white of the under surface, and marked in front of the dorsal fin by a 
brown crescent. Between Java and Borneo was procured another new 
species, Delph. Malayanus, of a uniformly cinereous colour. Several 
other species which appeared to be new, including the Delph. minimus, 
the Delph. maculatus, and the Delph. leucocephalus, were observed 
sufficiently to enable the voyagers briefly to describe them, but no speci- 
mens could be obtained, and no figures are consequently given; but 
representations of the whole of the others enumerated above are con- 
tained in the Atlas of Plates. 
With the Mammalia we terminate for the present our analysis, pro- 
posing to resume it when the text shall have proceeded so far as to enable 
us to give in one article a sufficient view of the whole of the ornitho- 
logical department of the work. The text now before us embraces only 
general remarks on the ornithology of the several places at which the 
expedition rested, and does not descend to particulars as to the new 
species and forras which were observed. Many of these are extremely 
interesting, as is evident from the beautiful representations of them con- 
tained in the accompanying Atlas. 
A Systematic Catalogue of British Insects ; being an Attempt to arrange

natural affinities. By J. F.StepuEns, F.L. and Z.8., §c. 8vo.

In this enumeration of the species of indigenous Insects, Mr. Stephens 
has furnished us with a condensed view of the results of his entomological 
labours during nearly twenty years devoted sedulously to their collection 
and examination. At the period when his enquiries commenced the 
most extensive lists of British insects in which all the orders were in- 
cluded, were those contained in Berkenhout’s Synopsis, in Stewart’s 
Elements of Natural History, in Mr. Donovan’s expensively illustrated 
Natural History of British Insects, and in the indications of Dr. Turton’s 
English edition of the System of Linneus. In the latter alone did the 
number of species pointed out as natives of this country approach to even 
one-fourth of that contained in the present catalogue. We had, how-
