LABORATORY..

ADDITIONS TO THE FAUNA OF CORTEZ BANKS. 



In a trip to the Cortez Banks, subsequent to the one on which 

 the fishes noted in the first part of these notes were collected, 

 Captain Cartel obtained the following species. 



45. Sphyrna zvgaena. (L. ) August. 



46. Echeneis remora. L. On Sphyrna zygaena. 



47. Ditrema atripes, Jordan & Gilbert. A single spec- 

 imen of this species was caught with hook and line in 45 fathoms. 

 August, 1889. 



It differs somewhat from the description of atripes. The lips 

 are black, a black spot at root of mandible. Pectorals hyaline, 

 a narrow black bar at their base, especially well defined on their 

 inner surtace. Ventrals dusky, most so at tip. Upper third of 

 first ten anal rays black. Caudal dark. Sides gray, lighter 

 below, the back being bluish. 



D. X, 22; A. Ill, 28^. Scales 7-70-15. 



From D. orthonotus, this species differs in its arched 

 back and less inclined anal basis. 



48. Chromis punctipinnis (Cooper) — A single specimen. 

 It is undoubtedly identical with Cooper's Ayresia punctipinnis 

 It differs from the specimens described by Jordan and Gilbert. 

 (Syn. Fish. North Am. 611) in having the dorsal XIII, 11 instead 

 of XII, 1 1 and the depth 2? instead of 2j4. Since writing this, 

 Dr. Jordan has examined a specimen in his collection with the 

 dorsal as above XIII, 11 and the depth 2*. 



49. Ophiodon elongatus Girard — One specimen from the 

 Cortez Banks. 



50. Zaniolepis frenatus sp. rov. Type, one specimen, 

 .165 m. Cortez Banks, Capt. Carter, Coll. 



This species is very closely related to Z. latipinnis of Girard. 

 It differs from that species in the less convex profile, the more 

 slender shoulder, lower dorsal spines and color. 



D. XX, 1-12; A. Ill, i6y 2 ; head 4^; depth 6%. 



General form of Z. latipinnis, the body less compressed, the 

 dorsal outline less arched. Profile gently arched; nasal spines
