Subgenus KHYTIDOPSIS Aucey, 1882. 





Ehi/tidopsis Le Naturaliste 1882, p. 85 ; ANCEY, Bull. 



Soc. Mai. Fr. V, p. 371, 1888. 



Shell globose-depressed, narrowly umbilicated, thin but rather 

 strong. Whorls about 5*, slowly increasing, the last rounded at the 

 periphery. Aperture subvertical, oblong-lunate ; lip sharp, gently 

 sinuous below, dilated at the columella. Type H. chelonites Crosse, 

 pi. 6, figs. 69, 70. 



Jaw widely arcuate grooved by 18 indistinct rather wide lamellre 

 which denticulate its cutting edge. 



Lingual ribbon 1 mill, long, mill, wide; teeth according to the 

 formula 12-8-1-8-12. The central teeth are as large as the lateral, 

 tricuspid, the side cusps small, median cusp elongated. Lateral teeth 

 having a rudimentary entocone, a large mesocone, and a sloping 

 bicuspid ectocone. Marginal teeth forming an angle with those of 

 the middle field, they are spaced, gradually increasing, and bear 

 three cusps, the entocone and mesocone being united toward their 

 bases, the ectocone smaller. 



Our knowlege of the dentition of H. chelonites rests upon a note 

 by Saint-Simon, in Bull. Soc. d'Hist. Nat. de Toulouse 1880, pp. 171, 

 174. The jaw and teeth agree well with those of other sections of 

 the genus Flammulina, but whether a caudal mucous gland is present 

 or not remains to be ascertained. Ancey's name appeared anony- 

 mously in 1882. It is not easy to decide what effect this should 

 have on nomenclature.
