tacular niche black. The coloration of the individual described 

 indicates a habitat within reach of the effects of sunlight. 



Nearly eight miles south of Sand Key Light; about 120 

 fathoms. 



Oncocephalus vespertilio. 



Lophius vespertilio Linn.. 17585 S. N.. 236. 

 Snout one-sixth of the total length. Without brown bands 

 or reticulations. Light colored. 



Off Key West, south, in 60 fathoms. 



Oncocephalus radiatus. 



Lophius radiatus Mitch., 181S. Am. Month. Mag., 11, 326. 

 Lophius {MaUke) cubifrons Rich., 1836, F. B. A., Fish., 103.

D. 1+5; A. 4; V. 5; P. 17-18: C. 9. 



As in Halicuta?a, Dibranchus, and allies, a rostral ten- 

 tacle is present in this genus. Among specimens belonging 

 to the Museum of Comparative Zoology there is evidence of 

 the existence of a couple of distinct forms in the West Indian 

 waters. The true H. aculeatus is much the lighter in the 

 ground colors and has brownish reticulations across the back. 

 Two or three narrowish transverse bands of the same color 

 cross the pectorals, and two or three similar bands appear on 

 the caudal, the posterior being darkest. The margins of the 

 fins are light in color. The rostrum is acute; it ends in a 

 spine which turns upward: and seen from above, it is hardly 

 long enough to cover the tentacular niche. Evidently this 

 type belongs to the shallower waters. The localities noted 

 carry its distribution from the Bahamas to the Yucatan Banks > 

 in depths of forty fathoms and less. 



Halieutichthys caribb.eus sp. n. PI. iv, fig. 2. 



D. 1+5; A. 4; V. 5; P. 17; C. 9.
