is very much broader, and the form of the malar bone very diff- 

 erent. Both species somewhat resemble L. aquaticus externally, 

 but are readily separable from it and from each other by the 

 cranial characters.

In 1877 a single specimen of Lepus from Mirador was referred 

 by me (1. c.) to Lepus palustris. This was the only specimen 

 thus referred, or then known to me, from any point outside of 

 South Carolina and Georgia. Florida has since been added to 

 its known range, but it has not yet been found at any point in the 

 Gulf States west of Florida, where considerable collecting has 

 since been done. Hence the single record from so remote a 

 point as Mirador, Mexico, has of late seemed open to serious 

 question. I am hence much gratified to be able to revise the 

 record by a reexamination of the Mirador specimen. It is in 

 poor condition, but is still 'available for study. The skull having 

 just now been removed by my request, it proves to represent a 

 very distinct type of the genus, so far as cranial characters are 

 concerned. Externally it so much resembles L. palustris, that on 

 seeing it again after a long interval the question arose as to 

 whether its alleged Mirador origin might not have resulted from 

 a transposition of labels. As soon, however, as the skull became 

 available it was evident that the resemblance of the Mirador 

 specimen to L. palustris was wholly superficial, and limited to 

 external characters. It differs, however, somewhat from L. pal- 

 ustris in coloration, as stated in my former reference to it, as fol- 

 lows : " By far the most highly-colored specimens is one from 

 Mirador (near Vera Cruz), Mexico, in which the black is consid- 

 erably more prevalent than in average specimens from the Atlantic 

 States. The grayish area below is also more restricted and more 

 suffused with brownish." Mr. Alston quotes this (1. c.), and adds : 

 " The same remarks apply to an example contained in Mr. Salvin's 

 Guatemalan collections in the British Museum," the specimen 

 here referred to being the one mentioned by Tomes (1. c.), from
