464 MARINE BIOLOGY OF THE SUDANESE RED SEA. 
the small ¢ 379 the larger right hand makes an approach to Milne-Edwards’s: 
fig. 7, the lower border being slightly concave near the base of the fingers 
and the fingers not markedly hooked at tips; in the more slender left hand 
of the same specimen the ends of the fingers are strongly curved towards each 
other, which condition occurs also in both hands of all the other examples. 
It will be noted, as pointed out above, that though in the smaller g one 
hand is more massive than the other, yet in the larger ¢ the two hands are 
equally massive.

Remarks. The specimens agree with Alcock’s description of the genus and 
species. Miers’s figure (1884, pl. 48. fig. C) would have given a good idea 
of the present examples if the fringing sete, even of the front, had been 
made longer. Many of the very long fine sets which fringe the front, the 
antero-lateral borders, the chelipeds, and the walking-legs are in the present 
specimens more than one-half as long as the carapace, and give a very 
beautiful appearance to the creatures. 
I give an anterior view of the front with the setee removed, which is. 
“turned down and distinctly arched ”—a character of the genus Litocheira, 
to which Alcock calls attention. 
Miers gives dimensions of his 9 specimen as C.l. 4 mm. and C.b. 5 mm., 
but this may be a slip, as his figure, drawn to scale, gives ratio as 4 to 6. 
De Man (1888, p. 93) cites a ¢ as having Cl. 7-75 and C.b. 1025 mm. 
Alcock givesa 2? as 6X9. The measurements in the present specimens are 
as follows:—

In the ovigerous female 383 the breadth of the frontal margin is 2 mm., 
and a line uniting the external angles of the orbits measures 4°25 mm. 
Both genus and species are new to the Red Sea.
