R. DOUGLAS LAURIE—BRACHYURBA. 457 
It will be noted that the number of teeth is very variable. The larger 
teeth are of an order of size easily made out under a hand lens which 
magnifies 6 diameters. 
To sum up :—The specimens fall under C. spinipes. C. wood-masoni has, 
however, a frontal condition difficult to distinguish from that of C. spinipes. 
The presence of the minute accessory spinule in specimen 226 and the 
character of the right chela in specimen 218 should be noted as some 
approach to C. wood-masoni. One could hardly perhaps unite the two species 
on the data supplied by the present specimens, but on the other hand Nobili’s 
remark is to be kept in mind to the effect that examples examined by him 
throw grave doubt upon their specific distinction.

Localities. Station 1. J, 1 ¢ [227]; Station V. H, 1 g$ [228], 3 2 [229— 
931]; Station VIII. D, 4 ¢ [232-235], 2 9 [236, 237]. 
Remarks. & 227 is apparently adult, C.l. 18 mm., C.b. 19 mm.; all the 
others are small, C.l. from 3°25 to 6 mm. 
The small ? specimens 229 and 236, with C.1. 6 and 5°5 mm. respectively, 
though not ovigerous, appear to be adult, whereas another specimen with 
C.l. only 4 mm. is immature. 
- The frontal breadth of the large specimens agrees with Alcock’s descrip- 
tion, ‘2 the greatest breadth of the carapace,” if it be taken to include the 
inner supraorbital angles ; but if the latter be excluded then the front is only 
-33 the greatest breadth of the carapace. 
In all the specimens the granules lose their sharpish character on the 
lower part of the outer surface of the larger hand, becoming here more 
rounded and pearl-like. 
In the large specimen 227 the granules on the upper part of the outer 
surface of the wrist and hand are sharpish conical; in the other and smaller 
specimens the granules in this position are sharper, and in some specimens 
some of them are almost spines. 
The areolation of the carapace is less clearly seen in the small specimens. 
The present examples do not include any having the brown fingers of var. 
melanodactylus, de Haan, which variety is, however, also recorded from the 
Red Sea. For the synonomy of var. melanodactylus, see Alcock, 1898, p. 174 ;
