 The citron Bhlimus. Shell somenhat elongately ovate, 



rather thick, either destral or sinistral, whorls six to 



seven in number, somewhat roimded, smooth, shining; 



bright citron yellow, sometimes flamed with reddish 



brown, white near the sutures, sometimes painted 



with a chesnut-black longitudinal tillet, lip and 



peritreme white.

This species is so well known by its long-established 

 name, B. citrinus, that I ha\'e hesitated to adopt the 

 Linuffian title Helix perversa, believing it probable that the 

 author of the Systema Natura;, included more than one 

 reversed species under that appeUatiou.

The bl.^ck-callous Bulimus. Shell oblong-ovate, 

 somewhat inflated towards the base, spire acumi- 

 nated, whorls six or seven in number, somewhat 

 rounded, smooth, sliining, lip expanded, widely 

 reflected ; white, stained with gi-eenish yellow, the 

 part above the cobuneUa covered with a callous 

 deep purple-black lamina, last whorl painted with a 

 longitudinal fiUet of the same colour, aperture white.

I fear there is not much diti'erence Ijetwcen this and the 



preceding species, beyond the callous purple-black lamina 

 which lines the interior of the body-whorl, aud is of some- 

 what doubtfid importance.

Linden's Bulimus. Shell cylindrically oblong, rather 

 thick, apex obtusely depressed, whorls five to six in 

 number, decussately rudely striated and finely in- 

 dented, faintly erenulated along the margin ; colu- 

 mellu one-plaited, aperture rather small, lip somewhat 

 thickened, reflected ; cream colour, sparingly streaked 

 with black, purpUsh towards the apex, and covered 

 with an olive-green epidermis, interior of the a])erture 

 Ijluish fl'hite. lip pale saflVon colour.

Notwithstanding the importance which is very properly 

 attached to the priority of names, there are exceptions, as 

 in the instance before us, in which a name may require to 

 be changed. The term leptocJmlus, or tldu-lipped, denotes a 

 character which is not found in the adult species ; the shells 

 of all Bnliini are "thin-Upped" in an immature state, and 

 many remain so at maturity ; but in the species under 

 consideration, the lip is thickened and rather widely re- 

 flected. I therefore venture to name it anew, in honour 

 of the indefatigable botanist and shell-collector, to whom 

 we are indebted for so many beautiful species of Bulinn 

 from the luxm-iant district of New Granada.
