My cabinet and cabinet of Mr. Moores. 

 Diam. -24, Length -39 inch. 



Remarhs. — I am indebted to Mr. Moores for five sj)ecimens of this species, and I 

 name it after him. At first I thought it might belong to luteola, Gould, or lineata, W. 

 G. Binney. But it is more globose than the former, has one whorl less, and is devoid 

 of any yellowness in the interior which so well marks that species. From lineata it 

 differs in being without the " revolving lines which distinguish it," as well also in the 

 form of the aperture as described. It is, however, more like the figure given by Mr. 

 Binney, which disagrees with the description, as that descxnbes the aperture to be 

 half the length of the shell, while the figure represents it as two-thirds the length. 

 Mooresiana need not be confounded with campestris, Say, that species being more 

 globose, thicker and rougher on the exterior. The aperture is about five-eighths the 

 length of the shell.

My cabinet and cabinet of Dr. Hale. 

 Diam. -17, Length '23 inch. 



Remarks. — This is a pretty little golden-colored species, of which Dr. Hale sent to 

 me about a dozen specimens ; and I have great pleasure in naming it after him. It 

 is allied on one side to Oregonensis, (nobis,) and on the other to aurea, (nobis). It 

 differs from the former in being smooth and shining and having a less exserted spire ; 

 from the latter in being rather smaller, being less bright, being rather darker, and 

 less pronounced apicial whorls. The aperture is about two-thirds the length of the 

 shell. 



Since I published in 1841 a number of new species of Succinea, Dr. Binney's 

 Terrestrial Shells of the United States has appeared. In Vol. II. pages 65 and 66, 

 he gives eight of my species with the Latin diagnosis, and says he had seen Wardi- 

 ana, Totteniana, Nuttalania and aurea, but had no knowledge of the others except 

 what he derived from descriptions and figures ; and further, that " on a careful
