Mr. W. Clark on some of the Animals of the Chemnitzise. 209 



Chemnitzia rufa, auct. ; Annals, N. S. vol. vi. p. 457, & vol. vii. 

 p. 386. 



Chemnitzia formosa, nonnuU. ; and Annals, N. S. vol. vii. p. 387. 



I have seen several large specimens in the present month, June 

 1852; the only correction I offer is for, "The head or muzzle 

 proceeds from the coalescing tentacular membrane, forming a 

 sort of head-veil a little beyond the foot,^' read '^ the rostrum, is 

 long, flat,'' &c. &c. 



Chemnitzia fulvocinctay Annals, N. S. vol. vii. p. 387. 

 The above reference explains all I know of this species, which, 

 with most authors, is a synonym of Ch. rufa, 



Chemnitzia spiralis, Mont. ; Annals, N. S. vol. vi. p. 457. 



Odostomia spiralis, nonnuU. 

 I have no additional observations to make on this species. 



Chemnitzia Sandvicensis, Walker, Test. min. rar. ; Annals, N. S. 

 vol. vii. p. 388, and vol. viii. p. 110. 



Odostomia dolioliformisy nonnuU. 

 I have nothing more to offer on this species. 



Chemnitzia decussata, Mont.; Annals, N. S. vol. viii. p. 111. 

 Odostomia decussata, nonnuU. 



Chemnitzia elegantissima, Mont. ; Annals, N. S. vol. viii. p. 112 ; 

 Brit. MoU. 

 I request that the following sentence may be added to the de- 

 scriptive matter : — The Ch. degantissima is never marked with 

 purple streaks as in Ch. pusilla, and the tentacula are carried 

 more in a line with the body than in that species ; the shell is 

 also more taper and of a more opake sordid texture, but recent 

 examples must be compared to see the value of this distinction. 



Chemnitzia pusilla, Philippi; Annals, N. S. vol. viii. p. 113. 



The addendum to the preceding species will apply to this ; I 

 have only to observe, that the constant variations in colour, con- 

 tour, and texture of the shells have been verified by the exami- 

 nation of near twenty live individuals of this species. 



Chemnitzia Gulsona, Annals, N. S. vol. vi. p. 459, and vol. viii. 

 p. 108. 



1 have searched in vain for a second example of this rare ani- 

 mal ; 1 am anxious to review it ; however, I do not despair of again 

 meeting with it.
