certainly be congeneric with the Australian H. Cuvieri, the type of 

 the genus. It has been shown that the glassy shells commonly 

 referred to Jlelicarion cover very differently constituted animals. 

 I note that tlie coiling of the Indian shells, for instance, is quite 

 regular, and quite unlike the rapidly increasing, somewhat excentric 

 coiling of the present species, wliich agrees with Australian shells. 



In "the Trans. New Zeal. Inst., vol. xvi, 1883, p. 204 (1884), 

 " Vitrina Kermadecensis, Pfr." is included in the New Zealand List 

 as occurring at " Hobson's Glen, Auckland (T. W. Kirk)". This 

 record is quite untrustworthy, as no other worker has found it in this 

 locality ; secondly, on the same authority European shells such as 

 Neritina fliimatilis were recorded from the Wanganui River; and 

 thii'dly the specimens described by Smith were forwarded to him 

 by a close relative of T. W. Kirk, so that an erroneous locality might 

 have been easily added. 



Genus Fanulum, nov. gen. 



This name is proposed for the small group of molluscs typified by 

 Trochoyianina exposita, Mousson, and which includes Helix msculpta, 

 Pfr., and Medyla imitatrix, Sykes. They have obviously little 

 relationship with Trochona^ihia, and cannot remain in Medyla. 

 My friend Mr. G. K. Gude has pointed out to me that the genus 

 Medyla was proposed by Albers [Die Heliceen, 2nd ed., 1860, p. 47) 

 to replace Vitrinella, Gray, which was preoccupied by C. B. Adams, 

 and as type was designated Nanina viridis (Quoy). In the Gen. 

 Rec. Moll., vol. ii, app., p. 642, 1858, Albers, however, was 

 anticipated by H. and A. Adams, who had provided Otesia for 

 exactly the same group. Conse([uently Medyla is quite unavailable. 

 In the Proc. Malac. Soc, vol. iii, pp. 330-3, 1899, Suter gave some 

 anatomical notes upon H. msculpta, Pfr., and referred it to Medyla 

 {JEu'phcta), and wrote that, on account of anatomical similarities, 

 Kaliella, Sitala, Coneiipleda, and Euplecia would probably be best 

 regarded as sections of one genus. The same writer later, in the 

 Index Faimm Norm Zealandia, 1904, p. 63, referred to the Kermadec 

 species a,?, Medyla {Coneuplecta). Under such conditions, and inasmuch 

 as I do not advocate the lumping of such diverse groups as regards 

 shell characters, I am putting forward the above new name.

Hah. — Sunday Island, Kermadec Group. Living on the ground 

 in local scattered colonies on the underside of rotten nikau palm 

 leaves, only on the higher ground. 



This species, as previously stated, was characterized by its occurrence 

 gregariously in a few widely separated colonies. It was found on the 

 highest point of the island, occurring as an aberration of a white 

 colour, the regular colour being brown, and living under rotten logs 

 in a solitary manner. The few specimens collected seemed somewhat 

 more flattened, but some more conical ones were included, so that the 

 only appreciable difference to grasp is the coloration. Yet the
