Family Thalassinid.e. 

 Gebia HiRTiFiioNS, 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. 



Ilab. 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 Gebia 

 stel/ata.' 



Family Astacid^. 



^_ AsTACus Zealandicus, White. 



BlJCarapace smoothish ; beak as long as the peduncle of the outer 

 ^antenna?, wide, depressed, with a slight keel near the base ; the edges 

 [ thickened, and with five or six small denticulations. Hands some- 

 I 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 

 f deepish groove above ; the caudal plates all of a crustaceous sub- 

 j stance ; the upper side with many small tufts of depressed hairs. 

 Hab. 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 

 I Dendroblax Earlii, White, a very interesting Lamellicorn Beetle, 

 \ allied to Ryssonotus and Lamprbna, but with much of the aspect of 

 'l 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 

 I H.M.SS. Erebus and Terror.' Much was expected from him ; but he 



was drowned in a lamentable shipwreck oiF the Australian coast. 

 It is distinct from any species desci'ibed by Prof, Milne Edwards, 



Dr. Erichson of Berlin, or Mr. Gray in the ' Appendix to Eyre's 



Central Australia,' published in 1845.

Alopb, 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 with a thick short peduncle, situated in a hollow 

 tpine on each side, the outer spine shorter than the inner, which, 

 M has been said, is on the side of the beak. 



Inner antennaj 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
