with the base of the fin, and a broader horizontal black blotch below; two oblique broken black lines 

 across middle of axil; ventral rays in male unspotted, the membranes marked with numerous parallel 

 irregular, V-shaped black lines; caudal with a broad dark bar at base, and one or more irregular bars 

 posteriorly, the latter frequently broken up into finer markings. 



List op Stations. 



Specimens from stations 4778 and 4779 differ from the type in the somewhat smaller eye and the 

 noticeably wider, deeper interorbital space. But as they agree in all other respects, we have considered 

 them as cotypes, as well as the second specimen from the type locality. 



The figure of hlemilepidolus gilberti (Proceedings U. S. National Museum, vol. xxvii, 1904, p. 255) 

 is from the cotype, and not the type. Two additional specimens from Hakodate are in the Stanford 

 University collection. One of these isa male with greatly produced ventral fins. As in the cotype, the 

 ventral rays are conspicuously barred with black, while the membranes are mostly unmarked, and the 

 abdomen is white, with a few faint dusky spots; in females the abdomen is unmarked. In the original 

 description of Hemilepidotus gilberti the last divided ray in dorsal and anal has been counted as two 

 rays. In the three specimens before us two have 21 rays in dorsal, one has 22 rays; two have 18 rays in 

 the anal, one has 17; all have 17 pectoral rays. The pores in lateral line range from 55 to 65. The 

 interorbital is broad and shallow, its width about two-thirds tlie diameter of the large eye. In neither 

 Hemilepidotus hemilepidotus nor H. jordani are the ventral fins produced and papillated in the male. 



Enophrys claviger (Cuvier & Valenciennes). 



Three specimens were secured, ranging from 48 to 57 mm. long, with fin rays as follows: Dorsal, 

 vin-14; anal, 11 or 12; pectoral, normally 18, occasionally 17. It will be noted that the original type 

 and the five additional specimens subsequently reported on (including the three here mentioned) have 

 been of approximately equal size. No specimen of Ceratocottus diceraus as small as these has yet been 

 encountered, but a specimen of Ceratocottus diceraus 114 mm. long has developed all the characters of 

 the adult. While it is highly probable that Enophrys claviger is a distinct species, it is very desirable 

 that the young of Ceratocottus diceraus be obtained for comparison. 



List of Stations. 



Ceratocottus diceraus (Pallas). 



Two specimens, 114 and 155 mm. long were taken with the seine in Avatcha Bay, Kamchatka. 

 This is the type locality for the species, and all specimens which have been described from here lack 

 the bony cross-ridge at posterior border of occiput, which is so strikingly developed in specimens from 

 eastern Bering Sea. This may prove a basis for specific division, but we do not venture upon it until 

 more material is available. 



Ceratocottus litcasi has been recently identified as the young of diceraus by Evermann and Golds- 

 borough (Bulletin Bureau of Fisheries, vol. x.Kvi, 1907, p. 305), but we are unable to accept this decision.
