FASCICULI MALAYENSES 
Mr. E. R. Sykes was good enough to compare it with specimens of 
Hemiplecta in the collection of the British Museum, and he informs me that 
there is one smaller specimen, unnamed, from Kelantan. 
I have much pleasure in associating with this interesting variety the name 
of one of the distinguished Directors of the Berlin Museum, Professor E. von 
Martens. 
TROCHOMORPHA, Albers. 
12. Trochomorpha timorensis, v. Marts. 
Trochomorpha timorensis, v. Marts. Preuss. Ost.-Asiat. Exped. Bd. ii, p. 248 
(1867) ; Stoliczka^ J. A. S. B. xlii, p. 22, pi. i, fig. 17 ; pi. ii, figs. 10-12. 
Bukit Besar, Nawngchik. 2,500 feet. 
SITALA, A. Ad. 
13. Sitala in-fula (?), Benson 
Sitala infula, Benson.^ Ann. Mag. Nat. Hist. 1848, p. 160, 
Bukit Besar, Nawngchik. 2,500 feet. One specimen. 
This has the general outline of S. Infula.^ Bens., but the first five whorls 
have each a single well-marked spiral rib, while the last whorl has two. 
There is a specimen of the same species (unnamed) in the British Museum, 
from Kelantan. 
CHLORITIS, Beck. 
14. Chloritis malayana (Mlldff.) 
Helix (Trachia) malayana, Mlldff. J. A. S. B. Iv, p. 303 (1886). 
Chloritis malayana, Mlldff. P.Z.S. 1891, p. 335, pi. xxx, figs. 6, 6a. 
Gedong, Batang Padang, South Perak. 
This species was described by Dr. Moellendorff, in 1886, as a Trachia^ 
but later, in 1891, he removed it to the genus Chloritis., Beck. I must leave 
others, who are more conversant with the two genera, to decide as to which it 
belongs, but I should here like to point out the relationship, so far as the 
generative organs are evidence, between this species and Prachia penangensis^ 
Stoliczka. 
The jaw is quadrant-shaped and exhibits twelve strong ribs, and one or 
two less distinct lateral ones. The radula is very similar to that of T. Penang- 
ensis^ only the central tooth is larger, as also the laterals, and the basal plate 
smaller.
