Color in alcohol: Plain straw-colored, with traces of black pig- 

 ment at tips of outer caudal fin rays. 



Remarks: This new species is distinguished from P. cubensis by 

 having 14 soft dorsal rays instead of 13. It may be distinguished 

 from the other related species by means of the key.

 lat. 9°53' N., long. 59°53' V^., 125 fathoms, Nov. 3, 1957, Oregon 

 station 1983, 9 specimens, 59 to 107 mm. . USNM 185082, off Surinam,

 tion 2013, 1 specimen, 66 mm. USNM 185080, oft" Venezuela, lat. 

 9°24' N., long. 59°41' W., 110 fathoms, Nov. 4, 1957, Oregon station 

 1988, 1 specimen, 77 mm. USNM 185081, oft' Venezuela, lat. 9°39' N., 

 long. 59°47' W.. 100 fathoms, Nov. 4, 1957, Oregon station 1986, 

 9 specimens, 59 to 92 mm. 



This new subspecies from off the Guianas and Venezuela is essen- 

 tially the same (in all important characters) as Pikea mexicanus 

 mexicanus of the Gulf of Mexico, except for the number of gill rakers 

 on the first gill arch — 18 to 21 on P. m. atlanticus and 21 to 23 on 

 P. m. mexicanus. Because of the slight overlap in counts of gill 

 rakers, I prefer to consider the form from off the coasts of Venezuela 

 and the Guianas as a subspecies.
