FISHES FROM BERING SEA AND KAMCHATKA. 87 



the ground color .ntensified in front of each spot; a dusky spot on the middle of the base of the pectoral; 

 a dark streak running obliquely across the cheek from the edge of the preopercle through the eye and 

 thence nearly vertically across top of head at front of eyes, separating the paler portion of the head 

 from the ground color above. Rare in the tide pools of Bering and Medni Islands. 



Pholis dolichogaster (Pallas). 



Taken at Medni and Bering Islands and at Petropavlovsk, Kamchatka; not abundant. 



Pholis omatus (Girard). 



Vancouver Island (Union Bay), Unalaska, Atka, Agattu, Attn, Medni, and Bering Islands; 

 abundant at all shore stations as far west as the Commander Islands; not known from Kamchatka or the 

 Kuriles. 



Alectrias alectrolophus (Pallas;. 



Specimens were taken at Unalaska, Attu, Medni, and Bering Islands, Petropavlovsk, and at stations 

 4777 and 4778 on Petrel Bank; depth 52 and 43 fathoms. 



The interorbital crest does not develop uniformly in this species, in a specimen 85 mm. long from 

 Unalaska the crest is undeveloped; normally the crest is fully developed in specimens of this length. 



ALECTRIDIIIM, new genus (Blenniidae). 



Body compressed, with embedded scales posteriorly; lateral line absent. Teeth on jaws, vomer, 

 and palatines; the teeth near the tip of the jaws somewhat enlarged but scarcely caninelike. Gill 

 membranes united, slightly connected with tlie isthmus, with a broad free fold behind; branchi- 

 ostegals 5. Dorsal fin composed of flexible spines anteriorly, of rigid spines posteriorly; no anal spines; 

 no ventral fins. Closely related to Alectrias but diflering in the absence of the lateral line. 



Type Akclridium aurantiacum, new species.

Alectridium aurantiacum, new species. (Fig. 31.) 



Type 83 mm. long, from Nikolski, Bering Island. 



Head 15.5 htmdredths of length without caudal; depth 13.5; eye 3; maxillar>- 6.2, snout 3.2; 

 pectoral 5; caudal 10. Dorsal Lxu; anal 43; pectoral 11. 



Head and body compressed; interorbital and occipital region compressed, forming a sharp ridge; 

 the ridge represented on the anterior part of the interorbital and the snout by a fold of skin or crest; 

 mouth slightly oblique; lips thin; maxillary extending to vertical from posterior margin of eye. 

 Scales small, present only on the posterior half of the body, embedded in the skin; lateral line 

 absent; a series of pores around eye, extending backward to above opercular flap; another series 

 along edge of preopercle; a few on top of head. 



Origin of dorsal above base of pectoral; last spine shortened, connected to caudal; origin of anal 

 nearer tip of snout than base of caudal by a distance equal to head and pectoral, the last ray connected 

 for half its length to base of caudal; caudal rounded.
