ot jamaicensis. The tibiae average 20.8 against 21.9 mm. in the 

 same series. 



Foot. — The foot is narrower and lightly built throughout, while 

 in jamaicensis the foot is heavier and each toe is individually 

 broader. 



Color. — Apparently the same as jamaicoisis, but no skins have 

 been examined. 



Skull. — Identical with A. jamaicensis, but very slightly smaller. 



Teeth. — The second upper premolar is broader and with a heavier 

 internal shoulder, the teeth being actually broader than jamaicensis, 

 though the latter possesses a slightly larger skull. 



Remarks. — This form is easily separated from the Jamaican 

 animal by the lighter, slenderer foot and the shorter forearm. 



Specimens Examined. — Seven alcoholic specimens. 



Santiago de Cuba. One (type). Tlie Academy of Natural 

 Sciences of Philadelphia.

Comparative measurements. 



A short time ago Dr. J. Percy Moore, of the University of 

 Pennsylvania, submitted to me an alcoholic specimen of a species 

 of Nyclinomus from the Bahamas. A hasty examination and com- 

 parison with available material revealed the fact that it represented 

 a distinct form. Later, after speaking to Mr. G. S. Miller, Jr., 

 of the U. S. National Museum, regarding the animal, he kindly 

 turned over to me a series of skins of this species from Little Abaco, 

 which had been submitted to him by the British Museum. A 

 series of Cuban specimens were also forwarded which greatly facili- 

 tated comparison.
