. A similar check was made in connection with the 1942 hunt. The Lincoln index figure for this year in these four coveys was 1081. In 1942, however, since the hunting was limited to Coveys B, C, D, and E, the Lincoln index census was confined to that area. Old-Young Ratio Counts Some index of the nesting success and the general condition of the quail population was obtained by examining birds killed and thus obtain- VALLEY QUAIL UNDER PRIVATE MANAGEMENT 177 ing the ratio of old birds (more than one year of age) to young birds ( hatched in preceding summer — less than one year of age ) . The primary wing coverts of the old quail are a plain grey, while those of the young are spotted buff and tan. In 1940, 498 birds taken in the hunt and examined for age char- acters showed a ratio of 365 young to 100 adults. In 1941, 518 native birds examined gave a ratio of 252 young to 100 adults. The figure in 1942 among 166 birds bagged was 141 young to 100 adults. Similar old-young ratio counts were made in connection with the quail trapping conducted in 1941 and 1942. These ratios are too detailed to give completely here, but those taken just prior to the hunting seasons checked well with the above figures. Preseason trapping revealed that a gradual decline in the number of young was apparent from late July until the start of the hunting season, November 15. Nesting Studies As a further check on the population, and on factors affecting it, a detailed study of quail nesting was conducted in the summers of 1941 and 1942. A summary of the fate of these nests will be found in Table 4. It will be noted that the nesting success in 1941, when 19 of a total of 48 nests (39.6 per cent) were successful, was much better than in 1942, when 21 of 114 nests (18.4 per cent) hatched. This lessened percentage of success presaged the lowered population and poor old-young ratio exhib- ited in the fall of 1942.

In Table 4, nests listed as abandoned were largely of two types ; those with few eggs which were abandoned mainly because of some disturbance frightening away the hen, and those having large numbers of eggs laid by two or more hens. The percentage of the latter type of abandonment was high at Dune Lakes presumably because of the high population density. Neither type of abandonment is considered serious, since hens will in most cases continue laying in another nest after abandoning the first. Nests listed as neatly robbed were mainly destroyed by gopher snakes and king snakes. A few actual observations were made of gopher snakes in the act of robbing quail nests. Ground squirrels rob nests in the same fashion as do the snakes. However, since the distribution of squirrels is 17> CALIFORNIA FISH AND GAME limited, they are not considered to be a major factor in nest destruction at the Dune Lakes Club. Those nests listed as "roughly destroyed" were broken up by mammal predators such as skunks, house cats, opossums, etc. This type of predation prevailed on the nests under study. Except for skunks. which have a characteristic manner of sucking the eggs, destruction by other types of mammal predators is hard to ascertain in every case. In a few nests each year the hen had been killed but the eggs were left undisturbed. Mnch of this type of predation is hard to interpret, but some could be attributed to raptorial birds. In 1941, 28 nests that reached the stage of incubation had an aver; 2 clutch of 17.3 eggs: while in 1942, 35 incubated nests had an average clutch of 15.4 eggs. The number of young in the 19 hatched nests in 1941 was 16.4 ; in 1942. the average brood size was 13.9. Predator Studies Studies of the food habits of nesting raptors were made by the "cage- ne»t" method. A complete report of the study as far as barn owls and marsh hawks are concerned will be found in Selleck and Grlading, 1943. These studies revealed that the barn owl's diet, even in this area of extremely high quail density, was more than 90 per cent rodents, and that but a fraction of 1 per cent of all food items taken were quail. Faced with this evidence, the operators of the club dropped the barn owl from their predator list and discontinued pole-trapping since barn owls were the principal species taken by that method of control. The marsh hawk, on the other hand, preyed quite freely on fledgling quail during the nesting season. At marsh hawk nests located in the heart of the quail concentration, mere than 2D per cent of all items brought ^m were young valley quad. Similar techniques were employed to study the food habits of two pairs of Cooper hawks nesting near the club. These hawks ranged only partly over the club's territory, and. hence, the proportion of quail in the diet is probably lower than would be a Cooper hawk's diet on the club proper. Of a total of 64 items brought into these nests. 21 (32.8 per cent) were quail. Stomachs of all predators taken and retrived were saved for stomach analyses. These were turned over to the Food Habits Laboratory of the Division of Fish and Game for analysis. A summary of a part of these will be found in Table 5. Since the entire personnel of the laboratory is now in the armed forces the completion of the remainder of the stomach examination is postponed until after the war. While Table 5 represents but a part of the predators taken during our study, it is indicative of the food habits of some of the more common ones. Of 17 species of predators represented in the analyses, five, the Cooper hawk, sharp-shinned hawk, marsh hawk, coyote, and bobcat, had quail in their stomachs. The size of the sample for most species is too small to draw accurate conclusions. However, additional field observa- tions of predation by raptors indicate that the Cooper hawk, sharp- shinned hawk, and marsh hawk certainly belong on the predator control list. Other observations at the club indicate that the red-tailed hawk. pigeon hawk, and horned owl prey on quail locally and possibly should be included in the control program.

Hubbs Scripps Institution of Oceanography of the University of California Fishes of the genus Prionotus, known as searobins, are common mem- bers of the Atlantic Coast fauna of the United States and are not rare on either side of tropical Middle America, but have very seldom been found on the Pacific Coast of the United States. In fact, only one of the several species known from waters to the southward has been recorded on valid grounds from as far north as California, and only two or three specimens seem to have been collected north of the Mexican border. It is therefore of interest to report the first taking in southern California of a specimen of this species, Prionotus stephanoijhrys Lockington (1881, pp. 529-532). Fig. 62. California searobin, Prionotus stephanophrys : a 121-inch specimen, the first to be recorded from Southern California. Photograph by Paul Williams. Although the species has so seldom been collected in California, the first described or type specimen was taken in October, 1880, in a paranzella trawl "in the tolerably deep water of the region between the rocky islets known as the Farallones, the entrance of San Francisco Bay, and Point Reyes, a rocky promontory some forty miles north of San Francisco." The discription of the species by Jordan and Gilbert (1883, p. 736) and the revisionary treatment by Jordan and Hughes (1886, pp. 329 and 334) were both drawn up on the basis of Lockington 's one example (No. 27048, United States National Museum). No further material appears to have been recorded until 1896, when Jordan and Evermann (p. 487) assigned to this form a range in "deep water, off San Francisco, Point Reyes, and Monterey." Presumably "San Francisco" referred to the type speci- 1 Submitted for publication, May, 1945. Contributions from the Scripps Institu- tion of Oceanography, New Series No. 267. (195) 196 CALIFORNIA FISH AND GAME men and the Point Reyes record was probably based on a specimen (No. 2001) in the fish collection of Stanford University, but no basis has been found to validate the Monterey report. All subsequent published records for Prionotus stephanophrys are for waters south of California. These records need some consideration, since they are surrounded with confusion. The first southern report was by Jordan and Evermann (1898, p. 2161) who added Lower California to the previously assigned range of the species and drew up their descrip- tion from "Mr. Lockington's type, and from two others collected by the Albatross at Station 3041, coast of Lower California. " This station was in Magdalena Bay at a depth of 27 fathoms (Townsend, 1901, p. 407), but the two specimens apparently came from Albatross Station 3039, just off Magdalena Bay, at a depth of 47 fathoms. According to Dr. Leonard P. Schultz of the United States National Museum, Jordan and Evermann apparently transposed the Lower California stations for two species of Prionotus, giving Sta. 3041 for stephanophrys instead of Sta. 3039, and Sta. 3039 (wrongly located "in the Gulf of California") in place of 3041 for quiescens. The next record for P. stephanophrys which I find is that of Ulrey (1929, p. 9), repeated by Cuestra Terron (1932, p. 79), for "Gulf of California," but there seems to have been no basis for this report. Some clerical error was probably involved. Later Breder (1936, pp. 39-40, fig. 13) did report P. stephanophrys from "Angelus" [Angeles] and San Prancisquito bays on the east coast of Baja California, and also from the west coast of Mexico just north of the Guatemala border. Hiyama's figure of "Prionotus quiescens," which he reports (1937, p. 56, pi. 90, fig. B) to be "common in Gulf of Califor- nia," seems to represent P. stephanophrys. The validity of these Mexican reports for P. stephanophrys are open to some doubt, and the Gulf of California records of P. quiescens may all belong with P. stephanophrys. Indeed the two nominal species may prove inseparable. Breder 's identifications, cited above, were made with some hesitancy, and his figure shows several points of divergence from P. stephanophrys, particularly in the almost unspotted first dorsal fin. It is obvious that a critical revision of the Pacific species of Prionotus is much needed. Material for such a study is now rather plentiful, in the fish collections of the New York Zoological Society, American Museum of Natural History, Bingham Oceanographical Collections, United States National Museum, Stanford University, California Academy of Sciences and the Allen Hancock Foundation of the University of Southern California. The one previous report of a searobin from southern California was probably an error. In "A Check-list of the Fishes of Southern Califor- nia and Lower California" Ulrey (1929, p. 9) indicated by symbol that Prionotus gymnostethus occurs in southern California. No Prionotus, however, is mentioned in Ulrey and Greeley's report (1938) on their southern California collections and no specimen of any Pacific species of the genus could be found in examining Ulrey 's collection, now in the Allen Hancock Foundation. Nor is any Prionotus listed in Barnhart's book on the "Marine Fishes of Southern California" (1936). No evi- dence whatever could be found to substantiate the inclusion of southern California in the range of P. gymnostethus. THE CALIFORNIA SEAROBIN 197 To summarize what is known of the distribution of searobins in California, it may be stated that only one species, Prionotus stephano- phrys Lockington, has been recorded on authentic grounds from the State. Only two California specimens, both collected long ago near Point Reyes, have been located in any of the museums that might be expected to have material from the State. The one other locality record, for Monterey, has not been validated. The same species probably occurs on the outer coast of Baja California and in the Gulf of California, and perhaps in still more southerly waters, but there appears to be no valid record for the occurrence of this or of any other species of Prionotus in southern California. That Prionotus stephanophrys does live in southern California may now be affirmed. A specimen 12-| inches in overall length was caught in Santa Monica Bay on October 24, 1944, 64 years after the type was trawled near San Francisco. The new specimen was taken on a hand- line by Michael Waxman four to five miles off El Segundo. According to Hvdrographic Office charts this locality is at approximately Lat. 33° 53' N., Long. 118° 30' 30" W. Here the depth is indicated as about 30 fathoms and the bottom as of sand and gravel. The example, a female with eggs approaching ripeness, is illustrated on Fig. 62. It is deposited in the Natural History Museum of Stanford University (No. 39788). Like other searobins this specimen has the upper parts and sides of the head covered by an armature of bony plates ornamented with granu- lated ridges. These bones, however, are less roughened than in most species of Prionotus and the spines of the head are relatively weak. The main part of the blackish pectoral fin is a large flabby structure resem- bling the "wing" of the distantly related flying gurnard, to which some biologists with free imagination attribute the power of flight. Below this membranous part of the pectoral there are the three separate finger- like rays that are an outstanding feature of the family (Triglidae) in which Prionotus is classified. The southern California example corresponds well with the published descriptions of P. stephanophrys. The main discrepancies — a smaller eye and lower ridges and shorter head spines — are attributable to a dif- ference in size, for the new specimen is an adult and those previously described were only half-grown. For the benefit of ichthyologists who may undertake a critical study of the characters and distribution of Prionotus stephanophrys and other Pacific species of the genus, there follows a detailed description of the new specimen, which is the first adult to be described. The figures in paren- theses are the proportional measurements expressed in thousandths of the standard length (252 mm.) . The body is moderately robust for a gurnard, with the greatest depth (260) below the middle of the first dorsal base. The dorsal and ventral contours are nearly hori- zontal along most of the trunk but then converge backward to the rather slender caudal peduncle (depth, 71). The body throughout is slightly compressed, except above the end of the anal base, where it is as wide as deep (greatest width, across scapular spines, 229). The head is long and massive (length to end of opercular membrane, 390 ; to end of opercular spine, 384 ; to occiput, 291). Then depth of the head below the occiput (230) approximates the greatest width across the preopercular spines. The dorsal contour is gently concave from the tip of the snout to a rather prominent hump in front of the eye, thence less steep and slightly convex to the front of the dorsal (the respective angles formed with the mandibular edge are 51° and 23°). As seen from 198 CALIFORNIA FISH AND GAME above the front of the snout is widely truncated but scarcely emarginate. Measured between the centers of radiation on the suborbitals the width of the snout (169) some- what exceeds the depth (158) below the preocular spine. The snout length (148) enters the head length about 2.6 times. The eye (61) is contained about 2.4 times in the snout ; the bony orbit (95) , 1.6 times. The interorbital is broad and nearly flat, though shallowly grooved on either side of the low rounded median ridge. Its least width (57) is a little less than the length of the eye. The edges of the interorbital are deeply concave (width across preocular bony rim, 61; between preocular spines, 78; between edges of crest posteriorly, 90). The width between the occipital spines (94) is a little greater than the distance (87) from the occiput to the dorsal origin. The least distance from the bony orbit to the preorbital edge (63) barely exceeds the length of the eye. The distance from the preopercular ridge to the tip of the opercular spine is 116 thousandths of the standard length. The head spines are very weakly developed. The lateral margin of the snout is roughened by about 20 tubercular spinelets directed forward. The upper anterior border of the orbit bears indistinct points at the tips of short ridges. The strongest of these points forms the scarcely differentiated preocular spine. The postocular spine has a f ree "projection of less than 1 mm. on one side and of even less on the other side. The edge of the gentle slope in front of the postocular spine has fine, rather indistinct serrations at the ends of tuberculate ridges. Behind the postocular spines the bony margin forms a semicircular indentation and the surface of the head becomes abruptly flatter, but there is no definite transverse groove. There is a rather large bony excrescence at the anterior end of the lateral line a short distance in advance of and slightly below the weak low-lying occipital spine, which does not extend to opposite the dorsal origin. The suborbital margin is very finely and indistinctly serrated. There is no trace of a spine at the center of radiation on the suborbital. Measured from the suture between the suborbital and the preopercle, the length of the preopercular spine (60) almost equals the length of the eye, but the spine is free for only half its length and its tip does not reach the free margin of the subopercle. The indistinct upper opercular spine is flat and far removed from the opercular margin. The outer edge of the thin opercular bone is nearly semicircular between this spine and the flattish, somewhat upturned main opercular spine, which extends slightly beyond the opercular membrane. The mouth is rather large, as the upper jaw (163) reaches slightly beyond the vertical from the front of the orbit and measures 2.35 in the head. The proportional length of the mandible is 175. Fine villiform teeth form rather narrow bands with the following maximum widths, expressed in ten-thousandths of the standard length : premaxillary, 102 ; vomer, 83 ; palatine, 100 ; mandible, 91. The vomerine patch is weakly convex. The gill-rakers on the outer arch number 4 above the angle, with only one well developed, and 19 below, becoming rudimentary at about the tenth. Interpolated between the main rakers are small denticulate tubercles. There are seven branchiostegals. Of the 10 dorsal spines the third and largest is about two-fifths as long as the head. The proportional lengths of the first four spines are : first, 123 ; second, 137 ; third, 163 ; fourth, 155. The others become progressively shorter to the tenth, which is largely imbedded. The front edge of the first spine is finely granulated along the basal half. The soft-rays number 12, with the first one unbranched but articulated. The anal formula is I, i, 9 (the anal formula of Prionotus has apparently been misin- terpreted ; in P. stephanophrys, as presumably in the other species, the first of the two unbranched rays is a true though somewhat flexible spine, whereas the second anal ray, like the first ray of the second dorsal, is a paired and articulated though unbranched soft-ray).2 The proportional lengths of the anal rays are: spine, 42; unbranched soft-ray, 72 ; first branched ray, 88 ; fifth and longest branched ray, 98. The caudal fin, which has 12 principal rays (10 branched), is weakly lunate (length of shortest median ray, 189; of longest ray, 231). The main part of the pectoral fin has a very weakly convex posterior edge from the first to the ninth of the 13 rays, of which the first and the last are simple, the others once branched (the lengths of the rays on the right side — the left fin was injured — are as follows : first, 339 ; seventh and longest, 424 ; ninth, 420, graduating to the eleventh which is 229). The fin extends to above the base of the sixth anal ray. The tips of the free pectoral rays are scarcely swollen and these rays are graduated in length (219, 190, and 158). The pelvic fin (254) extends three-fourths the distance to the anus. 2 The morphological and systematic aspects of fin structure in teleosts are discussed in a recent paper (Hubbs, 1944) and will be further considered in forthcoming papers. THE CALIFORNIA SEAROBIN 199 The thin, weakly ctenoid and rather poorly imbricated scales are probably char- acteristic of the species. They are reduced in size on the nape, near the midline of the belly and about the isthmus, but are rather large near the center of the breast and just behind the pelvic fins. Over the pubic bone medically the scales are slightly imbri- cated, but just in front of each pelvic and over most of the belly they are nonimbricate. A scaleless strip extends from behind the pectoral base to just behind the pelvic base, but the main part of the breast is scaly. The head bears a few scales on the upper part of the subopercle, between the two opercular spines. There are 52 pores in the lateral line. In formalin the body is rather sharply bicolored. The side above the upper edge of the pectoral fin is warm purplish brown with scattered blackish brown specks and small blotches, but is not barred. The lower side and the ventral surfaces are white. A trace of yellow remains on the under side of the head. Above, the head is scarcely spotted, except for obscure speckling on the upper part of the eye. Both dorsal fins and the caudal are dusky purplish with blackish purple spots. Of the numerous spots on the first dorsal the two that are most conspicuous lie, respectively, between the fourth and the fifth and between the fifth and the sixth spines, but there is no large black blotch in this area. The second dorsal bears conspicuous rounded spots, which do not quite reach the upper margin and mostly lie along the front of the rays. These spots are alignable into three or four rows and indefinitely into about two more rows. The spots on the caudal are less distinct and the submarginal ones are elongated, though not fused to form a band. On the upper lobe the spots comprise about five bars, but those on the lower lobe are much less distinct. The anal and pelvic fins are white, with some sooty color on the rays. When folded the pectoral fin is purplish black, but when spread it is dusky purplish with numerous, irregularly elongated blackish spots. The taking of this specimen once again illustrates how incomplete is our knowledge of the fish life of the moderate depths along the coast of southern California. It is quite possible that this and some other species being discovered in these waters may prove of some commercial significance, when federal restrictions that now hold down the coastal fisheries may be lifted. It is reported that in 1943 more than 300,000 pounds of searobins were taken in the commercial fisheries of the New England and North Atlantic states.

Herman Bureau of Game Conservation California Division of Fish and Game The proper management of deer requires a knowledge of many factors which regulate population density. One of these factors is disease. Many diseases occur in deer. As in man, the cause of the condition may be due to microorganisms, parasites, nutritional deficiencies, or general upsets in body activities. Most of these are of a complex nature and their diagnosis requires particular procedures by specialists trained to recognize symptoms and to carry out laboratory tests, microscopic examinations, etc. However, many of the worm parasites that occur in deer are of such a size and nature that no elaborate technique is necessary to discern their presence. This paper is an attempt to describe these parasites in such a manner that the sportsman can recognize them, and, if opportunity presents itself, collect specimens for further examination. Hunters annually harvest large numbers of deer in California and some of these animals could yield much information on the prevalence of disease that would otherwise be almost unobtainable. Very little is known of these worms in deer, as is true as well of other diseases of these animals. In the ordinary course of events compara- tively few deer come to the laboratories of trained specialists for examina- tion. While much can be learned of value from careful examination of a few species, there are many important problems that can be solved only by obtaining data on large numbers. For example, a full knowledge of the geographical distribution of the worm parasites might prove very helpful in suggesting further studies of importance. If one were to attempt an investigation entirely on his own resources it would be neces- sary in many cases to slaughter large numbers of animals in order to obtain factual data of statistical value. Various methods have been attempted by game management agen- cies to obtain the cooperation of sportsmen in securing information nec- essary to govern management of wild animals. This has usually taken the form of questionnaires, sometimes voluntary on the part of the hunter, sometimes compulsory. Such procedures have yielded data which have often been of much aid in deciding regulations in regard to closed areas, bag limits, etc., and have thus contributed much to conservation of the game. Little of this technique has been attempted in disease studies. Dur- ing the past three seasons a number of hunters (particularly members of the Associated Sportsmen of California) have cooperated with the 1 Submitted for publication, June, 1945. (201) 202 CALIFORNIA FISH AND GAME laboratory of the Bureau of Game Conservation of the Division of Fish and Game by procuring blood smears of quail which they shot. "While the numbers thus received are very small in comparison to the complete take of quail, those who have cooperated have added significant data to our studies that otherwise might not have been obtained. It is hoped that the information presented here will inspire some sportsmen to assist in our studies to such an extent as they are able. Eye Worm Thelazia calif orniensis (Fig. 63, A). This is a small round worm, that, in its mature stages, is found on the surface of the eyeball and under the eyelids. It is approximately half an inch in length. It is white in color and if present can be readily seen when the eyelids are pulled back. Besides occurring in deer, this worm has been reported from dog, cat, bear, sheep, and, in three cases, from man. As far as is known at present, this worm parasite occurs only in California. The manner by which it is transferred from one animal to another is not known, although experi- ments seem to indicate it can not be directly transferred by contact. Pos- sibly some insect is involved in the process. In man the worm is readily removed by mechanical means and the patient suffers little more discom- fort than he would if he had a cinder in his eye. Apparently none of the human cases that have been reported have been in hunters. In infected deer there may be only one worm present, but as many as 30 and more have been observed in a single eye. In such heavy cases the infected animal undoubtedly suffers considerably from the irritation and resulting inflammation which causes some impairment of sight. A fuller knowledge of the geographical distribution of this infection in deer might present us with suggestions of a possible transmitting agent. Foot Worm Onchocerca cervipedis (Fig. 63, B) . This round worm, in its mature stages, is found chiefly under the skin of the feet in the region of the hock. It varies greatly in length from two inches to 10 inches. The male worms are much smaller than the females. The worms are whitish, sometimes coiled up, sometimes extended, and may often be mistaken for a nerve fiber or torn muscle tendons. With careful observation they can be seen when the feet are removed at the time the animal is dressed. These parasites are known only from deer, but also may possibly occur in antelope and elk. The geographic distribution of the parasite is not yet fully known, but it has been observed from several areas in California as well as other western states and southwestern Canada. The manner of transmission from deer to deer is not known. It is believed that some losses in deer may result from infection with these worms but much further study is needed to determine the extent of such losses. There have been reports of sore feet resulting from the infection which may make it difficult for the deer to forage for food and make them easier victims of predators. Sometimes small open sores are observed on the skin where the worms may be trying to work their way through to the surface. WORM PARASITES IN DEER 203 Fig. 63.

Body Worm Setaria cervi (Fig. 63, C). This is a long, white, round worm which occurs in the abdominal cavity of the deer. The males are about half as long as the female worms which average about four inches in length. When present in a deer, these worms may be found unattached most any- where in the body cavity and are often removed along with the entrails when dressing an animal. They may be very numerous. 204 CALIFORNIA FISH AND GAME These parasites, which have been reported from deer in many parts of the world, are also known from cattle and from African antelope, but have not been reported from our pronghorn antelope. They have been shown to be transmitted by stable flies. These worms have never been reported from man. Most workers, who have studied this parasite chiefly as it occurs in cattle, are of the opinion that this worm has no harmful effect on the health of the infected animal. Blood Worm Elaeophora schneideri (Fig. 63, C). This is a long, white, round worm which occurs in the arteries of deer. The males are about half as long as the female worms which are approximately four inches in length. In general appearance these worms are much like the previous one described above. The most likely place that a hunter might observe these worms in an infected deer is on the cut surface of the neck when the head is removed from the carcass. The worms may be observed pro- truding from the arteries. Besides deer, these worms have been reported only from sheep. Their effect on the animal and manner of transmission is not known. We are aware of very few cases in deer and only one report from sheep so that much is yet to be learned concerning this parasite. Lung Worms Dictyocaulus sp. (Fig. 63 C). At least two species of lung worms occur in California deer. These are similar in general appearance. They are round, whitish worms which occur in the windpipe, and in the smaller ramifications of the air passages within the lung tissue. The males are slightly smaller than the female worms which are about three to four inches long. It is necessary to slit open the windpipe and its branches or cut into the lung tissue to observe the presence of these worms. These lung worms occur in domestic ruminants and are world-wide in their distribution. They do not occur in man. Transmission is direct ; that is, no transmitting host is required. The eggs of the worms may hatch in the lungs, but are usually coughed up and swallowed and hatch while they pass through the digestive tract of the deer. Some eggs may be expelled in the nasal discharge (sneezed out) or with sputum (coughed out) but most pass out of the animal with the droppings. After the worms pass through developmental stages on the ground they reinfect deer along with food taken into its mouth. When the young worms have passed the stomachs of a deer they penetrate the tissues and eventually reach the lungs where they mature. In heavy infections these worms are capable of inflicting much damage to deer, especially the younger animals. Damage occurs chiefly in the lungs and the infected animals often die from pneumonia. Stomach and Intestinal Worms Ostertagia sp. (Fig. 63, D). These worms occur in the abomasum, or fourth stomach, of deer. They are very small, brownish, round, slender, worms. They occur on the inner wall of the stomach, sometimes in the surface tissue and sometimes buried in small, white nodules or raised WORM PARASITES IN DEER 205 areas. The females are usually less than half an inch in length and the male worms are slightly smaller. These worms can be found by opening the stomach, emptying its contents, and carefully examining the stomach wall. Haemonchus sp. (Fig. 63, E), often referred to as wire worms, also live on the inner wall of the fourth stomach. The male worms have an even reddish color, while in the female the white ovaries are spirally wound around the red intestines, producing the appearance of a barber 's pole. The females average about an inch in length ; the males are some- what shorter. Trichostrongylus sp. (Fig. 63, D). These parasites are small, slender, pale reddish-brown round worms. They usually live in the first portion of the intestine just back of the fourth stomach, attached to the inner surface. They are approximately the same size as the Ostertagia sp. Oesophagostomum venulosum (Fig. 63, F). These small, round, white worms occur in the last portion of the intestine, particularly in the large outgrowth known as the caecum. They may be found either attached to the inner wall or free in the contents of this portion of the digestive tract. The females are less than an inch in length, the male worms are slightly smaller. Because of a number of similarities among the stomach and intes- tinal worms described above, together with several other related worms not mentioned here, the significance of these worms in deer will be dis- cussed as a unit. This group of worms has without doubt caused more serious inroads in the deer population of the coastal counties of California than have all other parasites together. These worms are all blood- suckers, and by living on the blood of the host cause anemia and thus a general weakening of the infected animal. The greatest harm, and thus the greatest losses, occur chiefly among the younger animals, particularly the yearlings. A frequent symptom is diarrhea, or a condition known as scours. Most of these worms also occur in sheep and are most prevalent in deer where they share pasture with these animals. Some species also occur in other ruminants and a few rare cases have been reported from man. However, the chances of a deer hunter becoming infected are extremely remote as can be seen from the life-cycle of these parasites discussed in the following paragraph. The transmission of these worms is direct, requiring no intermediate host. The eggs of the worms pass out of the deer intestine with its drop- pings. The eggs may hatch before they leave the deer. A period of usually two or more weeks is required before the young stages of the worms can infect another animal. In this stage of development the worms thrive best in a moist habitat. They are extremely small and can be observed only with the aid of a microscope. When ready to infect an animal, they climb up on blades of grass to be eaten. Intensity of infection in deer seems to be directly proportional to the amount of grazing done by the animal. In areas where the available browse is limited and the deer are forced to subsist almost entirely on grass, intensity of infection and losses are likely to be high. Losses in yearlings are most common in late winter and early spring when there is an abundance of fresh green grass. 206 CALIFORNIA FISH AND GAME Whip Worm Trichuris sp. (Fig. 63, G). In these round worms the anterior part of the body is long and slender, while the posterior part is much thicker. They may be several inches in length. They live in the cecum of deer with the slender portion of the body usually imbedded in the tissue. The species that occurs in deer is possibly the same as that which occurs in sheep, but probably can not infect man. The life cycle is direct and infection is by mouth. Whether or not these worms cause harm to infected deer is not known. Liver Fluke Fasciola hepatica (Fig. 63, H). This parasite has been reported from a great variety of animals including a number of cases from man. It is of chief importance as a parasite of sheep and cattle. It lives in the bile ducts of the liver and in many areas in California the livers of cattle are condemned for human consumption because of infection with this parasite. The worms are flat and leaflike. In the fresh liver they are reddish and often coiled up in the bile ducts. They can usually be seen oozing from the bile ducts when one slices through the liver. These worms are likely to occur in deer in areas where the infection is common in sheep or cattle. Frequently the appearance of scars on the liver tissue is an indi- cation of the presence of these parasites. Infected livers should be dis- carded and not used for human consumption. The transmission of the liver fluke requires a snail as intermediate host. The eggs of the worms pass out of the deer with the droppings. After a period of development, in water, they hatch as a free-swimming stage which seeks out and penetrates a particular species of snail. Further development takes place within the snail after which the parasite leaves this host to become encysted on blades of grass or sink to the bottom of the water. Infection occurs from eating these cysts. The chief method employed in combatting this infection is the elimination of the snail hosts by chemical means. It is not yet known whether this parasite is as harmful to deer as it is to cattle and sheep. Tapeworms Moniezia sp. and Thysanosoma actinoides (Fig. 63, 1) . These white, ribbon-like flat worms live in the first portion of the intestine and may attain a length of as much as 200 inches in Moniezia. Thysanosoma is much smaller, usually less than 12 inches. These parasites, particularly Moniezia, may cause young deer to be in poor condition and even cause some losses. The worms occur also in sheep, cattle, and other ruminants but have never been reported from man. Bladder Worms Cysticercus, or immature stage of various tapeworms. (Fig. 64.) Tapeworms of the genus Taenia usually require an intermediate host. The adult (tapeworm) usually lives in the intestine of a carnivorous WORM PARASITES IN DEER 207 animal or final host, but as an immature stage (bladder worm) in another species of animal or intermediate host, usually an herbivorous one. The eggs from the adult worms which pass out with the droppings of the animal infected with the adult tapeworm are eaten by the intermediate host. The final host becomes infected by eating the tissue of an infected intermediate host. Fig. fi4. Bladder worms on membrane covering stomach of deer. (Photo by J. S. Dixon) Deer serve as intermediate host for several species of these tape- worms. The commonest occurs as whitish cysts, chiefly on the mesen- teries, the lace-like membrane that covers the entrails of the deer. t They may also occur in the liver. These cysts may vary from the size of a buckshot to that of a small grape. They are thin-walled, contain fluid and a small white body which in the final host becomes the "head" of the tapeworm. The final host of this tapeworm is the coyote or dog. Various other tapeworm cysts occur in deer in other parts of the body. They may occur in heart muscle, lung, or in the flesh. They may be as small as the head of a pin and are always whitish in color. Some of these tapeworms may occur as adults in man, but they are chiefly parasites of cats and dogs. They are readily killed by ordinary cooking procedure so there is no danger in eating cooked meat from an infected animal. However, when cysts (small white spots) occur in the flesh of a deer it would be well not to use this flesh in preparing jerky for human or dog consumption unless the process includes some cooking. The chief con- cern of the hunter should be to avoid feeding the entrails of his deer to his dog whenever the grape-like cysts occur on the mesenteries or in the liver. 208 CALIFORNIA FISH AND GAME Hunter Cooperation Hunters wishing to help in the investigation of these parasites can cooperate by collecting specimens from the game which they kill. The round worms can be preserved in 70 per cent alcohol and the liver fluke and tapeworms in 10 per cent formaldehyde. These solutions can be obtained in any drug store. The general rubbing alcohols can serve. Collected specimens can be sent-to the Laboratory, Division of Fish and Game, Ferry Building, San Francisco. EDITORIALS AND NOTES Fig. 65. Teeth from 310 cm. male spec men of Carcharhinus azureus. THE SHARK, CARCHARHINUS AZUREUS, IN SOUTHERN CALIFORNIA WATERS This note is to record a northern extension of the range of the shark Carcharhinus azureus (Gilbert & Starks) . During September 1942, four specimens of this species were taken in southern California waters. All previous distribution records are from Central American waters. We have received no additional California records up to June 1945. The species is discussed at some length by Beebe and Tee- Van who refer to the species as Eulamia azureus (Zoologica, vol. 26, part 2, pp. 109-110, 1941). The California specimens agree in all respects with their descrip- tion. In using the name Carcharhinus in- stead of Eulamia we are following gen- eral precedent and the advice of Dr. Carl L. Hubbs and Mr. W. I. Follett, both of whom have spent some time untangling the involved synonomy of the genus. Probably the matter will have to be finally settled by the International Commission on Zoo- logical Nomenclature. Data on the individual specimens follow : 1. Male, 305 cm. total length. Taken in soupfin shark (Galeorhinus zyopterus) gill net, set in three to ten fathoms on the south side of Santa Catalina Island between September 10 and 13, 1942. Liver weight, 23 pounds. 2. Male, 310 cm. total length. Taken in purse seine catch of horse mackerel (Trachurus symmetricus) one mile off the east end of Anacapa Island, September 17, i942. 3. Male, about the size of those above. Seen on a purse seiner in Los Angeles Harbor September 18, 1942. As the vessel was leaving the dock at the time, it was impossible to obtain a definite catch locality. 4. Immature female, 197 cm. total length, 82.5 lbs. total weight. Taken in soupfin shark gill net, set in three to ten fathoms on the south side of Santa Catalina Island between September 16 and 20, 1942. Liver weight, four pounds. Teeth from the 310 cm. male are illustrated in Fig. 65. These teeth have been turned over to the Natural History Museum at Stanford University. Their museum specimen number is 40091. — D. H. Fry, Jr. and P. M. Roedel, Bureau of Marine Fisheries, California Division of Fish and Game. June, 1945. (209) 210 CALIFORNIA FISH AND GAME TWO UNUSUAL FLATFISHES FROM MONTEREY BAY Within a period of one week, two unusual flatfishes were taken from Monterey Bay. One of these was a California halibut, Paralichthys calif ornicus, 20 inches in total length, and the other a starry flounder, Platichthys stellatus, 12-| inches in total length. Both of these specimens were totally dark on the underside as well as on the top side. In addi- tion, both had an anterior hook to the dorsal fin and one eye incompletely rotated from the opposite side (see Fig. 66). It is not unusual to find a flatfish occasionally with partial coloration on the white or blind side, with no other abnormalities. But, total or almost total ambicoloration accompanied by the above abnormalities is quite rare. Fig. 66. Top view of head of ambicolored California halibut showing anterior hook to dorsal fin and one eye in partially rotated position. The total length of specimen was 20 inches. An ambicolored starry flounder, 12J inches in total length, taken about the same time and in the same general locality in Monterey Bay showed the same characteristics. The California halibut was taken in 25 fathoms of water off Moss Landing by the vessel ' ' Falcon ' ' while dragging on December 28, 1944. The starry flounder was taken in the same locality by the vessel "Riso Bros." on January 4, 1945. Both catches were unloaded at the General Fish Corporation, Monterey. Cottardo Loero, manager of the concern, saved the specimens upon noting their peculiarities. The specimens have been turned over to Stanford University for permanent keeping. E. W. Gudger of the American Museum of Natural History, New York City, has been working on unusual fishes for 17 years. During this EDITORIALS AND NOTES 211 time he has noted a number of flatfishes with partial coloration on the blind side but with no other apparent abnormalities. However, he has noted only a few cases where there was complete coloration, or nearly so, on both sides, accompanied by the hooked dorsal fin and partially rotated eye. The few cases reported by Gudger have been from the Atlantic seaboard. The complete coloration of both sides of the two flatfishes mentioned may be associated with the incomplete development of the head. That is, development appears to have been arrested at a post-larval stage when pigmentation still persisted, strongly, on both sides. However, this does not explain partial coloration of the under side when development of the head and the rest of the body appears to have been perfectly normal. Nearly all experiments concerning color in fishes show that, in normal animals, paling and darkening of the skin is due to the response of chromatophores to stimuli received through the eyes. — J. B. Phillips, Bureau of Marine Fisheries, California Division of Fish and Game, May, 1945. LATE SPRING SPAWNING OF CHINOOK SALMON (ONCORHYNCHUS TSCHAWYTSCHA) On May 5, 1945, Dr. H. W. Wilkinson of San Jose and I were fishing on the Sacramento River below the U. S. 99 Highway bridge at Redding. Two dark salmon were noted rising regularly at the same spot on a big riffle. My curiosity was aroused and a spinner was cast out above the two fish. On the first cast a small salmon about 20 inches long fol- lowed the spinner almost to shore but refused to take it. This was a dif- ferent fish from the two observed rising. On a succeeding cast there was a light strike and the fish hooked at the spot of rising. Very little fight was shown by the fish which was easily brought in and beached in shallow water. As soon as the fish fell over on its side, ripe eggs began pouring out. It proved to be a female Chinook or king salmon (Oncorhynchus tschawytscha) about two-thirds spawned out. This was checked by the count of 16 rays in the anal fin and other characters. I judged the fish to weigh about 14 pounds. The lower portion of the caudal fin was badly frayed and the soft tissue of the anal fin was nearly all gone, leaving the rays exposed. There were many creamy white blotches showing on the rear third of the fish. She was immediately released and a few minutes later was noted back at the same location in the riffle with the other larger dark fish, which I took to be a male from its general shape although the snout did not appear to be as greatly developed as are some fall run males. To my knowledge the occurrence of late spring Chinook salmon spawning has not been heretofore reported from the Sacramento River. — Donald D. McLean, Bureau of Game Conservation, California Division of Fish and Game, June, 1945. 212 CALIFORNIA FISH AND GAME TWENTY-FIVE YEARS AGO IN CALIFORNIA FISH AND GAME The leading article in California Fish and Game for October, 1920, was "Distribution of the Golden Trout in California" by S. L. N. Ellis and H. C. Bryant. It covers the years from 1876 to 1919, and tells how members of our Bureau of Patrol, members of the Sierra Club, and interested individuals caught golden trout from the small streams which were their native habitat and transported them by pack stock to other streams and lakes in the nearby High Sierra. It was toward the end of the period covered by this report that the Division of Fish and Game undertook the artificial propagation of this trout. An egg-taking station was established on the Cottonwood Lakes above Lone Pine, and in 1918 the first successful shipment of eggs was made to the Mt. Whitney Hatchery. Production of trout from this source continued annually through 1941, the policy being to confine dis- tribution to the High Sierra from the Yosemite south, although isolated plants were made in other parts. Barren lakes were utilized wherever possible in order to prevent interbreeding with other species, and in these lakes the golden trout flourished. With the war came limitations on manpower which made operation of the Cottonwood Lakes Station dif- ficult, and at the same time it was felt that the golden trout had so well established themselves in most of the remote, lightly fished waters where they had been planted that stocking was not essential for the time being. Conditions after the war will determine whether it is necessary to resume hatchery production of these fish. It is now believed that there are not more than two distinct species of golden trout, Salmo whitei from Soda Creek tributary to the Kern from the west, and Salmo aguabonita from Golden Trout Creek and the head- waters of South Fork of Kern. Salmo roosevelti has been shown to be indistinguishable from the latter form, and this name is therefore not valid. All species of trout have the tendency to vary in appearance under different conditions, and in the golden this is demonstrated in extreme form. In its native Golden Trout Creek it rarely grows over 10 inches in size, and retains throughout life the oval, purplish patches along the side called "parr marks." Transplanted into barren lakes, it may reach a weight of several pounds, and, perhaps as a result of its rapid growth, loses the parr marks at an early age. Fish from the two habitats placed side by side would not be recognized by the uninformed as being of the same species. — Brian Curtis, Editor, California Fish and Game, July, 1945. IN MEMORIAM W. L. HARE Warden W. Les Hare passed away on July 13, 1945. He had been in poor health for the past several years, and became seriously ill while stationed at Elsinore. Suffering hemorrhages, he was taken to the Riverside Hospital, Riverside, California, where the end came. He was 65 years old. Les was employed as a warden at various times from 1917 to 1922, and as a full-time warden from 1927 until his death. He was a willing and conscientious worker and intensely interested in all fish and game matters. His funeral was largely attended by employees of the Division in southern California. He leaves a son, Marquis, to whom the Division extends sincere sympathy. — L. F. Chappell, Chief Bureau of Patrol, California Division of Fish and Game, September, 1945. VICTOR E. VON ARX Warden Victor E. Von Arx died at his home in Santa Rosa on August 21, 1945, at the age of 69. His service with the Division of Fish and Game started in August of 1920 and he had just completed 25 years as a member of the Bureau of Patrol. He would have been eligible for retirement in March of 1946. Most of his service was in Sonoma and surrounding counties. He was a highly respected citizen of these communities, always friendly, loyal to his organization and regarded as one of the most efficient wardens on the force. His health had not been the best for the past two years, but he carried on a full working schedule until shortly before his final illness. Very sincere sympathy is extended to Mrs. Von Arx and his family by the Division of Fish and Game. — L. F. Chappell, Chief Bureau of Patrol, California Division of Fish and Game, September, 1945.
