 J. C. Warren, M. D., President, in the Chair. 



Mr. Alger read remarks on a Mineral specimen, which he 

 exhibited, and had lately received from Dr. Feuchtwanger 

 as a new species. 



Mr. Alger suspected, from its gem-like appearance, hardness, 

 and weight, that it might be allied to the Sapphire class ; and on 

 further examination, pronounced it a splendid red Sapphire, or 

 Corundum. It is from Cherokee County, Georgia. Mr. Alger's 

 paper will be published in the Journal. 



Dr. Gould gave descriptions of the following species of 

 Shells from the collection of the Exploring Expedition. 



Bulla parallela. Testa parva, tenuis, cylindracea, lactea, 

 antice rotundata, postice conica, imperforata, longitudinaliter 

 minutissime striata, ad verticem et ad basim striis undulatis de- 

 cussata : apertura angusta, deorsum dilatata ; columella callo 

 haud appresso induta ; labro ultra spiram adscendente, tunc de- 

 orsum intorta. Long. ^^^, lat. ^ poll. Hah. 



Much smaller and thinner than B. solidula, though striated at 

 the ends like h, and having the same conformation of the lip. Its 

 sides also are parallel and not bulging. 



Tornatella bullata. Testa parva, ovata, tenuis, albida, 

 epidermide stramineo fugacissimo induta, spiraliter sulcata, sulcis 

 linearibus ad 5 ordinatim dispositis in singulis anfractibus : spira 

 prominula, turrita ; anfr. 5 tabulatis, ultimo magno, ventricoso, 

 15-sulcato, supernis planulatis ; sutura canaliculata : apertura 

 semilunaris ; columella uniplicata, planulata. Long. J-, lat. -^ 

 poll. Dredged off Patagonia. 



This little species, like T. puncto- striata and T. veniista, to 

 which it is allied, has not the ivory surface of most species. It 

 is well characterized by its form and sculpture. 



Haliotis crispata. Testa parva, tenuis, convexa, elongato- 

 ovalis, undulis obliquis angulatis divaricantibus rugata, spiraliter 

 striata, rubida : spira elevata, sub-mediana ; foraminibus parvis,
