D. SUBEFFUSUS (Philippi). PL 48, figs. 43, 44. 



Shell perforate, fusiform-turrited, rather thin, striatulate ; whitish, 

 ornamented with brown longitudinal lines. Spire conic, lengthened, 

 rather acute. Whorls 7, a little convex, the last about three-fourths 

 as long as the spire. Columella somewhat folded, then bent to the 

 right; aperture ovate-oblong, angulate at base; peristome rather 

 thin, the right margin narrowly expanded, columellar margin dila- 

 ted, hardly covering the perforation. Alt. 40J, diam. 17 mill. ; 

 aperture 19 mill, long, 9 wide. (Phil.^).

Bulimus subeffusus PHIL., Malak. Bl., xvi, 1869, p. 36. PFR.,

Based by Philippi upon a single somewhat faded specimen, which 

 in form of the shell and expansion of the lip resembled B. zoograph- 

 ieus Orb. ; but the aperture is subangular at base, the lower part of 

 the columella bent to the right, as in B. hamadryas Phil., and the 

 color pattern is like that of B. linostoma Orb. 



D. PEALIANUS (Lea). PL 41, fig. 26. 



Shell ovately conical, imperforate, smooth, shining, ash-colored, 

 rather thick, furnished with longitudinal purple spots ; whorls 6. 

 Aperture widened out, purple ; outer lip acute, reflected. Length 

 I'l, diam. 0'4 inch. (Lea). 



Near the Rapids of Angostura, Colombia (T. R. Peale). 



Bulimus pealianus LEA, Trans. Amer. Philos. Soc., vi, p. 65, pi. 

 33, f. 105 (1838) ; Observations on the genus Unio, etc., ii, p. 65, 

 pi. 23, f. 105. 



During Mr. Peale's travels in Colombia he found a single speci- 

 men of this beautiful species, and I am indebted to his kindness 

 for the privilege of describing it. In this individual the longitudi- 

 nal spots are more numerous on the whorl next to the body whorl, 

 there being none on that part near to the outer lip. (Lea}. 



The type of this species was placed by Peale in his Philadelphia 

 Museum. It -was lost either in the fire which destroyed a large por- 

 tion of that collection, or at the final dispersal of the remainder. 



The species is unknown in American collections. Pfeiffer has
