264 PROCEEDINGS OF THE MALACOLOGICAL SOCTETY. 
A rather distinctive and pretty type of colour variety, for which 
I propose the name d/anda, var. nov., is that shown in Fig. 11. The 
upper half is of a pale ochreous brown, bordered at the periphery 
by a narrow band of a rich deep chocolate colour, sharply defined at 
its lower edge, but diffused above ; there is a broad zone of the same 
shade just behind the upper margin of the peristome, somewhat 
diffused near the periphery, and a very narrow line, also of the same 
shade, occurs just under the suture; the base is similar to that of 
the type. 
Several specimens were received in October, 1899, from Mr. Rosenberg. 
Representative suites from the same source are also in the British 
Museum, and in the collections of Mr. Ponsonby and Mr. Da Costa. 
I am not aware that the species is represented in any other collections.

rounded, closely coiled, the last increasing rather suddenly, not 
descending in front; sharply angular at first, becoming rounded 
towards the mouth. Aperture oblique, s semirotundate ; peristome thin, 
straight, acute; columellar margin slightly reflexed ‘over the narrow 
umbilical perforation.

Type in my collection. 
Three specimens collected by Mr. Fruhstorfer, and received from 
him in September, 1891, as H. Jenyns?, Pir. When Pfeiffer first 
described ZZ. Jenynsi* its origin was not known. Later he indicated 
Tanna Island, New Caledonia, as its habitat.’ This was subsequently 
corrected to Tanna Island, New Hebrides. Professor von Martens 
gives Eastern Java and Querimba Island, east coast of Africa, as 
habitat; ° the former record being based on specimens collected by 
Zollinger and labelled Wanina pusilla, Mouss., in Mousson’s collection. 
The other record was based on specimens collected by Professor 
W. Peters. The New Hebrides record is an extremely doubtful one, 
for in spite of diligent search it has never been confirmed; the 
reference is probably due to a mistaken identification. There. only 
remain, therefore, the two localities Eastern Africa and Java to be con- 
sidered. Mr. Smith, with his usual courtesy, has allowed me to examine 
Pfeiffer’s types of HZ. Jenynsi in the Cuming Collection, and these 
leave no doubt as to their correct inclusion in the genus Jartensia, 
confined, I believe, to East Africa. Moreover, a couple of specimens 
from Mozambique received by me from Mr. Ancey agree with the 
1 Yava Dwipa (Barley Island), an ancient name of Java.
