pelvics. From this they conclude that maturity 

 is probably attained at about 300 mm. The ex- 

 tensive series of G. arae that I have examined in- 

 cludes large numbers of adult, males from the 

 Florida and Central American slope. These are 

 265- to 290-mm. specimens for the most part, and 

 no examples of either sex exceed 330 mm. The 

 specimens from Puerto Rico already mentioned 

 include two adults, a 368-mm. male, and a 352-mm. 

 female. They are not only appreciably larger than 

 any observed from the continental slope but also 

 differ in some body and fin proportions. As 

 shown in table. 6, the Puerto Rican specimens have 

 a proportionally shorter anal fin and differ in 

 other measurements from Florida examples of 

 G. arae.

Holoti/pe.—A female 303 mm. in total length, USNM 

 260468, Fl collected at R/V Oregon, station 3592, lat. 

 09°13' N., long. 80°44' W., in 439-m. depth off the Car- 

 ibbean coast of Panama, May 30, 1962. 



Diagnosis. — A small species of the genus Galeus 

 differing from G. arae in having a comparatively 

 longer anal fin (13.2 to 15.0 percent of total length 

 compared to 8.7 to 13.6 percent in G. arae) with 

 the tip of the anal reaching nearly to the lower 

 caudal origin, separated from it only by a distance 

 less than half the horizontal diameter of the eye 

 as compared to separation by a distance equal to 

 the horizontal diameter of the eye or more in G. 

 arae. The pectoral fins and the two dorsal fins of
