the fossil beds on the Central R. R., 46 kilometers from Natal, below 

 the station of Taipu, half a dozen were taken at Estremoz and a 

 single dead specimen, taken at Camocim, was sent from the Goeldi 

 Museum. It differs from the type in its more slender shape and 

 slightly smaller size. 



The whorls are 7j, alt. 23, diam. 12 mm. 

 Bulimulus (Rhinus) roohai suturalis n. subsp. PI. XXIII, figs. 13, 14. 



This is a fairly well-marked variety, differing from the type by 

 being thinner, smaller in size, slightly more globose, with fewer 

 whorls, never more than six, the spire being distinctly chestnut 

 colored with an extension showing in a light bron-n band on the 

 lower curve of the suture. 



Alt. 17, diam. 12. 



Ten living specimens were taken at Mongiiba, a station on the 

 Ceara & Baturite R. R. about 27 kilometers from Ceara, and eleven 

 specimens sent by Mr. Rocha ''from the State of Ceara" correspond in 

 shape with this variety, but lack the sutural band."

 DrymcBus expansus Pfr., Pilsbry, Man. Conch. (2), XI, p. 222, pi. 34, figs. 1-5. 



A single, half -grown specimen taken at Camp 46. M. & M. R. R., 

 seems to be referable to this species. 

 Drymaeus branneri n. sp. PI. XXIII, figs. 1, 2, 3, 4. 



Shell broadly and openly rimate, ovate conic, thin, diaphanous, 

 shining, white or light Jjrown, typically marked in chestnut by a 

 narrow band beginning within the mouth just below the upper lip 

 attachment and continuing around the last whorl, below the pe- 

 riphery, to a point about three millimeters behind the flare of the lip, 

 and two interrupted bands, above and parallel to this, disappearing 

 before reaching the penultimate whorl, the tendency being in most 

 shells to a lessened development of these markings; embryonic 1| 

 whorls with typical Drymaeus sculpture, the remaining portion of 

 the shell being everywhere sculptured with irregular, retractive 

 costulae cut by close, finely incis,ed, wavy lines, subobsolete on the 

 earlier whorls; spire conic, with slightly convex outlines; apex 

 obtuse. Whorls 5| to 5f , slightly convex, the last well rounded, very 

 convex below, slightly ascending in front. Aperture short oval, 

 very slightly oblique, showing the external markings within; peris-
