572 NOTES ON SPECIES OF CYPR/EA, 



abruptly declining in front, and the posterior end more deflexed; 

 the base also is more convex ; the aperture is straighter; the 

 dorsum is of a rosy-yellow hue sprinkled over with small macular; 

 the lateral spots are also smaller." 



Ohs. — "A more solid shell than a nc/ list at a and Compfo?ii, with 

 a peculiar deflexion of the anterior extremity, which slopes from 

 the back, and it is of a light c^jlour sprinkled over the back." 



The finest specimen of this species I have seen is in the collec- 

 tion of Dr. J. C. Cox, of Sydney, N.S.W. Specimens before me 

 differ a good deal in shape and size, but I describe and figure 

 three examples. 



The first (fig. 12) is lighter in colour than most specimens, and 

 is more cylindrical than any withers I have seen. It measures, 

 from the syphonal end to the posterior apertural notch 27 mm., 

 18 mm. wide and 13 mm. high. Colour pale bluish on the dorsal 

 surface, which is covered with minute blurred spots; a slight 

 dorsal sulcus covered with dark chocolate spots, very few of them 

 showing on the base of the shell; a few spots on the left side of 

 the shell, none showing on the base, which is of a dull white; 

 with 26 teeth on the right culumellar margin sloping into the 

 aperture; those on the left very fine, not showing on the base. 



The second (fig. 13) is more pyriform in shape; measuring 25 

 mm. long, 16 mm. wide and 13 mm. high. Dorsal surface is 

 much darker, being a rich chocolate brown formed by minute 

 dark spots which under the lens seem to run into each other; the 

 dorsal sulcus with smaller and fewer spots on it than in the first 

 example (fig. 12); base white, rounded; the toothing about the 

 same as in first case (fig. 12) Itut on the left side of the shell a 

 little stronger and more visible. 



The third (fig. 14) is the smallest specimen of the three; 

 measuring 21 mm, long, 16 mm. wide, and 12 mm. high. Colour: 

 the dorsal surface pale drab flecked with irregular spots; a very 

 strong dorsal sulcus, with a few darker spots on it, none of them 

 showing on the base which is a very pale brown. The toothing 

 on the right columellar margin stronger, extending well across 

 the base; on the left very little of the toothing is seen.
