tip of tlie snout and the lower orbit. Dorsal fin commencing at a point 

 upon the blind side of the snout in the vertical through the anterior 

 margin of the eye, containing 77-78 rays, the longest somewhat behind 

 the middle of the fin, its length about 7 times in total length. 



Anal fin commencing under the base of the pectoral, comiDOsed of 61 

 rays, the longest post-medial, as long as the longest in the dorsal. Anal 

 papilla prominent. 



Caudal fin rounded, the middle rays about as long as the head. 



Pectorals normally placed, that upon the colored side longest, equal 

 in length to that of the head without the snout. 



Ventral of eyed side on ridge of abdomen, its base rather long but 

 not reaching anal origin; that of blind side farther forward, its length 

 equal to that of its mate, and a little more than one-tenth of the total. 

 Vent at the anal origin slightly lateral. 



Color, gray, hoary above with a few irregularly placed indistinct 

 brownish blotches, none of which me larger than the eye. White below. 



Eadial formula: D. 77-78; A. 61; V. 6; P. 9-11; C. 17; scales, 41. 



The types are numbered 37332 ; they are from station 24:08, Albatross, 

 north latitude 28° 28', west longitude 84° 25', depth 21 fathoms. 



Macrurus caribbaeus, n. s. 



Many specimens of this new species were obtained by the Albatross. 

 The type, number 37333, is selected from a number obtained at Station 

 2377, in the northern part of the Gulf of Mexico, at a depth of 210 

 fathoms. Its length is 290 millimeters. 



In general appearance it resembles ilf. atlanticus, from which it may 

 be quickly distinguished by its sharper and longer ^nout, smaller scales, 

 more advanced second dorsal, and many other less prominent characters. 



The body is normal in shape, its greatest height (44^'") 6^ times in 

 total length. 



Scales moderate, strongly denticulated, about 124 in the lateral line, 

 6 series between origin of dorsal and lateral line, and 15 or 16 series 

 from vent forward to lateral line. 



Length of head (65™"') nearly 4J in total. 



Interorbital area flat, its greatest width (13""'") about 5 times in the 

 length of the head. Postorbital portion of head (21™™) about 3 times 

 in length of head, as long as eye, which is oval, its horizontal diameter 

 (21™™), and If times as long as its vertical diameter (15™™). 



Snout long, thin, diaphanous, with acuminate point, its general form 

 resembling that of M. atlanticus. Nostrils close to the orbit, the pos- 

 terior one much the larger. 



Teeth in both jaws in viliform bands, minute. 



Barbel slender and short, its length (7™™) ^ that of the eye 



The maxilla extends to the vertical through middle of pupil. Length 

 of upper jaw (19™™) slightly more than 3 times in length of head. 

 Length of mandible (26™™) 2^ times in length of head. 



First dorsal with two spines, the first minute, the second smooth.
