90 THE VICTORIAN NATURALIST. 



list became almost obsolete, consequently in 1897 Mr. G. B. 

 Pritchard and myself undertook the preparation of a complete 

 catalogue of the Victorian marine mollusca, with full synonomy 

 and notes. This has been published from time to time in the 

 " Proceedings of the Royal Society of Victoria," the sixth part^ 

 completing it to the end of the Gastropods and enumerating 531 

 species, having been published in February last ; but even durmg 

 the publication of the new catalogue additional species have been 

 found and described. These will be dealt wilh later on in a 

 similar manner to those already catalogued, giving references, 

 habitat, observations, &c., but in the meantime h has been 

 thought desirable to publish the names of the additional 

 species, amounting to 41 in all. These, which include several 

 types, I am exhibiting to-night, but special attention might be 

 called to the following as being particularly noteworthy : — 



Truncaria australix, Angas. — Described in 1877, found in 

 New South Wales. So far I have only obtained three specimens. 



Mitra pellucidn, Tate. — This is a very small white shell, from 

 4 to 8 millimetres in length, and is, as its name denotes, 

 pellucid. 



Columhella Jilosa, Angas. — This was described in 1867, having 

 been dredged in Port Jackson ; it is an interesting form, being 

 spirally lirate. The specimens exhibited were dredged in Western 

 Port. I had some others and placed them with larger shells on 

 the roof of an outbuilding to become deodorised. 1 noticed that 

 the sparrows often hopped about these shells, and when I brought 

 them in found that the small ones had disappeared, and could 

 only conclude that the birds had devoured them. 



Donovania Jenestrata, Tate and May. — This is the first record 

 of the genus having been found here, and the species is one 

 recently described. The type was obtained on the east coast of 

 Tasmania. 



Co7ius apbtst7-e, Reeve. — This species makes the fourth in the 

 genus that has been found on our shores ; it was described in 

 1843, and is recorded as occurring in New South Wales, New 

 Zealand, and Cape of Good Hope. The shell is somewhat solid, 

 usually about i inch in length, and may be readily distinguished 

 from our other species by its broader form and encircling dotted 

 lines of colouration. 



1 have been enabled to add the four additional sj)ecies of 

 Triforis through the kindness of Mr. Chas. Hedley, Conchologist, 

 Australian Museum, Sydney, who has been studying the New 

 South Wales representatives of the genus. Having published his 

 results in the " Proceedings Linnean Society N.S.W.," part iv., 

 for 1902, he was good enough to send me examples of some of 

 the species for comparison, and I was thus enabled to identify 

 four more as species found in Victorian waters.
