THE VICTORIAN NATURALIST. 207 



Engjeus? A variety not yet determined. 



Genus. — The specimens taken from the banks of the Fraser Creek have 

 not yet been described. I have one specimen, dug out of the bank of 

 a creek between Shoreham and Flinders. 

 Hymenosoma lacustris, Chilton. 



This is an interestins; lind. So far this fresh-water species has only been 

 taken at Norfolk Island ; Lake Pupuke, Auckland, New Zealand ; 

 and Lake Colac and the Moorabool River in Victoria. 



Examples of the well-known sand-hoppers (Amphipods), both 

 marine and land forms, were collected, the latter being only 

 found in a few isolated spots under logs. These have been 

 kindly identified for me by Mr. O. A. Sayce, who writes : — 



" Those collected inland are identical with Talitrios sijlvaiicus, 

 Hasvvell, common throughout the scrub lands of Victoria, and 

 also in Tasmania and New South Wales. Those from the sea- 

 shore are referable to Talorchestra pravidactyla, Haswell, so far 

 only recorded from Tasmania, but I have specimens of it from ocean 

 beaches in various parts of Victoria ; how i-'.x westward it reaches 

 I am unable to say. It has not been found in New South Wales." 



The few earthworms taken prove to be indigenous species, 

 but have not yet been determined. Land Planarians were very 

 scarce, and only three species were taken — viz., Geoplana hoggi, 

 &'. munda, and G. mediohneata. 



Among the marine invertebrates, apart from the Mollusca, 

 which is being dealt with by Mr. G. B. Pritchard, there was little 

 to be found. A few examples of Echinoderms were noted, such 

 as Startish, one or two species of Sea-urchins, and some Holo- 

 thurians, including a very large species, about 6 inches m length, 

 which we frequently found imbedded in the sand at low tide. 

 The few Bristle-worms seen were similar to those taken during 

 the Shoreham excursion in March, 1902. 



CoNCHOLOGY. — By G. B. Pritchard, F.G.S. 



The first opportunity for collecting shells on the Wilson's 

 Promontory trip was at the landing-place at the south-west corner 

 of the Corner Basin, but as our arrival was timed for high tide, in 

 order to get in as close 'as possible to the shore, the first outlook 

 was rather unpromising. Shells appeared very scarce, and only 

 a few were obtained, such as Anapella cuneata, Lamarck, Ghioiie 

 strigosa, Lamarck, Ostrea ungasi, Sowerby, and Austrocochlea 

 conslricta, Lamarck. Before leavmg, the tide began to fall very 

 rapidly, owing to the general shallowness, and there were signs of 

 improved prospects, but there was no time for further investi- 

 gation, as the party was desirous of pushing on. However, on 

 the return journey this locality was in the condition of extreme 

 low tide, and vast expanses of sandy mud flats were exposed, and 

 a good opportunity was thus obtained of noting the usual species.
