Sypharochiton pellisserpentis maugeanus, Ire. and May, 

 This, as before remarked, was one of the most numerous 

 species and most variable, many being handsomely mottled 

 with white, and one, almost entirely white, whereas others 

 were almost black. There was a great variation in sculpture 

 also, from strong ribbing throughout the pleural areas to 

 those in which this area was practically smooth. I cannot 

 help questioning the wisdom of separating the Tasmanian 

 shell from pellisserpentis, Q. and G., for its exceptional 

 habit of variability, both in sculpture and colour markings, 

 suggests that there are no constant sub-specific differences. 



Lorica cimolea, Reeve. One or two specimens only. No 

 doubt rather rare in this locality. 



Additional Species collected at Woodbridge. 



Woodbridge is, as before stated, much further north, 

 though still in the Channel, and while most of the species 

 collected at Lunawanna were found here, there were some 

 notable exceptions and some very fine additions. 



Among the exceptions m.ay be cited that of Rhyssoplax 

 oruktos, Maughan, and the green variety of Haploplax mayi, 

 Pilsbry, neither of which were here present. No specimen of 

 Acanthochiton costatus was found, but it is evidently a rare 

 species, generally. It is quite possible that a further search 

 at Woodbridge would reveal it. The most noteworthy find 

 at this place was that of thre^e different species of the genus 

 Callochiton. This probably easily constitutes a word's record; 

 three distinct species of this genus at the same locality on 

 the- same day. 



Callochiton platessa, Gould. Oile small and rather 

 abnormal specimen was found. Instead of the regular con- 

 vexity of the median valve the outer half is flattened or slightly 

 concave. 



Callochiton mayi, Torr. One specimen of this striking 

 and rare species was found here and thereby considerably 

 extending its range. Mr. May writes me that he dredged 

 it in about nine fathoms off Pilot Station, just within the 

 northern end of the Channel; it is doubtless a deep-water 

 shell. The only other locality in Southern Tasmania known 

 is Port Arthur, and there it is very rare. 



Callochiton elongatus, May. This striking diminutive 

 Callochiton, with its spoon-shaped girdle scales, has pre- 

 viously to this find, been only known to occur at Port Arthur 

 and Norfolk Bay, and then only taken by Mr. Mawle, who 

 supplied them to Mr. May for description. The girdle in 

 life is broad but very thin and delicate, the general colour- 

 ation of both shell and girdle being a bright pink, forming a
