R. DOUGLAS LAURIE—BRACHYURA. 419 
Calappa gallus (Herbst), Grapsus grapsus (Linn.), Planes minutus (Linn.), 
Perenon planissmum (Herbst), Metopograpsus messor (Forsk.), Plagusia 
depressa (Herbst), and Thalamita integra, Dana, of which the first four are 
of little or no account, owing to their exceptionally wide distribution, and 
the last two are varietally distinct. 
To save frequent repetition, I give here a list of stations from which the 
present collection was made, the latitudes of which I have estimated 
approximately. 
Crossland’s maps, published in the present volume of this Journal, 
pages 6 and 15, and Plates 28, 29, and 30, should be consulted.

docks for several years. 26 Dec., 1904.

H. Suez Bay. Trawled in 5 fathoms, from mud bottom, among 
sponges. 
I. Suez Bay. From a red sponge taken from mud bottom in

J. Suez. From among coral. 
K. Suez. Washed by fresh water from two coral colonies. 
L. Ktuleh coral shoals, Suez Bay. Large areas covered by Chama 
and an Ostreid. In 1-3 fathoms. 
II. Mersa Wadi Lehama, Egyptian coast. Lat. 24° 43’ N, 
III. Cape Elba, the northern frontier of Sudan coast. Lat. 22° N.

A. Washed from nullipore and branched coral from the reef off Beacon 
Island. Lat. 20° 55’ N. 26 April, 1905. There were many 
Polycheta and Decapoda, comparatively few Amphipoda, and some 
Hechinodermata in the same washings. 
B. Just west of Beacon Island. Lat. 20° 55'!N. Washed from nulli- 
pore dredged in 3-5 fathoms, 26 April, 1905. In the same 
washings were many Decapoda and Polycheta, especially the
