I!V CHARLES CHILTON, M.A. 10-43 



inner margin smooth, fixed finger with a slightly convex inner 

 margin furnished with a few strong hairs and two or three rounded 

 projections. Second thoracic leg long and slender, ischios very 

 short, dactylos very slender, slightly longer than the propodos. 

 Third and fourth thoracic legs similar, stouter than the second, 

 basos long and stout, ischios very short, meros and carpus < qual in 

 length and stouter but shorter than the propodos, the last three 

 joints bearing stout spines at their distal ends, inner margin of 

 dactylos smooth. Fifth, sixth and seventh thoracic legs similar to 

 one another and differing slightly from the third and fourth, basos 

 very stout, greatest width half its length, meros and carpus sub- 

 equal shorter and stouter than the propodos, all three bearing at 

 distal ends stout slightly curved spines, those on propodos at base 

 of dactylos are serrated and are more numerous in the seventh 

 thoracic leg than in preceding, dactylos curved, slender, inner 

 margin smooth? Extremity of abdomen truncate but having in 

 centre a small triangular, apparently membranaceous projection 

 which bears two short seta?. Caudal appendages short, inner 

 branch with 5-7 joiuts, outer very short, one-jointed. 



This species appears to resemble Paratanias tenuis, G-. M 

 Thomson somewhat closely, but I have only one very small 

 specimen of this latter species and I do not feel inclined to base 

 any very positive assertion on the resemblance of the descriptions 

 alone. It is very closely related to P. tenuicornis, Haswell, but 

 differs in the presence of the spines on the under surface of the 

 peduncle of the lower antennae and other minor points 



The following five species I have also taken in New Zealand : — 



PROBOLIUM (1) MIERSII. 



Montagua MIERSII. Haswell. 



Cat. Aust. Crust,, p. 226. 



Specimens doubtfully referred to this species have been taken 

 at Timaru and at Lyttelton. See Transactions New Zealand 

 Institute, Vol. XV., p. 72. 



(1). The Rev. T. R. R. Stebbing informs me that the genus Montagua 

 has given place to Probolium, Costa. See also Bate's and Westwood s 

 British Sessile-eyed Crustacea. (Appendix), Vol. II., p. 527.
