ian side diminishes, and the other augments till the fifteenth or 

 sixteenth series. After passing through two or three transitionary 

 forms, the marginal teeth, whose cusps incline more strongly to the 

 centre as they recede from it, assume a blade-like form. Shell 

 somewhat quadrate, apex terminal, with distinct lines 01 growth, 

 crystalline, very thin, slightly concave. 



Habits very active, crawling about rapidly, but killed by a 

 few minutes exposure to bright sunshine. Found plentifully by 

 self under logs and stones at Burleigh Heads. The type speci- 

 mens I have presented to the Queensland Museum. The 

 animal, radula etc . are figured in the accompanying plate. 

 Apparently allied to Limax legrandi, Tate. (Pro Roy. 

 Soc. Tas. 1^80 p. 1G) but, as far as a somewhat brief description 

 enables me judge, specifically distinct. Possibly both may 

 ultimately be referred to forms of L. agrestis, Linn, a variable 

 and world "wide species. L. queenslandicus differs from the 

 descriptions of agrestis in having the posterior portion of the mantle 

 longitudinally instead of concentrically grooved. The remoteness 

 of the spot in which it was found from the centres of civilisation, 

 forbids any supposition that it may be an introduced species. 

 An interesting form, of which 1 only secured a single specimen 

 occurred near Curumbin Creek. Thi-s, which I rropose to record 

 as H. fraseri var. flavescens, is a shell differing in no way *-xeep, 

 in colouration from the type. The animal which it contained was 

 also strictly normal. The shell was bandless, of a uniform light 

 yellow, lip pure white. 



A few living specimens of Thersites rickmondiana Pfr. were 

 found under logs, loose sheets of bark. etc.. in the scrub-clad 

 valleys of the Curumbin and Little Nerang Creeks. In the im- 

 mature stages this shell is perforate. The animal ,vhen fully 

 expanded measures about 88 mm. in length. Anteriorly the 

 body is rounded and cylindrical, posteriorly rather flat and taper- 

 ing to a fine point. Rugosely tubereulated in front, smoother 

 behind. Colour brown with a narrow orange stripe extending 

 longitudinally along the centre of the neck, and terminating in a 

 small pit at the bases of the tentacles. Tentacles very long.
