274 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



A full series of the specimens taken, including the types of the new 

 species, has been presented to the Leland Stanford Junior University 

 through the Hopkins Seaside Laboratory, under the auspices of which 

 Mr. McGregor carried on his work. The rest of the collection has been 

 sent to the British Museum, the museum at Vienna, the TJ. S. Fish 

 Commission, and the TJ. S. National Museum. 



Family GALEID^J. 



1. Mustelus lunulatus Jordan & Gilbert. One specimen, a yard long, from Ensen- 



ada, Lower California, March 6. The first dorsal fin is lower and both dor- 

 sals and pectorals less incised than in the type of the species. The snout is 

 also somewhat shorter and broader. All these may be characters of increased 

 age, as the specimen is larger than any of those originally described. 



2. Carcharhinus platyrhynchus (Gilbert). Two young individuals from Clarion 



Island. 



3. Galeorhinus zyopterus Jordan & Gilbert. One young example from Ensenada 



harbor. 



Family DASYATIDiE. 



4. Urolophus halleri Cooper. One specimen from Ensenada, Todos Santos Bay. 



Family OPHICHTHYIDiE. 



5. Ophichthus triserialis (Kaup). One example, 25 inches long, Abreojos Point, 



Lower California. 



6. Myrichthys pantostigmius Jordan & McGregor, new species. (Plate 4.) 



Head 4£ in trunk; head and trunk 1£ in tail; cleft of mouth 3 in head; 

 eye 2£ in snout, which is 5 in head. Pectorals 2 in snout. Anterior nasal 

 tube equal to eye. Color olivaceous, with distinct rows of roundish blackish 

 spots, some oblong, smaller on head and covering whole belly ; 39 spots in 

 dorsal row, these spots usually alternating each with its fellow on the other 

 side of dorsal, but sometimes opposite; spots of second row usually opposite; 

 spots of third row smaller and more numerous, extending from the cheeks to 

 opposite the vent, thence running along base of anal, not running on fin, most 

 of this row little more than half length of snout; two rows of smaller spots 

 along belly from gill-opening to front of anal ; spots on nape rather large, on 

 head larger and more numerous than in Myrichthys xysturus. Pale color of 

 head reduced to reticulations ; chin and throat spotted as much as head ; no 

 pale centers to any of spots; dorsal without spots or with only a few which 

 come up from back ; from beginning to end the dorsal has a broad black mar- 

 gin about one-third height of fin ; anal mostly pale, but having some black 

 markings toward tip; pectoral with upper half jet-black — a white margin 

 posteriorly — a small black spot in lower corner. 



One specimen, 20 inches long, from Clarion Island; type number 5710, 

 Leland Stanford Junior University Museum; 



This species is distinguishable from all others by the great number of 

 spots of small size and without pale centers, the black edge of dorsal, the 

 black spot on the rather large pectoral, and especially by having the belly 

 spotted as much as the other parts.

 11 in head. Teeth in each jaw in a single series ; palatine series either par- 

 allel with these or divergent ; no distinct: canines ; teeth comparative! v small j
