462 MARINE BIOLOGY OF THE SUDANESE RED SEA. 
changes during growth indicated by the above table; but specimens 359— 
365 of the present collection have also a naked hand. (As the specimens 
happen to make a convenient series in regard to size I have used them for 
the table above).

Remarks. 9% ovig. 367 has C.1. 14°5 mm., greatest C.b., a line joining points 
of union of antero-lateral and postero-lateral borders, 17°5 mm., Chil. 
28 mm., merus |. measured from most proximal to most distal point of lower 
surface 9 mm.; C.b. across region of outer orbital teeth 15 mm.,so that the 
antero-lateral borders, which are a little convex, slope inwards anteriorly. 
The outer angle of the orbit is pointed. The inner angle of the lower margin 
of the orbit bearsasharp tooth. The boundary between the antero-lateral and 
postero-lateral borders of the carapace is marked by a blunt tubercle. The 
inner angle of the wrist bears a blunt pointed tubercle in place of a spine. 
There are 118 red spots visible in a dorsal view of the carapace, a few of 
them tending to run together in pairs on the lateral portions of the gastric 
regions. 
Specimen ¢ 366 is small, C.l. 5 mm., C.b. measured by a line joining 
points of union of antero-lateral and postero-lateral borders 6 mm. ; a line 
uniting the outer orbital teeth 6°25 mm. It differs from the 9 ovig. 567 in 
(a) the sharp spiniform character of the denticles marking the outer angle of 
the orbit, the inner angle of the lower margin of the orbit, the boundary 
between the antero-lateral and the postero-lateral borders of the carapace, 
the inner border of the arm and the inner border of the wrist ; (}) the almost 
straight character of the frontal border, the teeth being very little marked ; 
(c) the antero-lateral borders of the carapace slope a little outward anteriorly ; 
(d) the number of red spots visible cn the carapace in dorsal view is small, 
namely, twenty-eight. 
The points mentioned above in regard to the small g are probably marks 
of youth. The specimen bears a close resemblance to a 2 of the same 
size and a rather larger ¢ (C.l. 7 mm.), both from Ceylon, which I have 
before me (Laurie, loc. cit.). The Ceylon 8, however, is somewhat inter- 
mediate in the character of its front between the two present specimens and -
