oblique, coiistanily with six teeth, of which two are on the trans- 

 verse lip, the inner one being a little larger; two teeth are on the 

 columella, the upper one being a little larger; and on the outer 

 side are two, of which the lower one is a little larger ; umbilicus 

 very small. This species resembles P. ovata Say. See the excel- 

 lent monograph by Dr. Gould of the Pupae of the United States in 

 the Bost. Journ. Nat. Hist. Vols. III. and IV. 



Length .0S5 inch ; breadth ,055 inch. 



Pupa exilis. Shell tapering and much elongated ; white ; 

 smooth ; spire slender, with scarcely convex outlines ; apex obtuse ; 

 whorls nearly six, rather convex, with a well impressed suture ; 

 aperture oblique, long, contracted at both extremities, rather angu- 

 lar anteriorly; lip well reflected and thickened ; on the left side of 

 the aperture is a strong transverse tooth, and there is a smaller ob- 

 lique tooth at the end of the columella ; umbilicus very small. 

 This species much resembles P. exigua Say, but tapers regularly 

 from the middle of the last whorl, and is more slender. 



Length .08 inch ; greatest breadth .028 ipch ; least breadth .025 

 inch. 



SucciNEA LATioR. Shell obliquely elliptical ; pale amber color ; 

 extremely thin, with rather coarse unequal striae of growth ; spire 

 small ; apex acute; whorls three and one-third ; quite convex, with 

 a well impressed suture ; aperture oval, acutely angular above, not 

 oblique. This species is intermediate, in the form of the last whorl 

 and in its proportion to the spire, between S. campcstris Say, and 

 S. ohliqua Say, but is much thinner than either of those species. 

 S. Sagra (?) Orb., the allied species of Jamaica, is narrower and 

 smoother. 



Length .53 inch ; breadth .34 inch ; length of aperture .43 inch ; 

 breadth .27 inch. Of another individual, length .43 inch; breadth 

 .27 inch. 



SucciNEA ANGUSTioR. Shell very long ovate ; brownish horn 

 colored ; well covered with striae of growth, not shining ; spire 

 long ; apex acute ; whorls three and one-half, long, rather convex, 

 with a well impressed suture ; aperture oval, rather small, not ob- 

 lique. A large specimen is .3 inch long and .16 inch broad ; 

 Jength of aperture .2 inch; breadth .12 inch.
