Capt. Robinson found these rabbits plentiful on the island in 1895 and 

 mentions (Proc. U. S. Nat. Mus., XXIX, p. 162, 1901) that they were 

 "split and dried like cod fish and brought by the boat load to La Guaira 

 for sale". But two individuals were noted near El Valle by Mr. Clark, 

 who states that the natives were in constant pursuit of them.

The single specimen from which this species was described was col 

 lected on the island by Capt. Robinson, July 8, 1895. The second known 

 specimen was captured at El Valle, late in July, 1901, by Mr. J. R. 

 Johnston, of Mr. Clark's party. He swept it into an insect net, think 

 ing it was a large moth, as it flew past in the early morning twilight. 

 Mr. Gerrit S. Miller, Jr., who has examined this specimen, writes that 

 it fully bears out the characters of the type as given in the original de 

 scription. The measurements taken from the specimen before skinning 

 and after an. immersion of several months in formalin, are: length, 66.5 

 mm.; tail, 31 mm.; ear, 11.5 mm.; forearm, 25 mm.; tibia, 11.4 mm. 

 The specimen is now in the collection of the United States National 

 Museum. 



9. Peropteryx sp. Sac- winged Bat. 



A single, much shattered specimen was obtained by Mr. Clark. It 

 was a female and was shot in a large cave on the hill southwest of 

 El Valle, July 13, 1901. It is quite possible that it represents an unde- 

 scribed species, but more and better material is necessary to decide this 

 point. It is intermediate in size between P. canina and P. trinitatis, the 

 tibia, in the dried specimen skinned out from formalin, measuring 17 

 mm., and the forearm 40 mm. The skull is slightly smaller than that 

 of P. canina though slightly heavier than that of P. trinitatis. The muz 

 zle is short and broad as compared with that of P. trinitatis and slightly
