ENDODONTA. 29 



Subgenus BRAZIERIA Ancey, 1887. 



Brazieria ANC., Conch. Exch. ii, p. 22, August, 1887. Not Bra- 

 zieria Petterd, Proc. Roy. Soc. Tasin. for 1888, p. 76 (Amnicolidce). 



Shell depressed, narrowly but openly umbilicated, ribbed above, 

 smooth and shining beneath. Whorls 43-5, the earlier li reticu- 

 lated (fig. 51), the last strongly keeled. Aperture securiform, lack- 

 ing internal lamellae. Peristome thickened within, obtuse, the pari- 

 etal callus elevated into an erect tongue-like transverse process. Type 

 H. velata Hombr. & Jacq., pi. 5 ; figs. 49, 50, 51. 



Soft parts unknown. The specimens before me were collected by 

 Mr. John Brazier at Lugunar, one of the Caroline Islands. He 

 found it also at Hagolu, Carolines, whence Hombron and Jacqui- 

 uot procured it. We cannot regard the generic relationships of 

 this snail as established until the soft parts are investigated ; it may 

 prove to belong to Zonitidce. The elevated parietal tooth is formed 

 on the plan of that of Polygyra cereolus, etc. 

 E. velata H. & J. iii, 61.

Shell pup if orm, cylindrical, the altitude nearly double the diame- 

 ter ; apical end obtusely rounded ; base slightly wider, convex, nar-

 edge (pi. 8, fig. 2). 



Radula consisting of about 90 straight transverse rows of 11-5- 

 1-5-11 teeth. Central tooth tricuspid. Lateral teeth larger, simi- 

 lar to the centrals, but slightly asymmetrical and with longer meso- 

 cones. Marginals broad, the 6th to 12th tricuspid, the mesocone 

 largest; 13th to 15th with four cusps, the ectocone being split, mes- 

 ocone still longest ; last marginal with one broad low cutting point
