182 Dr. A. Guntlier on Deep-sea Fishes 



Caudal emarginate. Gill-openings very wide, the gill-mem- 

 branes being separate from each other and from the isthmus. 

 Eleven or twelve branchiostegals. Gill-laminse well deve- 

 loped, separate; gill-rakers tubercular; pseudobranchiaa well 

 developed. 



Bathysaurus ferox. 



D. 18. A. 11. P. 15. V. 8. L. lat. ca. 120. 



Adipose fin none. 



East coast of New Zealand, 1100 fathoms. 



Bathysaurus mollis. 

 D. 15. A. 11. P. 15. V. 8. 



Adipose fin present. Rays of the fins, especially the front 

 rays of the dorsal, rather elongate. 



Middle of South Pacific ; off Yeddo : 1875 and 2385 fa- 

 thoms. 



Chlorophthalmus nigripinnis. 



B. 7. D. 11. A. 9. L. lat. 50. 



Similar to the Mediterranean Chlorophthalmus Agassizii, 

 The length of the head is contained thrice and three fourths in 

 the total length (without caudal) ; the eye is large, two fifths of 

 the length of the head, and three times the width of the interorbital 

 space. The distance of the adipose fin from the dorsal equals 

 that between the latter and the front margin of the eye. Teeth 

 in the jaws, on the vomer and palatine bones, in very narrow 

 bands. Pectoral rather shorter than the ventral, which ex- 

 tends far beyond the vent, the vent being much nearer to the 

 ventral than to the anal. Silvery, with some very indistinct 

 darker spots on the sides of the body ; top of the dorsal and 

 extremity of each caudal lobe deep black. 



OiF Twofold Bay, 120 fathoms. 



Chlorophthalmus gracilis. 



B. 10. D. 11. A. 11. L. lat. 60. L. transv. 6/7. 



The length of the head is one fourth of the total length 

 (without caudal) ; the tail being slender, the distance between 

 the end of the anal and the root of the caudal is not very much 

 less than the length of the head. Distance of the adipose fin 

 from the dorsal equal to that between the latter and the front 

 margin of the eyes. Snout depressed, flat, with the lower jaAv 

 prominent j interorbital space broad, more than the vertical
