104:2 NOTES ON A FEW AUSTRALIAN EDRIOPHTIIALMATA, 



From what has been already said it will be seen that the 

 genera Aora and Microdeuteropus will have to be combined, I leave 

 this however to be done by some one who may hereafter attempt a 

 re-arrangement of the Amphipoda on a larger scale. 



Protella atjstralis. Haswell. 



Cat. Aust. Crust., p. 311 ; Proc. Linn. Soc, N. S. Wales, IV., 

 p. 276, PI. XII., fig. 4. 



A single specimen from Sydney Harbour. According to Haswell 

 the form of the posterior gnathopoda varies ; in my specimen the 

 palm has only one tooth, viz., the defining one at the proximal end. 

 The antennae are scarcely so long relatively to the length of the 

 body as given in the description, the upper one has the flagellum 

 nearly as long as the peduncle and the lower ono is slightly longer 

 than the pedtmcle of upper ; the sj)ecimen, however, appears to 

 be a young one and the relative lengths of the antennae and of the 

 difierent joints appears to vary considerably at the different stages 

 of growth in these animals. 



PiiiLOUGRiA marina. S. Chilton. 



I have already described this species, which was taken at Coogee 

 Bay, in a paper communicated to the Linnean Society, N. S. W., 

 on June 25th, 1884. 



Paratanais ignotus. N. sp. 

 [Plate XLVIL, fig. 2 ; XLVL, fig. 3.] 



Cephalon narrowing anteriorly, slightly pointed between the 

 bases of the uppper antennae which are closely approximated. 

 Antennae short, inner pair stout, the basal segment about three 

 times as long as the second, third smaller and more slender than the 

 second, succeeded at the end by a minute joint which bears a small 

 tuft of long setae. Outer antennae nearly as long as the inner, but 

 more slender, first three joints of the peduncle short ; the second 

 bearing at distal end two stout spines one above and one below, 

 the third bearing a stout spine on upper surface at distal end, lust 

 joint smaller than the penultimate, which is as long as the two 

 preceding taken together, and having at the end a small tuft of 

 long setae. First gnathopoda stout, propodos curved, dactylos with
