error, as well as the two following varieties: Poliigyra Ihyroides, Say, v. hucculenta, 

 Gld. , P. palliata, Say, v. alba, Currier. The following six species and two varieties 

 are additions to the fauna: iitrohilops affinis, Pils. , Vitrea %oheatleyi, hid., Gastro- 

 donta intertexta, Binn., G. demissa, Binn., Agriolimax agrcstii, L., Pohjgyra

 sijius V. pohjgyratus, Pils. 



Many interesting notes are given on the distribution. — W. E. C.

 Zealand Land RIollusca. rroc. Malac. Soc. Lond., 1899, vol. iii, pp. 286 —

Mr. Suter here describes and figures the following: Endodonta (Charopa) 

 otagoensis, and subinfecta, Flammulina (Pyrrlia) virescciis, F. (Phacussa) ful- 

 'iiiiiiata, Hutt., var. costata, F. (P.) henryi and Parypharita cdivardi. Figures 

 of the terminal ducts of the generative organs of F. vircscens and F. henryi are 

 given in addition to figures of the shells, jaw, and radula. — W. E. C.

From an examination of the generative organs, jaw and radula of this species, 

 the author finds that it is closely related to ISitala antlwopopltagortim, and is of 

 opinion that its proper place is in the genus Medyla, Albers, sect. Euplecta, 

 Semper. — W. E. C.

Mr. Suter's synopsis of the New Zealand Polyplacophora will prove very useful, 

 as also his revised classification of the New Zealand Pleurotomida;. This latter, 

 being based entirely upon the characters of the shells, is, as the author states, open 

 to amendment. Twenty-six species are enumerated, of which the following are 

 new : Surcula verrxicosa, Mangilia subaustralis, M. flexicostata, Clathiirella sub- 

 abnormis, 0. nodicincta, and Daphncl/a sub.striata. Figures are given of the new 

 species. In all cases the location of the type is given and the reference to the 

 original description and figures. — W. E. C.

 pis. I— 12. 



This paper fully maintains the high standard set up in part I. Twenty-seven 

 new species and five new varieties are described and figured, and many valuable 

 critical notes are given on the various species dealt with. Not a few paleontologists 

 will differ from the author in uniting Athleta tuomeyi, Conrad, with Volutilithes 

 petrosus, Conrad : even supposing there are not sufficient characters of importance 

 to warrant sub-generic distinction, the specific characters are very pronounced, on 

 the other hand Syrnola insignijica. Aid., is very rightly regarded as synonymous 

 with .S'. trapaquara, Har. , which species seems very different from Cossmann's 

 propeaeicula. 



Of the new species, Levifusus indentus is an interesting form somewhat approach- 

 ing forms of Z. prngoda, Heip., but very properly separated from that species. No 

 doubt future work will bring to light other forms of this new species which will, we 

 think, further separate it from L. pagoda, and clearly mark it off from any of the 

 many varieties of Fidgur spiniger. 



Not the least valuable part of Mr. Harris' work is to be found in the careful 

 reproduction of the original descriptions of the various species enumerated. — W.E.C.
