of the paper quoted above, Allen writes tliat " A. coryV' " differs 

 greatly from all others [all other forms of the '■^ ■perspiciUalus'''' 

 section] in colour and in the distribution of the fur on the 

 forearms, which on the dorsal surface extends densely in a broad 

 band along the humeri and over about the proximal thii'd of the 

 forearm bones.'' There must be some mistake here ; the distribu- 

 tion of the fur on the forearm in St. Andrew's specimens is as 

 described by Allen, but so it is also in all other individuals of 

 A. j. ja'inaice7isiSj from any place, I have seen, and, in fact, in all 

 other races of A . j. jamaicensis. 



J. A. Alien s A . insularis, 1904. — Type locality : St. Kitts, West 

 Indies. '' Based on a single alcoholic specimen, a very old male, 

 in excellent preservation, but with the skull badly broken. In 

 external measurements it agrees very well with. A. jamaicensis, 



The skidl, however, in A. insularis is much larger than 



in A. jamaicensis, the width across m--m" being 1 mm. (about 

 one tenth) greater, and the rostrum at the base of the canines is 

 also a millimetre Avider, or about one eighth wider. This indi- 

 cates a. much larger and more massive skull than in A . jamai- 

 censis, while the external measurements are about the same." 

 " Dorsal surface pale reddish brown, paler below ; membranes 

 pale brown ; no head stripes." Width of skull across m" 1 3 ; 

 width at base of canines 8'6 ; upper tooth-row (c-m^) 11 ; lower 

 tooth-row 11 ; forearm 61 ; third metacarpal 58 mm. 



The specimen described by Allen is, in certain respects, a little 

 above the average size, but all the measurements recoi'ded fall 

 quite within the limits of individual variation reached hjA.j. 

 jamaicensis ; the specimen is matched, or surpassed, by a good 

 number of A. j. jamaicensis from many different places. The 

 measurement of the lower tooth-row must have been taken from 

 the front of the canine to the back of m^, not to the back 

 of my (or it would be greater than, not the game as, that of 

 the upper row, from c to m"). The measurement of the second 

 phalanx of the third digit, stated to be 40 mm., is obviously 

 wrong. The light colour of the fur is due to the specimen being, 

 as said by Allen, " very old." The absence of facial stripes is a 

 common feature in A . j. jamaicensis. — An example from St. Kitts 

 examined by me (U.S. IST. M. no. 110939) is in every respect 

 (external characters, skull, teeth) indistinguishable from A. j. 

 jamaicensis; it shows no approximation to A. j. jwceceps.

Diagnosis. — Similar to A. j. jamaicensis, but skull, teeth, and 

 external dimensions averaging somewhat larger. Total length 

 of skull, to front of canines, 28'8-30 mm. (average 29-7); zygo- 

 matic width 18*2-18'5 mm. (average 18"3); maxillary tooth-row 

 10-8-11-2 mm. (11-0); forearm 60-8-66 mm. (62-9).
