Thomson, of Dunedin, in "Trans. Lin. Soc., 2nd series, vol. 
vio рош. 
The present species differs from А. palpalis mainly in its 
smaller size, its non-expanded carapace, its less robust third 
maxillipeds, in the less divided state of the second pereiopods 
—except the carpus—and in many other minor particulars. 
I am not aware of there being known any other species of 
this genus, so I take the liberty of slightly modifying Mr. 
Thomson’s presentation to include the present species. 
Tribe, CARIDEA. 
Family, HIPPOLYTIDA, 
Genus, Alope, White, 1847. 
Carapace smooth, with supra-orbital spines and suborbital 
teeth. 
Rostrum short, armed with teeth above and springing trom

First antenna short, with two flagella. 
Second antenna with large scale (scaphocerite) and long 
flagellum.

and three jointed palpi. 
First maxilla two or three branched. 
Second maxilla three branched with wide mastigobranch:al 
plate. 
First maxilliped with two lobed mastigobranchia. 
Second maxilliped with short podobranchial plume. 
Third maxilliped very long and pediform, without bran- 
chia. 
First pereiopod strong, chela well developed. 
Second pereiopod slender, long, minutely chelate, carpus 
seven-jointed. 
Telson moderately narrow. 
Third to fifth pereiopods with two clawed dactyli.

Alope australis, ». sp. Pl. xxx., figs. 1-7. 
Body smooth, white, with many very small red spots. 
short and robust. Carapace; not carinated dorsally or 
swollen, but slightly narrowing anteriorly. The two long, 
supra-orbital spines are connected dorsally by a U-shaped 
ridge, in the fork of which is a small, broad-based spine, 
and immediately in front of this spine in a depression arises 
ridge, in the fork of which is a small, broad-based spine,
