4 THE NAUTILUS. 



species available for food supply, and therefore of commerical 

 importance. Nor have I mentioned species that are "occasionally 

 thrown into clam-bakes," or others that " were formerly eaten by the 

 ^ ^ :K Indians." A comparison in harmony with Mr. Keep's paper 

 requires a list of those species of mollusks that are ordinarilj' on 

 sale in the markets of Providence and Newport, and this is what 

 Mr. Carpenter should have given. 



The space occupied by this criticism, etc., is perhaps out of pro- 

 portion to the importance of the matter criticised ; so I will only 

 take up the stitch previously dropped and in closing express my 

 surprise and astonishment at the effect of Rhode Island "scallop- 

 rims," on Pawtuxet and East Greenwich cats, tabbies or tommies, 

 not specified, and marvel greatly over the possibility of turning 

 mules into horses by the same kind of fodder. 



Another and more serious matter is hinted at, for the mollusks of 

 California, Maine and Rhode Island are referred to as "regulars" 

 and " irregulars." This has the flavor of war. I have never seen 

 any military clams on the West Coast. I presume the " regulars " 

 belong to the standing army, and the " irregulars," are to be 

 regarded as militia only.

A recent discussion of this genus in the pages of the valuable 

 English magazine, Annals and Magazine of Natural History, is proba- 

 bly of sufficient interest to American conchologists to justify us in 

 reprinting the several articles.

While working on the slugs at the British Museum I came across the type spec- 

 imens of Li/nacella Inctiformis, Blainville. The two examples are in a bottle with 

 the label "Limacella lactesiens,^' and another label, apparently written by Dr. 

 Heyneniann, "Original zu Fig. 1, Taf. 7. Fer. Hist. Nat." They are true
