LepipoPpLeuRuS IN NEw ZEALAND.—Some months ago we re- 
ceived numerous specimens of a Lepidopleurus from Mr. H Suter, 
collected by him in Auckland Harbor. The species seemed to us 
to be a new one; but on requesting Mr. E. R. Sykes of London to 
compare with the types of certain forms in the British Museum, he 
found it to be identical with Reeve’s Chiton inquinatus—a result 
wholly unexpected. ‘The species was described from Tasmania, but 
South Australian specimens we have seen (collected by Mr. Bed- 
nall) agree in all respects with those found by Mr. Suter in New 
Zealand.—H. A. P. 
THe Eartwrest Pusiication or Dorcasia GRAY.—In examining 
the appendix of James Edward Alexander’s Expedition of Discov- 
ery into the Interior of Africa (London, 1838), I find on p. 268 of 
volume II, a description by Gray of the genus Dorcasia and the 
species D. alexandri. This group has hitherto been dated from its 
publication in the Zeitschrift ftir Malakozoologie, 1845. Helicodonta 
sculpturata Gray (== Sculptaria sculpturata) is also described, with 
(on p. 269) two alleged Bulimi, B. hottentota and B. eulimoide. All 
were collected by the expedition about the Great Fish River in 
Great Namaqualand. JB. eulimoide apparently belongs to the Steno- 
gyra group. This publication seems to have been unknown to 
Pfeiffer and other writers on African land snails—Pilsbry. 
On THE NAMES OF CERTAIN SUBGENERA OF Helicostyla.—For 
some inscrutable reason, the writer, when considering these groups in 
the Manual of Conchology, neglected to ascertain the fact that the 
names Prochilus and Eudoxus of Albers have long been preoccupied. 
They may stand in future as follows: 
Dolichostyla n. n. (= Prochilus Alb., 1860, not of Illiger, 1811, 
Mammalia, nor of Brullé, 1835, Orthoptera, nor of Cuvier, 1817, 
Pisces). 
Opalliostyla n. n. (= Eudoxus Alb., 1850, not of Kirby, 1837, 
Coleoptera). The types and limits of the groups remain as stated 
in Man. Conch. (2), ix, pp. 229, 231.—Pilsbry. 
SrnistRAL ParuLa srRicosa.—My brother, L. M. Cockerell, 
took a sinistral P. strigosa at Norwood, Colorado. It was in my 
possession for a long while, but is now in the British Museum.
