Notes on Certain Species. 
1. Schizophrys aspera. — One specimen is the var. spinifrons 
of A. M. -Edwards. 
2. Paciiygrapsus transversus, Gribbes, appears to be merely 
a variety of Metopograpsus messor. 
3. Porcellana (P Petrolisthes) corallicola, Ilasw., var. — 
The single small specimen differs so much from the typical 
form in the sculpturing of the wrist and hand of the larger cheli- 
pede, that it is a question whether it ought to be referred to this 
species. The wrist has two rounded longitudinal ridges or 
carinae. The upper surface of the hand is divided longitudinally 
into two unequal parts by a similar ridge, the space on each 
side of which is covered with tubercles. The fingers have a 
similar ridge on the outer surface. In the specimen in the 
British Museum from Queensland the central line of tubercles 
on the band shows a tendency to fuse into a carina. 
4. Diogenes avarus, Heller, var. — I have some hesitation 
in referring the single specimen in the collection to this species, 
with which, however, it agrees except in having the margin or' 
the carapace armed with three small teeth immediately beneath 
the upper external angle. The hand of the large chelipede is 
obsoletely costate externally, but is more robust than in Heller’s 
figure, resembling ratber in this respect D. granulatus, Miers 
(Ann. & Mag. Nat. Hist. ser. 5, vol. v. p. 373, note). (Plate 
VIII. figs. 6, 7.) 
In addition to the Podophthalmia thei'e were a few Isopoda 
not yet examined, and a new Amphipod, Byllis kallarthrus, 
Stebbing, described by the Rev. T. R. It. Stebbing, in Proc.Zool. 
Soc. Jan. 19, 1886.
