dorsals is twice the length of the base of the first, the second beginning in the 

 perpendicular from the fifth ray of the anal. 



The anal is about three times as high as the second dorsal. The vent is 

 under the 30th scale of the lateral line directly in advance of the anal, and 

 at a distance from the ventral considerably greater than the length of that fin, 

 in this respect differing widely from M. Bairdii. 



Distance of pectoral from snout slightly more than the length of the head. 

 Its length is less than that of the dorsal spine, and slightly more than half its 

 distance from the snout. Its insertion (upper axil) is in the middle Line of the 

 body. 



Insertion of ventral under that of pectoral, and slightly in advance of that 

 of dorsal. Its first ray is not greatly prolonged, and is about half as long as 

 the distance of the fin from the snout.

A specimen was taken at station 306. The species has been sent to the 

 National Museum by Gloucester fishermen.

10. Coryphaenoides carapinus, new species. 



Several specimens were obtained from various stations of the "Blake." 

 Most of these had their tails broken off, and all of them were completely de- 

 nuded of scales, — a natural consequence of their passage in the nets from the 

 ocean depths. By a happy chance, two scales were found attached to the base 

 of the dorsal fin of one of the larger individuals, thus enabling us to determine 

 the general character of the covering of the body. The description of this 

 species is necessarily meagre. 



Diagnosis. — Scales 22 to 24 in a transverse series ; (the .position of the 

 lateral line cannot be deterndned, but there appear to be four above it ;) the 

 scales are oval, membranous, without armature, and rather large. The first 

 ray of the dorsal is very short ; the second, compressed anteriorly and serrated, 

 with slender teeth closely appressed and bent upwards. Its length is equal 

 to the length of the head, and is greater than the height of the body. This fin
