Family Tiialassinid.e. 
Gebia hirtifrons. White. 
Beak above depressed, with six or seven longitudinal rows of small 
tubercles, furnished at the tip with tufts of hairs ; stomachal region 
smooth ; false natatory appendage large and ciliated. 
Nad. South Seas (Antarctic expedition). 
The only specimen which I have seen appears to be very young, 
as the crust seems hardly formed. It is closely allied to the Gedia 
stellata. 
Family Astacid^. 
Astacus Zealandicus, White. 
Carapace smoothish ; beak as long as the peduncle of the outer 
antennae, wide, depressed, with a slight keel near the base ; the edges 
thickened, and with five or six small denticulations. Hands some- 
what compressed, the outer and inner edges spined, the spines of 
the inner edge the longer ; the hand with many longitudinal rows of 
hairs in tufts ; wrist with three spines on the inner edge, and a 
deepish groove above ; the caudal plates all of a crustaceous sub- 
stance ; the upper side with many small tufts of depressed hairs. 
Had. New Zealand. 
Found by the late Mr. Percy Earl, who collected this and many 
other objects of natural history now in the British Museum. The 
Dendrodlax Earlii, White, a very interesting Lamellicorn Beetle, 
allied to Ryssonotus and Lamprima, but with much of the aspect of 
an Oryctes, was named in compliment to him in the “ Insect Fauna of 
New Zealand,” published in one of the numbers of the ‘ Zoology of 
H.M.SS. Erebus and Terror.’ Much was expected from him ; but he 
was drowned in a lamentable shipwreck olF the Australian coast. 
It is distinct from any species described by Prof. Milne Edwards, 
Dr. Erichson of Berlin, or Mr. Gray in the ‘ Appendix to Eyre’s 
Central Australia,’ published in 1845. 
Family Alpheid^e. 
Alope, White. 
Carapace very wide, dilated on the sides behind, and sinuated in 
the middle. Beak short, serrated above, buried in a deep groove, 
which has a spine on each side in front, almost reaching to the tip 
of the beak. Eyes wdth a thick short peduncle, situated in a hollow 
spine on each side, the outer spine shorter than the inner, which, 
as has been said, is on the side of the beak. 
Inner antennae thick and elongated ; second joint much longer 
than the third, which is slightly cloven at the end and has two ter- 
minal styles, the one very long and cylindrical, the other short and 
compressed. 
Outer antennae situated outside the inner ; the lamellated appen- 
dage elongated, longer than the thickened basal joints, the last of 
which has a tuft of hairs at the end ; the terminal fillet very long,
