from the late Mr. G. Booley, who collected much in the Andaman 

 Islands,^ differs from those specimens we had deemed to be polygyrata. 

 Accordingly, we omit the name at present. 



Where is the Male of Paludestrina jenkinsi ? — It is fifteen years since 

 F. Taylor, after cleaning out more than three hundred specimens, and finding 

 that all contained young, asked "What becomes of the males?" (this Journal, 

 vol. ix., (1900) p. 340), but, as far as I know, the answer has not yet been given. 

 C. Oldham (idzd., vol. x. (1901) p. 42) records the same experience. In September, 

 1915, I met with the species in a pond in Hertfordshire, near Elstree, and having 

 found fry in about one hundred consecutive specimens, searched systematically for 

 males. In December no jenMnsi could be found, and in March only a few, but in 

 June, July, and September, 1916, they were fairly abundant again, and had evi- 

 dently bred, as on the last occasion the majority were quite juvenile. The large 

 specimens always contained young, more or less developed ; among the smaller 

 ones there are, of course, a good many without obvious fry, but after examining in 

 more or less detail some three hundred specimens I have been unable to find a male 

 or hermaphrodite individual. All the specimens were of the plain, noncarinate 

 form. If the species is really parthenogenetic the matter is worth attention ; 

 perhaps someone else can solve the difficulty. The condition is possibly found 

 only in fresh water. May I also suggest that notice should be taken of the per- 

 sistence of this species in any given locality ; there seems to be some evidence that 

 it is prone to die away after a few years, and such disappearances may be con- 

 nected with its mode of reproduction. One is reminded of Elodea. — A. E. Boycott

Hibernation of Succinea elegans Risso. —I was surprised to find a number 

 of immature S. elegans hibernating under bark of a dead willow, some four or five 

 feet from the ground, in a swampy part of Minehead Warren. They were asso- 

 ciated with Claiisilia bidentata and Pupa cylindracea, rather an unusual gathering.

Lienardia mighelsi nom. nov. — We propose this name for the Sandwich 

 Island shell named Pleurotoma rugosa by Mighels, Proc. Boston Soc. Nat. Hist., 

 vol. ii., p. 23, 1845, ^s the name is doubly invalid, having been twice used for 

 fossils — by I. Lea, Contrib. to Geol., 1833, p. 136, pi. 4, i. 130; and by Des- 

 hayes, Descr. Coq. Fossiles Env. Paris, vol. li. , Moll., p. 486, 1834. As a variety 

 Bouge and Dautzenberg(p. 188) class the shell named by G. and H. Nevill cunu'io. 

 They gave the reference as " Clathiirella riigosa var. cnrculio G. and H. Nevill, 

 Journ. Asiat. Soc. Bengal, 1875, p. 86." It should be " Pleurotoma ctirculio 

 G. and H. Nevill, Journ. Ceylon Branch Royal Asiatic Society 1867-70, pt. i., 

 p. 142, 1870 : Balapitiya, Ceylon." We do not consider this varietal at the pre- 

 sent time, but we hope later to study authentic material. We have provided the 

 above name as it may be years before the complex problems surrounding these 

 small Turrids are worked out, and in the meantime a name is necessary for this 

 common Indo-Pacific shell. — T. Iredale and J. R. le B. Tomlin {Read before

I Melvill and Sykes : Marine Shells from the Andaiiians, IL Proc. Mnlac Soc, vol. iii., 

 p. 42, where polygyrata Desh. is reported from the Philippine Isles and Japan. Twenty-two 

 Terelirce are enumerated from the Booley Collections ; of these only babylonia, cceriilescens , and 

 nitida occur in the Persian Gulf region, unless indeed serotina lie considered a variety of 

 straminea Gray. This last occurs in the Andamanese group.
