California Eegion, from Santa Cruz to Mendocino County. (Cooper.) 

 Tlie animal has a uniform dark lead-color over tbe body, darker on head 

 and eye-peduncles; base of foot dirty white. Tail almost carinated,poiuted. 

 The epiphragm is as usual in the genus. 

 Jaw as usual in the genus ; over ribs. 



Lingual membrane (Terr. Moll., Y, Tlate IX, Fig. F) as usual; teeth 

 44_1_44^ with IG laterals, the seventeenth tooth having its inner cut- 

 ting point bilid. 



The genitalia are figured on Plate XIII, Fig. C, of Terr. Moll., Y. 

 The ovary is yellow, long, narrow, concave on one side, convex and 

 carinated on the other. The accessory gland of th epididymis is com- 

 posed of long white Cfeca. The oviduct is extremely long, narrow, 

 convoluted. The genital bladder is globular, small, with an extremely 

 long duct, to which is added an accessory duct or branch almost as 

 long as the oviduct. This branch joins the duct near its end. It is 

 thicker than the duct. The duct enters the vagina at its upper part. 

 The penis sac is long, cylindrical, small, almost equaling in length 

 the oviduct and ovary united. The retractor muscle is inserted at 

 about the middle of its length; it is attached to the diaphragm. The 

 vas deferens enters about three-fourths of its length; beyond the 

 vas deferens is a tlagellate extension. The vagina is long and narrow; 

 near its base, o])posite the entrance of the sac of the penis, is a stout, 

 Fi,;. 1(1(5. cylindrical, long, hollow, vaginal prostate, gradually 



tapering at its apex, and extended into a delicate 

 tube, which soon becomes divided into two long 

 llagella. Just beyond the division, on each flagellum, 

 is a stout, bulb-like enlargement.

formerly described by me as H. anachorcta. It is here figured.
