Two specimens (A. M. N. H. No. 5646 and U. S. N. M. No. 64587) 

 of this species were collected by the Albatross Expedition at Miraflores. 



One typical pale specimen, U. S. N. M. No. 37566, comes from the 

 Cocopah Mountains, east base, collected by the Biological Survey Ex- 

 pedition. 



Crotalus goldmani, 1 new species 



Diagnostic Characters. — Allied to Crotalus mitchellii by the separation of the 

 rostral and nasal plates by a row of scales; distinguished by: (1) dark reddish brown 

 coloration, with the dark markings more nearly rhombic, and with light centers; (2) 

 scales narrower and more convex; (3) supraocular plate broken up into three or four 

 small scales. 



Range. — Known only from the type locality. 



Type.— U. S. N. M. No. 37573, &; El Pirion, Lower California, 5300 feet; July 

 9, 1905; E. W. Nelson and A. E. Goldman. 



Description of Type. — Habitus apparently stout, tail short, muzzle short; 

 scales of top of head small, somewhat convex; canthus rostralis obtuse; rostral 

 slightly higher than wide; a single row of scales between rostral and nasal; two pre- 

 oculars, with two loreals between them and the posterior nasal, on each side; upper 

 labials, 18-19; lower labials, 16-17; a small triangular area of small scales (8 or 9) 

 between the loreal pit, the nasals, and the labials; supraocular divided into four scales 

 on one side, three on the other, but with the fourth indicated; scales rather convex, 

 especially on the head and tail, only the first row smooth; ventral plates, 180; sub- 

 caudals, 25; dorsal scales, 23-27-21. 



Total length, 850 mm. ; tail-length to base of rattle, 70 mm. 



General color brownish; ventrals with irregular brown punctation; back with 

 rhombic markings of darker brown, as long as wide; on the anterior part of the body 

 they are notched on the mid-line; posteriorly they become wider and narrower, with 

 seven dark bands on the top of the tail, the last three nearly black. 



In view of the known variability in the scutellation of C. mitchellii, 

 the present specimen may prove to be merely an abnormal one of that 

 species. C. mitchellii, however, has not previously been recorded from 

 the Pacific slope of the San Pedro Martir Mountains. It is typically a 

 desert species, although it ranges into the lower border of the upper 

 Sonoran life zone in California (4500 feet, at Asbestos Spring, east slope 

 of the San Jacinto Mountains). The conditions described at El Pirion 

 by Nelson (1921, p. 20) indicate thoroughly non-arid habitat conditions. 



•Named for Mr. A. E. Goldman, Bureau of Biological Survey, associated with Dr. E. W. Nelson in 

 the Lower Californian explorations of the Bureau of Biological Survey.
