758 The American Naturalist. [September, 
feet 3 inches in length. Horns robust, turning outwards, forming a 
complete crescent when looked at from before; some 12 or 15 annuli 
on the lower half, upper half smooth; the characteristic hartebeest 
zigzag is only faintly reproduced. Selous has noted a hybrid between 
the tsessebe and the caama. Herr Matchie’s Damalis jimeru is not 
clearly separated from the tsessebe. The most characteristic feature of 
this species is the slate-colored markings on the sides of the shoulders 
and flanks, while the general color is brown, fulvous or tawny. 
Of the North African forms we can only mention here Hunter’s 
hartebeest, which has a much shorter face than the typical caama. It 
stands some 4 feet at the withers, and is of a uniform chestnut brown, 
with white tail and belly. A white chevron stretches between the eyes. 
The horns are inclined outwards at the base, and then run vertically 
upwards, the greater part being quite smooth; length round curve, 
26% inches. (The Scientific African, February, 1896.) 
Zoological News.—The material obtained by deep-sea dredging 
in the gulf off the coast of Cape Breton includes many animals 
hitherto considered as exclusively Mediterranean as to habitat. In 
view of the importance of this discovery, M. De Folin (de Biarritz) 
has prepared a catalogue of the species found in the collections, the 
first installment of which is published in the Revue des Sciences Nat. 
de l’ouest, April, 1896.

Fossil Cockroaches.—Mr. 8. H. Scudder’s studies of the Ameri- 
can Fossil Cockroaches have recently been published by the U.S. 
Geological Survey (Bulletin 124). Most of the forms figured and de- 
scribed are from the paleozoic fauna. While, in 1879, only seventeen 
species of cockroaches belonging to this fauna were known, there are 
132 species now described. 
Dr. Packard’s Monograph of Bombycine Moths.—In the 
important memoir recently published by the National. Academy of 
Sciences, Dr. A. S. Packard embodies the results of many years work 
upon the Bombyces. The volume contains about 300 quarto pages 
and 50 plates, many of the latter being beautifully colored. The scope
