52 THE LITTLE SHELLS. 



Chemnitzia castanca^ Cpr., cas-tan'-e-a, is repre- 

 sented in Fig. 33. The shell is somewhat 

 larger than that of the last, and is of a chestnut 

 color, as the name indicates. Its eight or ten 

 whorls are marked with numerous fine ribs, 

 and though so small, it is a beautiful shell. 

 Fig. 33- Cheinnitzia tenuiciila^ Gld., ten-u-ic^-u-la, 

 is another representative of the genus which was 

 named for the scholarly Chemnitz. It is a southern 

 species, has flattened whorls, and is marked with fine 

 and crowded ribs. Color, brownish ; length, one- 

 fourth of an inch. 



Dunkeria laminata^ Cpr., Dun-ker'-i-a lam-in-a'-ta, 

 is the name of another similar mollusk belonging to 

 a sub-genus of Chemnitzia. 



Its shell is similar in size and color to that of the 

 last species, but its eight whorls are more rounded 

 and more finely cancellated. 



Oscilla iiisciilpta^ Cpr., Os-siF-la in-skulp'-ta, is very 

 minute and has a spire-shaped shell, the five whorls 

 of which are marked by a few strong spiral ridges. 

 Whitish ; length, one-eighth of an inch. 



Miralda qiiinqtiecincta^ Cpr., Mi-ral'-da quin-que- 

 sink'-ta. Five-banded Miralda. The little shell is of 

 the same size and color as the last. The sutures are 

 distinct, and the flat whorls are marked by a few 

 strong spiral bands and many minute cross-ribs. 



The list of these graceful but inconspicuous crea- 

 tures is not yet complete, for, closely following, we 

 have Evalea te^iitiscidpta^ Cpr., K-va'-le-a ten-u-i- 

 sculp'-ta, with its white, few-whorled, nearly smooth 

 shell, a little over one-eighth of an inch long ; and 

 its sister, Evalea graciliente^ Cpr., gra-sil-i-en'-te.
