156 Edwin A shby : 



-of S. Aust., vol. xlii., 1918), under the name of L. liratus, Ad. 

 and Ang., and I propose now to recognise it as such. I append 

 in full the original description, as quoted by Pilsbry, Man. Couch. 

 xv., p. 101: "Shell small, elongated, convex; yellowish brown, 

 maculated with pale brown, end valves and lateral areas concen- 

 trically remotely sulcated, densely and minutely lirate, the 

 hrae closely pustulose. Posterior valve elevated, lateral areas 

 slightly elevated, median valves obtusely carinated in the middle; 

 dorsal areas longitudinally lirate, the lirae closely pustulose. 

 {girdle pale brown, densely covered with minute scales. Length 8 

 mm., width 4 mm. Yorke's Peninsula, South Australia, under 

 stones at low water." 



To this description I would add, the girdle is clothed with 

 minute, irregular, mostly rather long, scales, often placed at dif- 

 ferent angles. It has a girdle fringe of spicules, and scattered 

 spicules occur in a varying degree in different specimens. This 

 probably constitutes a first record for the State of Victoria for 

 this species. 



Mr. Sykes did not, in his paper, distinguish this shell from 

 those he identified as the following species. 



Lepidopleurus mquinatus, Reeve (Con. Icon., Reeve, pi. xxiii., 

 f. 154), of which the following is a transcription of the original 

 description. 



" Chiton inquinatus, the Solid Chiton. Shell oblong-ovate, ter- 

 minal valves, and lateral areas of the rest concentrically, some- 

 what obscurely ribbed, finely, radially grooved, central areas 

 longitudinally, finely ridged; ligament, horny, arenaceous, whit- 

 ish, stained with light brown spot along the summit of each valve. 

 Hab. — Van Dieman's Land; Dr. Sinclair. This shell is some- 

 times partially stained throughout with the faint brown colour 

 which appears on the umbonal summit." 



Mr. Sykes, in his paper aforesaid, page 86, identifies these 

 specimens, of which there is a nice series, as Reeve's inquinatus, 

 and says : — "Having had the advantage of separating the valves 

 of one of Reeves' specimens, I am able to be positive of the iden- 

 tification." 



As compared with the previous species, the granules in the 

 longitudinal ribbing are smaller, less raised, and have a smoothed 

 or planed off appearance. Perhaps the sculpture will be best 

 -described as ribs formed of strings of coalesced granules, whose 

 tipper sides are flattened, thus forming a continuous rib. The 

 idorsal area is similar in sculpture, except" that the ribbing is
