Specim.eyis Examined. — Four specimens, two skins, two alcoholic 



individuals: Baracoa, Santiago, Cuba. (U. S. N. M.) 



Chilonycteris parnellii portoricensis (Miller). 



1902. Chilonycteris portoricensis Miller, Proc. Acad. Nat, Sci. Phila., 1902, 

 p. 400. [Cave near Pueblo Viejo, Porto Rico.] 



Type Locality. — Cueva di Fari, near Pueblo Viejo, Bayamon district, 

 Porto Rico. 



Distribution. — Known only from the type locality, but probably 

 found in suitable localities throughout the island. 



General Characters. — Similar to C. p. hoothi, but the size is less, 

 while the skull is somewhat inflated. 



Head. — Essentially as in C. p. hoothi, except that the ears appear to 

 be slightly smaller with the apical portion blunter and less falcate. 



Limbs. — Except for the slight difference in proportions, essentially 

 as in C. p. hoothi. 



Membranes and Fur. — As in C. p. hoothi. 



Color. — Above dark brown, between Ridgway's mars-brown and 

 bistre, pale on the nape where the ecru-drab under portion of the hair 

 is very evident ; below dark gray, the base of the hair on the abdomen 

 and chest seal-brown, on the throat and chin pale Isabella color; mem- 

 branes blackish-brown. The remarks made under C. p. hoothi concern- 

 ing color phases also apply to this form. One specimen shows a slight 

 approach toward the rufous form. 



t* Skull. — Similar to that of C. p. hoothi, except that the brain-case is 

 more arched transversely and the rostrum is distinctly broader and 

 heavier. This character is interesting, as it is paralleled by a similar 

 development in the Porto Rican form of the macleayii group. 



Teeth. — Essentially as in C. p. hoothi. 



Measurements. — Average of series: Total length [5] 77.3 (74-79); 

 length of head and body [5] 57.8 (54-66) ; length of head [4] 23 (21.5- 

 24.3) ; length of ear [4] 20.5 (19.7-22) ; length of tragus [4] 5.3 (5-5.7) ; 

 length of forearm [5] 50.7 (49.6-51.5) ; length of thumb [5] 8.2 (8-8.5) ; 

 length of third digit [5] 81 (79-82); length of tibia [5] 18.4 (18-19); 

 length of calcaneum [4] 22.9 (19-25) ; length of foot [5] 11.8 (10.5-12.5) ; 

 length of tail [4] 21 (19.5-23). 



Dimensions of one skull: Total length 20.5; greatest zygomatic 

 width 11.1; interorbital space 4; height at base of second premolar 

 4.8; height of brain-case 7.5; breadth of brain-case above roots of 

 zygomata 9.8; width of palatal constriction 1.4; length of palate from 

 anterior foramina 8.7; width of palate including teeth 7.5; greatest 

 length of mandible 15.6
