HARRIS: CRAYFISHES — GENUS CAMBARUS. 127 



30. NeAv Mexico. 



1. Abundant in the Gallinas river at Las Vegas and in the neighboring waters 



[San Miguel county]. (Cockerell and Porter, '00.) 



2. In lakes near Watrous [San Miguel county]. (Cockerell and Porter, '00.) 



3. In irrigating canal at Roswell, Chaves county. (Cockerell and Porter, '00.) 



42. Texas. 



1. [Trinity R.], Dallas [Dallas county]. (F. '85.) 



2. [Canadian or Red R ], east of Canadian river. (F., '85.) 



Faxon ('84 and '85) reports this species in pools vpest of the hundredth merid- 

 ian, east of the Canadian river, probably vpithin the limits of Texas. 



According to Cockerell ('00) , and Cockerell and Porter ('00) , 

 C. gallinus is abundant in the Gallinas river, at Las Vegas, and 

 in neighboring waters ; also found in lakes near Watrous, N. M., 

 and at Roswell. 



The material arranged preliminary to C. gallinus by Harris 

 ('00 and '02) was taken in a narrow strip of territory running 

 north for about eighty miles from the southern boundary of 

 Kansas and drained by the Arkansas river. Two small speci- 

 mens, each slightly over an inch in length, were taken in a 

 little running stream (Harris, '00). Material was taken in a 

 slough near Halstead, Harvey county (Harris, '00), which con- 

 nected in wet weather with a creek not a mile away. In July 

 of 1900, when a part of the material was taken, the water was 

 running more than usual, on account of recent rains, and no 

 burrows were observed. About November 10, when the locality 

 was again visited, specimens were taken from burrows. One 

 of these, about one foot deep, had its mouth below the surface 

 of the water. The others were along the bank, close to the 

 water's edge. " Chimneys" were not very conspicuous. The 

 burrows themselves, so far as noticed, were unbranched, about 

 three inches in diameter, and extending almost straight down 

 for a distance not to exceed one and one-half feet. One animal 

 was found in each burrow. 



A small slough four miles west of Caldwell, Sumner county 

 (Harris, '02), had been dry all of the summer of 1901, owing 

 to the very severe drought, but a spring a little distance from 

 the edge still contained a small pool of water, perhaps three 

 feet in diameter, although the water had ceased to flow into the 

 slough. In the small pool were noticed a number of small 

 specimens, about one inch in length, and, while none were 

 taken, they undoubtedly belonged to the same species as the
