interest, though their precise affinities are as yet uncertain. In 
any case they cannot be regarded as typical members of the 
Zonitide, though an aggregate of anatomical characters exhibits 
the characters of that family. An account of the anatomy of 
Papuina litwws (Lesson) is given, and discrepaney between the 
anatomical and conchological relationships of a new species of 
Papuina is discussed.

Mr. K. G. Buatr, B.Se., read his report on the Heteromerous 
Coleoptera collected by the British Ornithologists’ Union and the 
Wollaston Expeditions in Dutch New Guinea. 
The most interesting feature of the collection, from the point 
of view of distribution, is the occurrence of Cissites maxillosa Fab. 
iu thisregion. This beetle has been hitherto regarded as peculiar 
to the Oriental Region, its range extending from Assam to Java, 
Borneo, and the Philippine Islands; it has alse been found in 
Ceylon. 
The three species of Amarygmus belong to a section of the 
genus that makes New Guinea its headquarters ; a few species of 
this section are found in the extreme north of Australia, but the 
majority of the Australian species belong to other groups. 
Of the fourteen species noted, seven are described as new.

Palatal growth in mouth of Camel. 
Mr. R. H. Burne, M.A., F.Z.S., exhibited a specimen of the 
palate of a female Bactrian Camel (Camelus bactrianus) and a 
lantern-slide of a dissection of the throat of a male Common 
Camel (Camelus dromedarius)* (text-fig. 1), and drew attention to 
a pendulous outgrowth from the roof of the mouth. 
This outgrowth or palatal appendage is situated several inches 
in front of the free posterior border of the palate and is 
continuous on either side with the anterior pillars of the fauces. 
It is rudimentary in the female, but of large size in the male 
where it forms a great flaccid mass of tissue 11 inches (28 cm.) 
long, hanging down the throat for some distance beyond the 
larynx. 
Short accounts of this appendage are to be found in many of 
the older anatomical text-bookst, and it has recently been briefly 
described by Prof. Lesbre in his monograph on the anatomy of 
the Camel =. 
It is a secondary sexual organ which during rut, when the 
animal is excited, is protruded from the mouth “to the accom-
