Teeth. — Similar to maclcayii but for the following exceptions : median 

 upper incisors very broad and very distinctly bilobate ; first upper pre- 

 molar small and low, considerably crowded; second lower premolar 

 shorter and broader, the basal outline more rounded and not so oblong 

 as in macleayii.

 head 17.3; ear 12.5; tragus 4.S; forearm 38.5; thumb 7; third digit 

 63.5; tibia 16.5; calcaneum 18; foot 8.5; tail 18. Average of series:

 [2] 16.9 (16.5-17.3); ear [2] 12.2 (12-12.5); tragus [2] 4.5 (4.3-4.8) 

 forearm [6] 38.7 (38-40); thumb [2] 7; third digit [2] 62.2 (61-63.5) 

 tibia [5] 15.6 (15-16.5) ; calcaneum [2] 19.7 (18-20.5) ; foot [6] 8.4 (8-9)

Type skull: Total length 15.3 mm.; interorbital width 3.5; height 

 at base of second premolar 3.5 ; height of brain-case 6.4 ; width of pala- 

 tal constriction 1.5; length of palate 6; width of palate including teeth 

 5.5; greatest length of mandible 11. Average of series of skulls : Total 

 length [5] 14.8 (14.2-15.3); greatest zygomatic width [3] 8 (7.9-8); 

 interorbital width [5] 3.2 (3-3.5) ; height at base of second premolar [5]

 striction [5] 1.4 (1.3-1.5); length of palate from anterior foramina [5] 

 6.1 (6-6.4) ; width of palate including teeth [5] 5.3 (5.1-5.5) ; length of 

 mandible [5] 10.8 (10.6-11.1). 



Remarks. — The foregoing description presents the differential char- 

 acters of inflata so that no general remarks are necessary. The phyla 

 represented by m. fuliginosa and m. infiata reaches its extreme type in 

 the latter race, the most apparent diagnostic character of which is the 

 inflated rostrum. 



Specimens Examined. — Two alcoholics and four skins : 



Cueva di Fari, near Pueblo Viejo, Porto Rico. (A. N. S. P. and 

 U. S. N. M.) [5.] 



Mayaguez, Porto Rico. (U. S. N. M.) [1.]
