Melania (Striatella) crepidinata, Reeve. 
Found in Java and Borneo (Geale). 
Melania (Striatella) tuberculata, Mull. 
Melania turris ?, Geale. 
The specimens are very young and aciculate, therefore not to be easily identified. M. turris is from 
Borneo. 
The following species, except one which may be new, have a wide distribution:— 
Neritina dubia, Chemn. 
Neritina turtoni. 
Neritina soverbii, Recluz. 
Neritina diadema, Recluz. 
Pythia undata, Lesson. 
Cassidula mustelina, Desh. 
Cassidula bicolor, n. sp. 
This is a smaller shell than sulculosa, Mouss., to winch it is nearest as regards the form of the 
aperture, but it is not so strongly formed. The body-whorl is crossed by shallow longitudinal plications. 
The colour is a very dark sepia-brown, with two broad parallel very white hands, which extend to the 
outer margin of the peristome. I could find nothing like it in the British Museum collection. 
Melampus fasciatus, Desh. 
Auricula auris-jud^:, Linn. 
TWO PAPERS ON A PORTION OF THE COLLECTION OF COLEOPTERA 
MADE BY Mr. JOHN WHITEHEAD IN NORTH BORNEO. 
[From the ‘ Proceedings of the Zoological Society of London/] 
ON NEW GENERA AND SPECIES OF COLEOPTEROUS INSECTS FROM MOUNT 
KINA BALU, NORTH BORNEO. By H. W. BATES, F.R.S., F.Z.S. 
The following descriptions contain the results of the examination of a portion only of the collection 
of Coleoptera made by Mr. J. Whitehead during his recent visit to Kina Balu. The Coleoptera comprise 
an unusual proportion of new and remarkable forms. 
Family Cicindelid2E. 
Therates whiteheadi. 
Th. spectabili (Schaum) similis et affinis, sed differt, inter alia, oculorum pedunculis fere verticalibus 
fronteque angustiore. E majoribus, nigro-viridis, elytris viridioribus : thorace angusto, late- 
ribus medio minime rotundatis : elytris apice longe spinosis, spinis divaricatis et oblique elevatis, 
ma rgin e exteriore versus spinam continuo nec emarginato, angulo suturali distincto etsi 
rotundato, deinde margine usque ad spinse basin minus obliquo : dorso sicut in Th. spectabili 
multituberoso, vittula liumerali calloque obliquo disCoidali albo-testaceis : pedibus nigris, coxis 
femoribusque basi et subtus albo-testaceis: abdominis margine et apice rufo-testaceis. Labrum 
margine antice $ 8-, $ 6-denticulatum. Long. 16 millim. 
This beautiful species differs from Th. spectabilis (Schaum) and princeps (Bates) in the more verti¬ 
cally elevated peduncles of the eyes, which position perceptibly narrows and deepens the forehead between 
them. It also differs in the outline of the apical margin of the elytra, the suture forming a distinct 
though rounded angle, whence to the base of the spine the apical margin is not continuous with the
