Monograph of Cyprcea. 67 



Having had the opportunity of examining the cabinet of the unfortunate 

 but truly great Lamarck, at present in the possession of Prince Massena, I 

 observed that 



C. icterina, Lam., n., is the young of C. moneta; it is well figured in 

 this state by Petiver ; see Gaz. t. 97, f. 9. 



C. albella, Lam., n., is a small worn specimen of C. copwi serpentis. 



C. ursellus of Lamarck's cabinet consisted of worn specimens partly of 

 C. Hirundo and partly of C. felina. It is but just to remark that the 

 cabinet has been partially deranged by its being moved; and the 

 unfortunate blindness and feebleness of the original proprietor pre- 

 clude his re-examining it. 



M. Duclos in the Bulletin des Sciences Naturelles et de Geologic (vii. 

 385,) has given a list of the species which had been described in this 

 Monograph at that time, in which he has made the following remarks. 



" C. Arabicula. — M. de Lamarck en creantcette especea commisune 

 " erreur; I'individu auquel il a donne ce nom est un C. Arahica 

 " extremement petit, et a I'etat complet. M. Gray en commet une 

 '' plus grande encore en donnant ce nom a une variete du C. Turdus 

 '' ou au moins a une jeune individu de cette espece." It is only 

 necessary to compare the description of C. Arabicula and C. Turdus, 

 belonging to two distinct sections, and the figures of Vol. 1. 1. 7, f. 3, 

 4, and t. 12, f. 3, 4, to discover the Incorrectness of M. Duclos' ob- 

 servation. I can only observe with regard to M. Lamarck, that his 

 description exactly agrees with my shell. 



" C. controversa. — Erreur de M. Gray; c'est un individu fort grand 

 " du C. lurida; nous en possedons de semblables dans notre col- 

 " lection." If M. Duclos had said a large variety of C. Isabella, he 

 would have probably been more correct; as I have reason to believe 

 that what I have named C. controversa forms one of the remarkable 

 variations of that species produced by climate and locality. C lurida, 

 of a much larger size than the species here figured, is common in 



English collections, and cannot be confounded with it,
