Subtribe DROMIACEA. 
Family DROMIID ZK. 
Genus Dromipia, Stimpson, 1859, emend. Borradaile, 1903. 
1. Dromipia UNIDENTATA (/tiippell, 1830). See Alcock, 1899 (2), p. 139. 
Dromia wnidentata, Alcock, loc. ert. 
Dromidia unidentata, Nobili, 1906, p. 145. 
Dronudia unidentata, thle, 1913, p. 31. 
Locality. Station VI.,1 ¢ {1] *. 
Remarks. C.1.f 22 mm., C.b. 22 mm., lst W.L.34 mm., 2nd W.L. 32 mm., 
3rd W.L. 20°5 mm., 4th W.L. 25 mm. 
The specimen is of the same order of size as those described by Alcock, 
but his statement regarding the relative lengths of the walking-legs is that 
“the fourth (last) pair of legs are not so very much shorter than either of 
the first two pairs and are very much longer than the third pair.” 
Genus CRYPTODROMIA, Stimpson, 1859. 
bo 
. CRYPTODROMIA HILGENDOREI, de Man, 1887. See Alcock, 1899 (2), p. 145. 
Dronua (Cryptodronia) Hilgendorfi, Alcock, loc. cit. 
Cryptodromia Hilgendorfi, Nobili, 1906, p. 146. 
Cryptodromia hilgendorfi, Ihle, 1913, p. 45. 
Locality. Station X., 1 ? ovig. [2]. 
Remarks. C.J. 12°5 mm., C.b. 12°5 mm. Alcock describes the carapace as 
being longer than broad in two specimens—a male and a female—from the 
Persian Gulf. In the present specimen this is not the case, nor is it so in an 
example from Ceylon (Laurie, 1906, p. 352), where C.b. + C.l.=1:03. The 
two lateral teeth of the front are less prominent in the present example than 
in the one from Ceylon just named. 
My specimens agree with those of Nobili in having the outer orbital angle 
more prominent and sharper than represented in de Man’s figure ; Alcock 
says that this region is not dentiform, it is in the present specimen at least 
sub-dentiform. 
* The collection is housed in the Museum of the Dept. of Zovlogy, University of Liverpool.
