NEW SOUTH WALES MOLLUSCA, 



by fine concentric sculpture. There is no trace of epidermis. 

 A large specimen measures, height, 2 ; length 2-3 ; breadth of 

 single valve "8 mm. 



Loc. — In sand, Bondi, Watson's Bay, Middle Head and 

 Balmoral, all near Sydney. Its association with such shells as 

 CcecuTn amputatum suggests to me that it inhabits deep water. 



Type to be presented to the Austi*alian Museum. 



I consider the shell described as adult, because a considerable 

 series of specimens show little variation in size. This species is 

 perhaps the smallest Australian pelecypod yet described.

(Fig. 3.) 



The recent storms cast 

 ashore on the Middle Har- 

 bour beaches numbers of 

 Solen sloanii, weakened pro- 

 bably by theunusual quantity 

 of fresh water which heavv 

 rains had poured into the 

 bay. As this species is gejie- 

 rally hard to procure in the 

 flesh, and as no mention 

 appears to have been made 

 of its soft parts, I took the 

 opportunity to make the 

 accompanying notes and 

 sketch. 



Foot pi'otruded for more 

 than one-third of the shell's 

 length, white, clavate, later- 

 ally compressed and pointed 

 distally. Mantle entire, ex- 

 tending the whole length of 

 the shell, notched at either end, edges not papillose. Siphons 

 white with a brown base, united to the tips, orifices fringed
