439. Glessula simoni, Jousseaume. 



Glessula simoni, Jousseaume, Mem. Soc. Zool. France, vii, 1894, 

 p. 293, pi. 4, fig. 10 ; Beddome, Proc. Malac. Soc. London, vii, 

 1906, p. 172; Pilsbry, Man. Conch, ser. 2, xx, 1908, p. 61, 

 pi. 7, fig. 8. 



Original description : " Testa parva ovata, tenuis, costulata, 

 nitida, pellucida, t'ulvo-cornea, spira conoidea apice obtusiuscula, 

 sutura impressa ; anfr. 5-6 convex!, ultimus demidium longitu- 

 dinis sequans, basi vix attenuatus, rotundatis ; apertura verticalis, 

 semiovalis ; perist. rectum, tenue, acutum, margine dextra minus 

 arcuato ; columella callosa, subrecta, valde arcuata, oblique trun- 

 cata ad umbilicum appressa et depressa. 



" Alt. 3 mill. ; diam. 1*5 mill." (Jousseaume.) 



Haly. Ceylon : Slopes of Pedro, Nuwara Eliya (Simon). 



Four live specimens were taken by Simon, but two of tbem 

 were younger than the one made the type by .Tousseaume, which 

 he considered immature. 



" This minute form has about the size of a Tornatellina, but 

 seems to be more strongly sculptured than is usual in that genus. 

 The embryonic whorls are smooth, a litttle darker than the rest of 

 the shell." (Pilsbry.) The latter statement is evidently a lapsus, 

 for Jousseaume distinctly states that they are less dark than the 

 remainder of the shell, 



Genus DIGrONIAXIS, Jousseaume. 



Diqoniaxis, Jousseaume, Bull. Soc. Malac. France, vi, 1889, p. 349; 

 Pilsbry, Man. Conch, ser. 2, xix, 1908, p. 288. 



' ; Ce genre est reinarquable par son axe columellaire autour 

 duquel se deroulent deux lamelles tres saillantes, dont la plus 

 forte s'aper^oit sur tout le prolongement de 1'axe, grace a Fextreme 

 termite du test ; par son dernier tour meplan a la partie mediane 

 et sur une etroite zone circumsuturale, et caracterise par deux 

 angulosite's, dont 1'une superieure separe la zone ine'plane-tecti- 

 forme du pourtour de la suture de la surface plane mediaue, et dont 

 1'autre limite cette surface a la partie inferieure.*' (Jousseaume.) 



" A genus of uncertain position, possibly near Calaxis, as 

 M. Jousseaume believes, but differing in the longer spire and the 

 strong development of a spiral lamella superposed upon the upper 

 part of the columella. There are no parietal or palatal lamellae. 

 The internal axis, as seen through the shell, is strongly spiral, the 

 upper lamella penetrating deeply, according to Jousseaume. It 

 is possible, however, that the spiral condition is due to the basal 

 lamella." (Pilsbry.)
