368 Mr. M. A. C. Hinton on 
for Jan. 15, 1920 (Akad. Wiss. in Wien), that Karny has 
recently reported on a collection of Thysanoptera made by 
Ebner in the Egyptian Sudan in 1914. Hapiothrips jun- 
corum, Bagn. (originally described from Oxford), is recorded 
for the first time from Africa, and five new species are 
described, of which Dolichothrips giraffa and Gynaikothrips 
ebneri wili probably prove to be closely allied to, if not 
identical with, Dolichothrips jeanneli and Gynaikothrips 
obscuripes, described herein. It is impossible to say more 
than this from the brief abstracts of comparisons at my 
disposal.—R. S. B.

1. THe Orter oF LAKE MuTANDA. 
The British Museum is indebted to Captain J. E. Philipps, 
M.C., for a female otter (Lutra maculicollis) which he collected 
at Lake Mutanda, British Ruanda. Several years ago Mr. 
Robin Kemp obtained a young male (B.M. no. 11.12. 3.528) 
from the same lake. These specimens, together with a male 
(B.M. no. 4. 2. 6.54) from Kazinza, Uganda, collected by 
Mr. W. G. Doggett, differ from the various subspecies of 
maculicolli’s, hitherto recognized, by their small size, and 
especially by their small teeth. They evidently should be 
regarded as belonging to a distinct subspecies, which may be 
described as 
Lutra maculicollis mutande, subsp. n. 
Like true maculicollis in outward appearance, but size 
smaller (smallest of the group, so far as is known). 
Skull with brain-case a little more depressed, its height in 
adults equal to 37°4-39 per cent. of the basal length, the 
corresponding percentage in the other subspecies ranging 
between 39°7 and 42:7. Teeth small, as shown by the 
following comparative measurements in millimetres :—
