CHARINA Circy. 

 Cat. Sn. Br. Mus., 113 (1849); Cope, I. c, 592 ; Boul., I. c, I, 130. 



Anterior teeth longest ; head covered with shields ; a frontal 

 plate ; two nasals, eye small with vertical pupil ; tail short, not 

 pi'ehensile; subcaudals undivided, 



Hab. — Western coast of North America. 



Charina bottae Blainville. 



Tortrix bottce Blain., Nouv. Ann., 1834, 57, PI. XXVI, fig. 1; Wenona 

 plumbea and isahella B. and G., I. c, 139, 140 ; Charina botke Cope, 

 I. c, 592, and Eep. Nat. Mus., 728 ; C. botUp. Boiil., I. c, I, 130. 



Body short and stout; rostral prominent; two nasals, the 

 anterior frequently fused with the internasals; loreal sometimes 

 fused with prefrontals; head plates variable ; upper labials 8-11; 

 scales smooth in 37-49 rows; ventrals 192-211; anal entire; sub- 

 caudals 20-37, mostly entire. Total length about 550 mm. (tail 

 50). Grayish to brownish above, yellow beneath. 



In the present genus Mr. Stejneger has again demonstrated the 

 worihlessness of characters drawn from the scales,'' although he 

 prefers to provisionally retain jylumbea B. and G. The difference 

 of four rows of scales between the type of bottce and the minimum 

 of plumbea is much less than the normal range of variability in 

 almost every known species of BokUe. 



Hab. — Oregon to Lower California and Nevada. 



Charina brachyops Cope. 



Proc. U. S. Nat. Mus., 1888, 88 ; I. c, 592, and Eep. Nat. Mus., 727 ; 

 Boul., I. c, I, 131. 



One specimen only is known of this species. It differs from 

 bottce in that the posterior prefrontal forms a part of the orbit, 

 and the loreal is absent, leaving the postnasal in contact with the 

 preocular. The constancy of these characters is not known, and 

 the form is retained provisionally. 



Hab. — Point Reyes, California.
