7. 
Of three specimens preserved dry from the Durban Museum, 
the largest measured 49 mm. between the lateral spikes of 
the carapace, by a length of 47 mm. The spike on the left 
side measured 14°5mm., that on the right was imperfect. 
A second specimen, also a male, was only slightly smaller. 
The third, a female, measured 42°5 mm. between the spikes, 
with a total breadth of 63 mm., by a length of 40 mm. The 
transversely-grooved ridge or milling, as Alcock appropriately 
calls it, on the outer surface of the movable finger, so con- 
spicuous a feature in the male chela, is entirely wanting in 
the female specimen. The two obliquely-grooved ridges or 
stridulating areas on the inner side of the palm are common 
to both sexes, the external surface of the hand being also 
nearly the same in both. 
For two specimens of the same species, male, from Borneo, 
I am indebted to Dr. Charles Hose, D.Sc., and for a female 
specimen from Singapore, to my nephew, Mr.-C. J. Saunders. 
I had completed the above discussion before remembering 
that Alcock had subjected the genus to a most elaborate revi- 
sion, with the result that he acknowledges five species, M. 
inermis, Miers; M. banksi, Leach ; M. miersii, Henderson ; 
M. victor, Fabricius ; and M. lunaris, Herbst, with a reserve in 
favour of M. planipes, Fabricius, in case Hilgendorf’s identifica- 
tion applies only to Herbst’s second Junaris, and not also to his 
first. That the South African specimens agree with Alcock’s 
description of M. victor is clear, but neither under that heading 
nor any other does Alcock happen to mention either Forskal’s 
Cancer lunaris or Riippell’s Matuta Lessuerv. From Forskal’s 
description it may be worth quoting two of the characters, 
“frontis lobis tribus, medio marginato,” and, following an 
account of the chelz, ‘‘ pedum reliquorum omnium plantae et 
carpi flavi, compresso-dilatati (sic enim commodius remigat 
animal). Whatever may be thought of the claims of Leach’s 
M. banksii and Henderson’s M. miersii, to specific distinction, 
I think it certain that the species recognised by Hilgendorf, 
Alcock and others, as M. victor, Fabr., ought to be called M. 
lunaris (Forskal), and that under no circumstances can Herbst’s 
name be used as author of a valid M. lunaris distinct from 
Forskal’s.
