Paheontology of Older Tertiary of Victoria. 97 



Length, 9 mm. ; brecadth, 5 mm. ; length of spire, 5 mm. 

 The author in his remarks refers to the analogy of this species to 

 Triton quoyi. Reeve, a common Southern Australian living 

 species, the comparison being certainly a valid one. Also its 

 small size for the genus, its remarkable mouth, "as it is murex 

 like, dentate and almost entire." He further states that "Pro- 

 fessor Tate regards this shell as a young Ranetla belonging to 

 the section in which the varices are not continuous." 



This species is figured on Plate XXI., Fig. 15, of the above 

 work, and though the figure is not a good one, it serves to 

 indicate the shell fairly. 



I should now like to draw attention to Professor Tate's 

 description of Triton gemmulatus, in Part I. of the Older 

 Tertiary Gastropods, as follows: — "Shell turriuulate, with a 

 distorted spire of seven convex whorls, ending in a large blunt 

 apex of two and a half smooth whorls, with a tip very small and 

 rather depressed. Spire whorls (excepting the apical ones) 

 irregularly convex, being ventricose in front of, and nearly flat 

 behind, each varix ; ornamented with about 16 unequal lirae, of 

 which there are two prominent ones on the periphery, crossed by 

 about 15 faint intervariceal costulations which bear bead-like 

 granulations at the intersections ; the intercostal spaces distantly 

 transversely striated. 



" Varices eight, at intervals of about four-fifths of a whorl, 

 stout, broad, crossed by the lirae, and axially striated. 



" Last whorl convex, with a rounded base contracted into a 

 short twisted beak ; ornamented same as that of the spii*e, except 

 that the transverse striations cut up the surface of the lirfe into 

 small granulations. 



" Aperture subrotund, entire ; outer lip with an acute crenu- 

 lated margin, lirate within ; inner lip reflected, smooth, with an 

 oblique fold at the front. Length, °1 3 ; breadth, 6 ; length of 

 aperture, 4 ; of canal, 2." 



Professor Tate in his remarks compares the fossil with the 

 recent Triton quoyi. Reeve, and notes the distinguishing 

 characters. His type specimen is from the same locality as T. 

 pratti, T. Woods. Professor Tate's figure 8(r, ^, on plate 6, of 

 Gastropoda, Part I., appears to be a somewhat more finely 

 ornamented example than that delineated by T. Woods, as the
