Glorioso Islands. Beach and reef at low water, May 1882 (No. 220);
7-10 fins., sand and mud, May 1882 (No. 219).
Mozambique. Beach, between tide-marks, May 1882 (Nos. 224, 225,
227); specimens found in the interior of Hrt'dacwii-sliells (No. 237).
In the systematic list of the species which follows, 104 species
and varieties are enumerated from the African subregion, besides
13 wbicb were collected at Singapore and are uot included in
this Eeport; of these, 16 species and 6 varieties are described as
new to science. 38 species and varieties are indicated as new to
the African subregion; but several of the new varieties may not
improbably have been already recorded by previous writers under the
typical designation of the species.
Little need be said with regard to the geographical distribution
of the species, since the great majority, except in the groups Oxy-
rhyncha and Oxystomata (which are richest in nndescribed forms),
are common in tbe Indo-Pacific region*, but confined, with few
exceptions, to that area of distribution. Such exceptions are Grapsus
maculatus, Lioloplius planissimus, Alpheus edwardsii, and Gono-
dacU/lus chiragra, which extend into tbe Atlantic region; ^ also
Thalamita integra and Calapipa gallus, var. bicornis (if the distribution
of tbe varietj’ be included in th at of the tjqiical form). I t
is not necessary to repeat here what has been already noted on the
affinity of tbe Crustacean fauna of tbis subregion or district witb
th at of tbe West Indies f.
List o f the Species, shoiving their Geograqjhical Range.
N.B. The species and varieties distinguished by an asterisk are those which
I believe to be now recorded for the first time from the Mascarene subregion
and the Eastern coast of Africa. The term “ Oriental Eegion ” denotes that
the .species ranges from the African coast or islands adjacent eastward at
least to one of the island-groups of the Pacific Ocean. At the end of this
Eeport a table is appended, showing the distribution of the species on the
East-African coast and the islands belonging to the same geographical sub-
region.]

Prof. P. W. Hutton, in a recent article on Zoological Geography, adopts
the terms Province and District for marine geographical divisions in contradistinction
to the terms Eegion and Subregion, which he restricts to the land
divisions {vide ‘ New Zealand Journal of Science,’ i. p. 109, footnote, 1882).
