NOTES. 73 



P. fiihyeana and P. paitensis, and P. avtensis was united with 

 P. pcdiculus, Shuttl. A little note on the value of the name 

 Laimodonta j (which he emends to Laemodontd), by the present 

 writer, seems also to have escaped his notice. 



In conclusion, it need only be remarked that it is very much 

 easier to endeavour to find mistakes in such a catalogue than to 

 compile it, and that only those who have studied a fauna, so 

 difficult as that of New Caledonia, are able to appreciate the 

 time and labour involved in the work, of which Mons. Crosse 

 has so successfully completed the major portion.

NOTES. 



Locality of Clausilia recondita, Sykes. — This ClausiUa, recently des- 

 cribed {ante, vol. iii., p. 48), from Sumbawa, has now been found among some 

 shells collected in Gilolo. E. R. S. 



Arion hortensis, var. caeruleus. — I have recently received from Mr. 

 B. B. Woodward a number of specimens of Arion hortaisis, Fer., from his 

 garden at Ealing. Amongst these I was interested in finding two examples 

 of the var. caeruleus, which I described some years ago (Conchologist, 1892, 

 vol. ii.). The most southernly record I have previously had was near Oxford, 

 where I collected it in 1890. Walter E. Collinge, F.Z.S. 



Note on Scacchia eddystonia, Marshall. — Having recently received 

 a large quantity of sand, trawled off Plymouth, I examined it very carefully, 

 in the hope of finding the small bivalve which Mr. Marshall described under 

 the above name, in the " Journal of Malacology " for June last. A few valves 

 were found agreeing exactly with Mr. Marshall's description and the admir- 

 able figures accompanying his paper (except that one valve is perfectly 

 hyaline). But it was at once seen not to be a Scacchia at all, for although the 

 shells closely resemble in shape 5. elliptica, Scacchi of the same size, the 

 hinge is utterly different. Moreover, the description given by Mr. Marshall 

 is incorrect. The " two " cardinal teeth of which he speaks are really a single 

 cleft cardinal, whilst his " lateral " is another simple cardinal. The hinge is, 

 in fact, that of an absolutely typical Diplodonta. A reference to Jeffreys' 

 " British Conchology " shows that the fry of D. rotundata, Montg., are 

 evidently remarkable, for Jeffreys himself described young examples of the 

 species, under the name oi Diodonta barleei, in the " Annals and Magazine of 

 Natural History " for 1S58. The description of this Diodonta barleei is brief 

 and the outline of the figure not very good, but the hinge is admirably shown, 

 and it is easily identified with Scacchia eddystonia. I have been able to satisfy 

 myself that it is in reality the fry of Dip. rotundata, Montagu, by an examina- 

 tion of the umojnal region of young specimens of the species kindly sent by 

 my friend, Mr. H. K. Jordan, F.G.S.
