Neumayr ' in describing F. kreitneri alluded, as we have 

 already stated, to the pecuHar form of the central tooth, but did 

 not regard this character as of generic importance and placed the 

 species in the genus Lithoglyphus. This genus is made the type 

 of a subfamily by Fischer,* who describes the Lithoglyphinae thus : 

 " Pied simple ; plusieurs denticulations basales ; verge simple ou 

 fourchue; opercule corne, spiral ou subspiral. " The only other 

 species from China ascribed to Lithoglyphus is L, liliputanus, 

 Gredler, of which there are specimens (apparently cotypes or 

 parat3^pes) in the Museum collection. We have extracted the 

 radula from one of these and find it differs little from that of the 

 European L. fuscus. The radular teeth of L. fuscus have been 

 figured by Troschel.^ Our preparation differs from his figure only 

 in having the chief denticulation of the lateral tooth relatively 

 larger. We figure the teeth of L. liliputanus and L. fuscus for 

 comparison with those of F. kreitneri.

The only known species has experienced some vicissitude of 

 nomenclature at the hands of three authors who have described it 

 under as many generic and specific names. Heude described it 

 as Fenouilia bicingulata, gen. et sp. nov., while Fulton called it 

 Jullienia carinata. We have been able to compare specimens 

 named by Fulton with topotypes of Neumayr's species. 



Heude's original description of the genus (1889) ran as 

 follows: — Testa trochoided, imperforatd ; operculo corneo, pauci- 

 spirali, nucleo basali. Animali prohabiliter rissoino. lyater (1890) 

 he added, radula j. i. j., Lamina media integrd, laterali pauci- 

 dentatd. So far as it goes, this is a correct description of the shell, 

 operculum and radula, except that we read the dental formula 

 2. I. I. I. 2. Heude, moreover, published in 1890 some good figures 

 of the soft parts drawn by Rathouis, and most of these we have 

 been able to substantiate by dissecting specimens from Mr. Coggin 

 Brown's collection. Our examination of specimens diagnosed as 

 male by a microscopic examination of the gonad shows that the 

 vas deferens ends in a simple pore the margin of which is not 

 even invaginated. The peculiarities of the head and branchial 

 chamber to which we have alluded are also clear.
