48 bulletin: museum of comparative zoology. 



Remarks. — I cannot find that the Central American paca has ever been 

 named. The Museum has a large series of skulls of true A. paca from Brazil, 

 and several specimens, skins and skulls, of the northern form from Costa Eica, 

 collected by Gabb. One adult 9 taken by Mr. Brown, at Santa Marta, Col- 

 ombia, and Venezuelan examples in the United States National Museum, 

 are apparently referable to true A. paca. I have not seen any specimens from 

 Panama, but all examples from Costa Rica and Chiriqui belong to a race that is 

 easily separable from true A. paca of Brazil. 



The paca is said to be variable in color everywhere, light and dark indi- 

 viduals occurring together, but in spite of this I think the northern form 

 averages much darker, richer brown. It certainly has the upper of the two 

 lateral white stripes much less broken up into spots, and all the white spots 

 much smaller. Besides these differences in color and pattern, the Cen- 

 tral American animal is larger, with longer hind feet, and has a much larger 

 skull, with narrower palate and flatter audital bullae. Skulls of the paca vary 

 a good deal individually in regard to the roughening of the upper surface. In 

 some old skulls the upper surface is excessively roughened, while in others of 

 about the same age it is comparatively smooth. 



Lepus (Tapeti) gabbi (Allen). 



Nine specimens, Divala, November and December. Boquete, 3,400 to 4,500 

 feet, March and April, and Bogaba, July. 



The seasonal differences in color are well shown by this series. July speci- 

 mens are much redder, with but few black-tipped hairs in the back, than 

 autumnal examples. 



Fells bangs! costaricensis Merriam. 



One female, Boquete, 4,000 feet, April 22, the type of Dr. Merriam's new 

 form. 



Felis pardalis Linn. 

 One fine adult ^, Boquete, 4,000 feet, April 10. 



Conepatus^ mapurito (Gml.). 



Two specimens, S and 9 adults, Boquete, 4,000 and 4,500 feet, February 

 and March. 



1 I am aware of the proposed change in the generic names of the skunks, but, 

 not having reached a definite decision, use the old name.
