Head 3| ; depth 5 ; eye 3 ; snout nearly 2 in eye. D. 13 ; A. 17 or 18 ; 

 scales 32-33. Least depth of tail about i greatest height of body. 

 Snout short ; upper and lower profile deeply curved, and with a median 

 crest. Mouth large; length of upper jaw equal to greatest depth of body. 

 Origin of dorsal nearer to tip of snout than to root of caudal ; pectoral 

 fin very long, reaching to at least middle of anal base ; ventral short, 

 not reaching to origin of anal; anal origin under end of dorsal; caudal 

 moderate and deeply forked. A small phosphorescent body on the upper 

 and lower edges of the tail at the root of the caudal ; length of lower 

 patch a little greater than diameter ef eye. 



Mediolateral photophores 2 ; posterolaterals 2, the latter one above the 

 other or nearly so. Precaudals in two groups, 2 -|- 1 or 3 -}- 1, the last at 

 the end of the lateral line. Posterolaterals nearly under soft dorsal. 

 Number of superanals 7 + 6. Three specimens taken by the Albatross from 

 station 2393, in 28 43' N. latitude, 87 14' W. longitude, 525 fathoms.

837. LAMPANYCTUS GUNTHERI, Goode & Bean. 



Head 3; depth 5|; eye nearly 4. D. 13; A. 13; scales 36. Body much 

 compressed. Least depth of tail -J greatest depth of body. Snout short, 

 about i diameter of eye. Mouth oblique, very large, the maxilla extend- 

 ing nearly to angle of preoperculum ; maxilla very little dilated posteri- 

 orly. Length of upper jaw about that of head. Dorsal origin a little 

 nearer to tip of snout than to root of ventral, immediately over origin of 

 ventral and eleventh or twelfth scale of lateral line ; anal origin under 

 the sixteenth scale of lateral line, its base short, about f length of head ; 

 adipose fin present, small, entirely behind the base of the anal ; nine 

 rows of scales between its posterior margin and the root of the caudal; 

 pectorals very long, reaching to above middle of anal ; ventral reaches 

 almost to anal origin ; caudal moderate, well forked. Mediolaterals 3 ; 

 posterolaterals 2. Precaudals 2 -f- 1, the last at the end of the lateral line. 

 Posterolaterals in advance of the first dorsal, forming a gently curved 

 series continuous with anterior half of the broken supra-anal series. One 

 specimen obtained by the Gloucester fleet. (Named for Dr. Albert Giinther, 

 Keeper of the Zoological Collections in the British Museum, and the author 

 of ''monumental works," the foundations of ichthyological work in the 

 last half of the nineteenth century. )
