FISHES FROM BERING SEA AND KAMCHATKA. 



71 



Head 29 hundredths of length of body without caudal, depth 23; disk 20- eye 4.5; snout 11; gill 

 opening 5.5; maxillary 11. Dorsal v-26; anal 25; pectoral 31. 



Body robust anteriorly; deepest in front of first dorsal. Head deep and wide; width a little greater 

 than depth; occiput swollen; profile rising rapidly from the eyes, snout short, rounded ; mouth narrow, 

 almost entirely transverse; maxillary reaching vertical from front of eye. Teetli strongly trilobed, 

 arranged in about 8 oblique rows in the half of each jaw. Anterior nostril in a tube; posterior nostril 

 with a raised rim. Gill opening entirely above the base of the pectoral iin. 



First dorsal low, separated from the soft dorsal by a shallow notch; anal similar to second dorsal; 

 dorsal and anal slightly joined to caudal; caudal composed of 12 rays; pectoral with a shallow notch 

 separating the two lobes. Disk large, its anterior edge under posterior margin of orbit; distance from 

 tip of lower jaw to disk two-thirds diameter of disk, 2'. 2 in head. \'ent nearer disk than origin of anal; 

 distance from disk to vent 4.66 in head. 



Color dark slate, paler on the sides of the body; a light bar across base of caudal and posterior edge 

 of dorsal and anal. 



Collected in the tide pools on Unalaska, 



Cyclogaster (Neoliparis) callyodon (Pallas). 



This species is common among the Aleutian Islands. 

 Atka, Agattu, Attn, and Bering Islands. 



Specimens are usually spotted with fine black specks and have the fins barred, even in the young; 

 they are slender, have the anal fin not continued beyond base of lower caudal ray, the anus is nearer 

 disk than front of anal, and the dorsals are always distinct. In two specimens fin rays are as follows: 

 Dorsal v-28, anal 26, pectoral 29; dorsal v-28, anal 25, pectoral 30. In none of our specimens is there 

 present the silvery streak on side of head described by Pallas.

Cyclogaster (Neoliparis) micraspidophorus, new species. (Fig. 16.) 



Type, a male, 73 mm. long, from Nikolski, Bering Island. 



A tide-pool species, known only from Agattu and Bering Islands. On account of the character of 

 the gill opening, this species is apt to be confused with iV. mucosus (=A^ flora). It differs from the 

 latter species in the shape of the body, greater depth, more swollen cheeks, slightly larger disk, and 

 the coloration. 



Dorsal vi-25; anal 25; pectoral 31. Head 27 hundredths of length without caudal; depth 24; ven- 

 tral disk 17; eye 3.7; snout 11; gill slit 6.5; maxillar)' 9. 



Body deepest at front of first dorsal; dorsal outline sloping gradually to middle of second dorsal, 

 whence it slopes more rapidly to the caudal . Head rather heavy ; occiput swollen ; profile depressed over 

 eyes; cheeks swollen. Mouth terminal. Teeth trilobed, arranged in about 8 oblique rows in the half of 

 each jaw. Snout depressed, evenly rounded. Eye small. Posterior nostril with a low flap in front. 

 Gill slit extending down in front of about 5 pectoral rays. Body and fins with scattered "thumb- 

 tack" prickles, these absent on the lower surfaces and the snout.
