4 DESCRIPTION OF 
Remarks.—This species was sent to me by the late Dr. Ward from Roscoe, in the north- 
ern part of Ohio, and I presume came from the vicinity of that place. It is allied to SS. 
vermeta, (Say,) but has a less exserted spire and is not quite so oblique. It is also a smaller 
species. ‘The aperture is about two-thirds the length of the shell. 
SuccinEa TOTTENIANA. 
Testé obliquo-ovatd, subnitidd, subdiaphand, obsolete striatd, corned; spird brevi; suturis impressis; anfractibus 
ternis, convexis; apertura ellipticd. 
Shell obliquely ovate, somewhat shining, rather transparent, obsoletely striate, horn colour; spire short; sutures im- 
pressed; whorls three, convex; aperture elliptical. 
Hab. Newport, Rhode Island. Col. Totten, United States Army. My Cabinet, and Cabinets of 
Col, Totten, and P. H. Nicklin. Diam. .30, Length .48 of an inch. 
Remarks.—Many years since Col. Totten sent me this species. Never having been able 
to identify it with any described species, I now propose to name it after him. It is rather 
an inflated species, but not so much so as the obliqua, (Say,) nor is it solarge. It resembles 
the ovalis, (Say,) but is rather smaller, more oblique and less inflated. The aperture is 
rather more than two-thirds the length of the shell, and the apex is very small, somewhat 
mamillate. ‘The epidermis is rather dark. The substance of the shell is slightly iri- 
descent, giving it an opalescent appearance, and this is slightly observed through the 
epidermis. 
SuccineA NUTTALLIANA. 
Testa longo-ovatd, obliqua, subnitidd, diaphand, striatd, pallido-luted; spird subelevatd; suturis impressis; anfrac- 
tibus ternis, subconvexis; apertura longo-ovata. 
Shell long-ovate, oblique, transparent, striate, pale yellow; spire rather elevated; sutures impressed; whorls three, some- 
what convex; aperture long-ovate. 
Hab. Oregon. Prof. Nuttall. My Cabinet and Cabinets of Prof. Nuttall, and Dr. Jay. Diameter 
.25, Length .50 of an inch. 
Remarks.—A very oblique, slender and graceful species, allied to retusa nobis, but 
smaller, less elongated, and not having the inferior part or base quite so retuse. The 
aperture is about three-fourths the length of the shell. 
SUCCINEA AUREA. 
Testa obliquo-ovatd, nitidd, diaphand, levi, aured; spird subelevatd; suturis impressis; anfractibus ternis, convewis; 
apertura ovata. 
Shell obliquely ovate, shining, transparent, smooth, golden; spire rather elevated; sutures impressed; whorls three, con- 
vex; aperture ovate. 
Hab. Springfield, Ohio. T.G. Lea. My Cabinet and Cabinets of T. G, Lea, and P. H. Nicklin. 
Diam. .20, Length .32 of an inch. 
Remarks.—This is a beautiful little species, remarkable for its fine surface and bright 
golden colour. In form it is nearly allied to vermeta, (Say.) In colour it has some resem- 
blance to a species sent to me by M. D’Orbigny, from Paris, under the name of putyis, 
Lin., and obtained by him in Colombia. His shell is quite different from the putris of 
Europe, and I propose the name of the distinguished traveller for it; if I am correct, 
Succinea Dorbigniana. 'The aperture of the aurea is about three-fifths the length of the 
shell.
