GLAUCONYOTERIS.

A bone in the penis. 
This species, under the name of Vesperugo temmincJcii, has been recorded from 
Bagamoyo, Lake Albert Nyanza, Galabat (eastern confines of Abyssinia), Sennaar, 
Khartum, and northwards to Berber and Dongola, and now at Luxor. 
P. rueppelli is closely allied to P. pulcher, Dobson, from Zanzibar, but it is 
distinguished from it by its shorter and somewhat differently shaped ears, longer 
forearm, by the much feebler papillation of the posterior border of the interfemoral 
membrane, and by its less numerous caudal vertebrae. 
The male generative organ of this bat, as in other members of the genus allied to 
it, is remarkable for its great length, as in the present male, which measures 46 mm. 
from snout to vent, this organ is 13 mm. long, while the bone which occupies its 
distal end is 7 mm. in length. It is covered with white hairs directed towards the 
base of the organ. In Dobson’s definition of Pipistrellus a bone is excluded from 
the penis. 
The types of this species, seven in number, were obtained by Riippell in the palm^ 
groves and gardens of Dongola. The specimen here described was caught in the hotel 
belonging to Messrs. Cook & Sons at Luxor, situated in a well-wooded garden, 
consisting chiefly of date-palms. 
GLAUCONYCTERIS. 
Glauconycteris, Dobson, Proc. Zool. Soc. 1875, p. 383. 
The species of this genus are mostly remarkable for having the veins and lines on 
the flying-membranes of a different colour from the main part of the wings, and 
for the extremely short and broad facial portion, of the skull. 
One species, G. floweri, de Winton has lately been recorded from the White Nile, 
one specimen being taken at Abu Zeit by Capt. Stanley Flower and a second at Wad 
Mariun by Mr. H. F. Witherby. 
Messrs. Rothschild and Wollaston also obtained specimens of this bat at Shendi. 
In the ‘ Novitates Zoologicae,’ vol. viii. 1901, p. 397, the following field-note is 
published:—“ Common at Shendi, but hard to procure. This bat hides by day 
in the acacia thickets low down near the roots of the trees. At dusk it crawls up 
the branches and takes flight, uttering a very characteristic squeak, which it continues 
to make on the wing. Its very low flight and habit of frequenting the dense and 
thorny acacia bushes make this bat a difficult species to collect.” 
Ihis new form is remarkable for the shagreening of the skin of the forearms, legs, 
and tail.—W. E. de W.
