Mr. J. L. Wortnian, who had charge of a scientific party last year, informs hh- that 

 while lishing one day he caught numbers of chub (Cj/prinida') and, throwing them 

 on the sand, was suri>rised to see that bnt few remained. While quietly continuing 

 to rcplact^ tliose so singularly missing, he observed a garter snake seize and swallow 

 one of the fish ti inches in length. There were two of these snakes reaping the 

 reward of Mr. Wortman's skill. Upon opening the snakes one was fonnd to contain 

 six lishcis. Tile head waters of the Smoky Hill and Big Horn rivers abound in this 

 aquatic i'lita tiia radix.

Scales ill twenty-one rows, all keeled except inferior row, which some- 

 times i)reseiits short keels at the bases of the scales. Superior labials 

 eight, eye over fourth and fifth. Three postoculars. Temporals 1-2. 

 L.iteral band on the third and fourth rows of scales. Dorsal baiul want 

 iiift' or only distinct on the renioval of the epidermis. Sometimes the 

 dorsal region yellower than the sides for a width of from four to six 

 scales. A low of black spots above the lateral stripe, which are some- 

 times divided so as to form two rows, one above the other. A row of 

 incomplete black spots below the lateral line, which are formed by the 

 adjacent black edges of three or four scales. A black spot ou each 

 side behind the angle of the mouth, whi(;h extends upward to near the 

 occii)ital shields and is ])receded by a light s])ot of half crescentic form. 

 The last sui)erior labial aud temi)orals in front of this space have black 

 edges. Superior labials slightly black-edged. Gastrosteges, one

There are two well marked subspecies of the U. macrostennixi, which 

 differ as follows: 



Larger and darker cohn-ed, spots and bands indistinct, ])aired si)ots nn parietal i>lates 

 generally absent A', m. viacrontcmma Kennicott. 



Smaller and brighter colored; ground, strijies, labials, and belly yellow; labials 

 black-bordered; i)arietal spots present JJ. m. Jlarilabris Cope.

This species has been found in Arizomi, whence two si)ecimens were 

 sent to the Zoological (iarden at Pliiladcl[)liia. They are of plain 

 brownish colors, and resemble at first sight the JJ. sirtalis sirtalis.
