1875.] MR. G. E. DOBSON ON THE GENUS CHALINOLOBUS. 383 
Australia, Tasmania, New Zealand, and Equatorial and Southern 
Africa. 
This genus may be considered intermediate between Vesperugo 
and Miniopterus, though it is evidently more closely allied to the 
former, and may be similarly divided into subgenera. These sub- 
genera, however, similarly artificially based upon the presence or 
absence of the minute first upper premolar, separate the species into 
two very natural groups distinguished by other more important cha- 
racters and inhabiting respectively a great continent. 
Synopsis of Subgenera and Species. 
I. Premolars —, first upper premolar minute; fur generally 
dark, black or dark brown; head and shoulders darker 
than the posterior parts of the body; integuments dark... Chalenolobus. 
Hab. Australia, Tasmania, and New Zealand. 
a. Internal basal lobe of the ear not forming a distinct 
lobule at the base projecting backwards..................+08 C. tuberculatus. 
4, Internal basal lobe forming a distinct lobule at the base 
projecting backwards, 
a. Outer margin of the ear terminating in front in a 
pendent lobule; forearm 1''8 in adults......,........... C. gouldiz. 
5’. Outer margin of the ear terminating in a horizontal 
lobule; forearm 1'°35 in adults ..............-.cseeeseeees C. nigrogriseus. 
II. Premolars => the single upper premolar large, close to the 
canine ; fur generally light grey or cream-colour at the 
extremities ; head and shoulders lighter than the posterior 
parts of the body; integuments white or light brown ... Glauconycieris. 
Hab. Southern and Equatorial Africa. 
e. Internal basal lobe of the ear commencing in a long narrow 
lobule projecting backwards. 
e: A distinct postcalcaneal lobule .......00.....:sceseceeeeeenee G. poensis. 
d'. No postcalcaneal lobule; lower incisors not crowded... G. argentatus. 
d. Internal basal lobe of the ear commencing in a short blunt 
lobule. 
e'. No postcalcaneal lobule; lower incisors crowded ...... G. variegatus. 
In the species included under the first section (subgenus Chalino- 
lobus) the tragus reaches its greatest width above the middle of the 
inner margin, as in Vespervgo noctula; and there is either no 
lobule near the base of the outer margin, or its position is occu- 
pied by a slight convexity. In the species included under the se- 
cond section (subgenus Glauconycteris) there is a distinct, acutely 
pointed, triangular lobule near the base of the outer margin of the 
tragus, which reaches its greatest width about the middle of the inner 
margin. 
CHALINOLOBUS GOULDI. 
' Scotophilus gouldii, Gray, Appendix to Grey’s Journ. of two Expe- 
ditions of Discovery in Australia, p. 405. 
Head short, crown of the head very slightly raised above the face- 
line: muzzle broad, obtuse ; glandular prominences on the sides much 
developed, adding to the breadth of the muzzle in front ; nostrils 
prominent above, separated on each side by a small sulcus from the
