174 "ENDEAVOUR" SCIENTIFIC RESULTS. 



BB. Anal deeply notched, the anterior portion elevated but 

 united with the posterior by low rays. 



E. Teeth on vomer, barbel present. Antimora. 

 EE. No teeth on vomer and no barbel. 



Euclichthys. 

 AA. First dorsal a single ray on the occiput. Bregmaceros. 



EUCLICHTHYS gen. nor. 



Body elongate, compressed; head compressed, with 

 broad septate canals covered by membrane; the upper 

 profile curved, snout rather obtuse. No mental barbel. 

 Head and body covered with scales of moderate size. A 

 band of villif orm teeth in each jaw ; vomer and palatines 

 toothless. Gill-openings extending far forward, mem- 

 branes uniting across the isthmus. Seven branchio- 

 stegals. Pseudobranchise rudimentary, covered with 

 membrane. Gill-rakers of the first arch long and slender, 

 about nineteen on the lower limb. Two dorsal fins, 

 separated by a very narrow interspace; the first high 

 and composed of numerous rays and the margin of the 

 second not deeply incised. Anal divided into two 

 portions; the first short and high and followed by a 

 long series of short rays, increasing in length backward. 

 Caudal fin free. Yentrals with narrow bases, each 

 composed of five free filamentous rays, of which the 

 anterior is divided into two. Pectorals pointed, more 

 than half as long as the head. 



Type. E. polytietnus sp. nov. 



Affinities. This genus belongs to the sub-family 

 Morinae, in which the anal is more or less divided. It is 

 nearest Halargyreus, from which it appears to differ in 

 having the anal fin almost divided into two instead of 

 notched, and in the form of its ventral fins.

 Br. 7 ; D.ii/13, 74 ; A.ii/13, 77 ; P.19 ; V.5. 



The depth (41 mm.) is 6-2 in the total length (255) ; 

 head (51) 5-0 in the same. Orbit (16) 3-1 in the head, 

 and 1-5 in the postorbital length (25). Length of the 

 snout (10) a trifle shorter than the width of the inter- 

 orbital space (10-75) 1-6 in the orbit. Second dorsal 

 spine (36) 1-4, first ray of second dorsal (22) 2-3, third 

 anal ray (25) 2-0, and pectoral fin (39) 1-3 in the head.
