1920.] H. H. Godwin- Austen : The genus Chloritis. 11 



The shell of this species {Burniochloritis kengtungensis) I have 

 now described in detail comes very close to Chloritis theohaldi, 

 Gude ' and to A nserina, Theobald,' all three from the same country, 

 the Shan States, east of the Irrawady River. 



The most remarkable distinctive character in B. kengtungensis 

 is the presence of a dart sac, and next the form of the teeth of the 

 radula. With regard to the first, in the description of the genus 

 Chloritis by Pilsbry {Man. Conch., p. 117) we find '^ Genital system 

 characterized b^^ the lack of dart sack or other accessory organ 

 on the female side " ; with regard to the second, — Basal cusps are 

 present on the lateral teeth (pi. 28, fig. 4). 



I have already referred to the two species of which the ana- 

 tomy is known, viz, dinodeomorpha and leei. Fig. 42 on plate 32 of 

 the last-named is very interesting in connection with the anatomy of 

 B. kengtungensis. On the female side a large sac is depicted much 

 in the same position as the dart sac of the Shan States specimen ; 

 it may possibly be a dart sac, it is not alluded to in the description 

 but I have not seen Mr. Hedley's original one and figures. The 

 penis with the very long flagellum is wonderfully alike in the two 

 species. Pilsbry places C. leei, Cox, in the group of C. eustoma, Pfr. 

 I must here note the section Sulcobasis of Taparoni Canefri, with 

 the type sulcosa, Pfr. (pi. 29, figs. 9, 10, shell). This in shape is 

 not unlike that of B. kengtungensis and he has described another 

 species beatricis and shows the central and inner lateral teeth to 

 lack side cusps. 



The characters of this Shan species differ so distinctly from 

 those hitherto accepted for Chloritis I consider there are sufficient 

 grounds for the creation of a new genus which I name Burniochlo- 

 ritis, in which I place theohaldi and anserina ; should leei of Aus- 

 tralia possess a dart it ma}' possibly be included.
