380 Mr. E. J. Miers on Ocypoda. 
M. De Man is, I think, right in regarding the Ocypoda 
Orvillet of Guérin (which Mr. Kingsley retains as distinct) as 
a synonym of this species. I may note that the greater length 
of the ocular styles is not exclusively, although generally 
characteristic of the male sex, since I have observed adult 
males from Duke-of-York Island in which they are much 
shorter, projecting little beyond the outer orbital angle. 
In adult male specimens from the Sandwich Islands (W. 
HT, Pease), which otherwise do not differ from the typical O. 
ceratophthalma, the transverse striz on the stridulating-ridges 
of the chelipedes are separated throughout by equal intervals, 
so that the ridge appears to be very evenly but coarsely stri- 
ated throughout its length. 
2. Ocypoda cursor (Linn.). 
Of this species, which has been recorded from various 
Mediterranean localities and from the coast of Senegal, the 
Congo, Acra d’Elmina, and the Cape-Verds, and in which 
the carapace is broadest at the antero-lateral or exterior orbi- 
tal angles, which are acute, the ocular styles short and ter- 
minated by a pencil of hairs, and the stridulating-ridge of the 
larger chelipede very finely striated, there are at present no 
adult examples in the Museum collection. 
In a series of young specimens of small size from Syria 
(Dr. O. Staudinger), which may possibly be immature O. 
cursor, the eyes are distally rounded, without any indications 
of a terminal style, and the sides of the carapace straight for a 
short distance behind the antero-lateral angles, the stridulating- 
ridge is very narrow and indistinct, but finely striated. 
I may reter to Savigny’s figure of this species in his large 
work on Egypt for a representation of the characteristic pecu- 
liarities of the carapace and eyes *. 
The deficiencies of the Museum collection as regards adult 
examples of QO. cursor will doubtless be supplied whenever 
opportunity shall offer for the examination of the large series 
ot ‘Challenger’ Brachyura, at present unpacked and awaiting 
transference to the galleries of the new Natural-History 
Museum, since Mr. Moseley expressly records the occurrence 
of this species (as Ocypoda tppeus) at St. Vincent, Cape- 
Verds t.
