has never been found farther south than San Diego, and its true 

 habitat is probably on one of the islands of the coast, while our 

 species is essentially a Lower Californian, being found under 

 stumps of Maguey from Sto. Tomas to a little beyond Rosario. 



Helix Lohrii, Gabb. — Plate 16, fig. 2. 



Description. — Shell discoidal, flattened above, resembling in 

 form //. sepidchralis of Ferussac, apex very flat, or in some spe- 

 cimens slightly elevated ; whorls four to four and a half ; flat- 

 tened on the upper side, rounded or slightly subangulated above 

 and sloping inwards underneath ; suture impressed ; body whorl 

 sloping a little on the upper side towards the mouth ; aperture 

 broad, oblifjue, and bordered by a rather heavy and pretty 

 strongly reflected lip not continuous on the inner side, except by 

 an almost imperceptible coating on the body whorl ; umbilicus 

 broad, showing all of the whorls. Surface showing, under a 

 glass, besides the ordinary lines of growth, minute puactations, 

 as if the live shell were hirsute ; color (all the specimens dead) 

 whitish, Avith a revolving brown band on the margin of the upper 

 side. 



Observations. — This shell diff"ers from sepidchralis in its apex 

 being less elevated, and the umbilicus being more open ; from 

 Mcwellii, Newc, it can be distinguished by being less elevated, 

 having the mouth more elongated laterally and the lip more ex- 

 panded. It is a large species. 



Locality. — From the higher table lands near Moleje. All of 

 the specimens found were dead. 



H. Remondi, Tryon. 



Dead specimens of this species were not rare in the mountains, 

 associated with the preceding, and I was fortunate enough to 

 find a living one at Trinidad, on the west coast, near San Borja, 

 north of the range of Lohrii. It overlaps the habitat of that 

 species, and extends farther north, but always in the mountains. 

 It is not improbable that the species given us by Mr. llemond 

 may have been carried from Moleje to the opposite port of 

 Guaymas, where he obtained them. 



The shell is a beautiful translucent horn color, with a strongly 

 marked, dark brown band. The animal is dark grey above, 

 shading into a delicate yellowish-brown on the margin of the 

 foot.

 spire high ; whorls seven, rounded ; suture slightly impressed ;
