 Blake Collection. By G. Brown Goode and Tarleton H. Bean. 



The following descriptions relate to species first brought to light by 

 Mr. Agassiz during his earlier " Blake " explorations in the Gulf of Mexico 

 and the Caribbean Sea, in 1877, 1878, and 1879. Several other species 

 have been diagnosed, and their characters will soon be published. 



Aphoristia marginata, n. sp. ^ 



The species is described from a specimen collected by the steamer " Blake " 

 at Station CLXXi. with a specimen from Albatross Station 2376 as a collateral 

 type. 



The extreme length of the type is 102 miUimeters. 



The body is slender lanceolate in form, its greatest height contained 4| times 

 in the extreme length. The scales are moderate, strongly and sharply denticu- 

 late, the surface ornamented with many lines and striations, which are so 

 arranged as to form a semblance of median furrows ; 88 to 90 scales in a longi- 

 tudinal series, 34 in a transverse series. 



Jaws and snout covered with scales. 



The length of the head is contained 5| times in total length. The length of 

 the snout in that of the head 4-^ times, and equal to the diameter of the upper 

 eye. 



The eyes are moderate, close together, the upper very slightly in advance. 

 The nostril, in a long, slender tube, nearly midway between lower eye and tip 

 of snout. 



Mouth moderate, oblique, curved, its posterior angle beneath the anterior 

 margin of the pupil of the upper eye ; its length of gape in that of head 4^ 

 times, and 5 times in greatest height of body. Dentition feeble. /''
