General Notes. 167 



to the Cuban species Solenodon cubanus Peters. In only one way is it 

 at all peculiar its fore-claws are very long and sharp and obviously had 

 not been used in digging or scratching for insects for some time before its 

 death, at once suggesting its having been kept in confinement. 



The whole matter, therefore, of the continental record of Solenodon may 

 be disposed of for good in a few words. The specimen (No. 3223, Mus. 

 Comp. Zool.) is a perfectly characteristic example of the Cuban Solenodon ; 

 it was sent without comment or special data from the Isthmus of Darien 

 by a reliable naturalist, but it has certain appearances of having been kept 

 in confinement, and in all probability was brought alive from Cuba to 

 Darien, where Dr. Maack secured it either still living or soon after its death.

ON THE HABITS OF CAMBARUS UHLERI FAXON. 



Gnnbarus uhleri, described by Faxon from a rather extensive series of 

 specimens sent him by Dr. Philip Uhler, is apparently confined to the 

 portion of Maryland known popularly as the Eastern Shore. According 

 to Dr. Uhler and his collector, his specimens were found in ditches, even 

 in places where the water was decidedly brackish. 



Two years ago in Somerset County, and last summer in Dorchester 

 County, I found the species rather abundant in burrows in low-lying 

 areas not far from the bay but always near ponds or ditches of fresh water. 

 In nearly every case the area selected was in dense pine woods. 



The burrows were quite similar to those made by C. dtogenes, and, like 

 that species, C. uhleri erects a chimney over the mouth of its burrow. The 

 chimney is usually rather low and can not represent any considerable por 

 tion of the earth removed from the hole, for in some cases this extended to 

 a depth of 4 or 5 feet. A single individual invariably occupied a burrow 

 and no communication between burrows was observed. In a lot of about 

 a dozen specimens collected near Crisfield, in September, 1903, both forms 

 of the male are represented ; it would therefore appear that the time of 

 ecdysis and transition from form II to form I must be in the late fall. 

 From inquiries I learned that in the spring the animals emerge from their 

 burrows and are common in ditches and small streams. This emergence, 

 like that of C. dioyenes, is doubtless for the purpose of mating, which having 

 been accomplished, the crayfish returns to a burrow or digs a new one. 

 The color of all the specimens observed was a dirty greenish brown, the 

 tips of the chelae alone being somewhat reddish. Dr. Uhler, in conversa 

 tion, has reported that some of his specimens were beautifully marked with 

 spots of golden yellow. Throughout the region mentioned the crayfish is 

 known as the " lobiftar" 



C. uhleri is unquestionably an offshoot from the C. diogenes stock and has 

 probably reached its rather isolated range from the north. The examina 

 tion of an extensive' series of specimens from localities lying farther to the 

 northward, but still on the Maryland-Virginia Peninsula, would be of 

 great interest and would doubtless throw some light on the post-glacial 

 distribution of our crayfishes. W. P. Hay.
