maras, Luzon (Cuming), and the Mauritius (Lady F. Oole), besides 

 others without special indication of locality. 



In the larger individuals the spines of the lateral margins are 

 more developed, and the orbits more open above than in the specimens 

 described and -well illustrated by A. Milne-Edwards. The Para- 

 mkippa spatulifrons (Micippa spatuUfrons, A. M.-Edw.), to which 

 Mr. HasweU refers specimens from Cape GrenviUe, is principally 

 distinguished by the dilated palms of the chelipedes, with fingers 

 meeting only at tips ; the lateral margins are not armed with 

 prominent spines as in M. superciliosa, HaswelL 



20. Micippa curtispina (HasweU), 



An adult female is in Dr. Coppinger's second collection from 

 Thursday Island, 3-4 fms. (No. 175), and a smaller male from 

 Prince of Wales Channel, 7-9 fms. 



Haswell's types were from Port Denison. 



This species is very distinctly characterized by the form of the 

 rostrum, which is not merely deflexed but curves round so as to be 

 inflexed at the apex ; the lateral subapical lobes of the rostrum, 

 which are. very little prominent and rounded in Mr. Haswell's 

 Agnizes, are obsolete in the specimens I have examined. 



21. Paramicippa spinosa (Stimpson). 



Several specimens are in the collection from Port Jackson, 

 obtained at depths not exceeding 7 fms. (No. 104). There are in 

 the collection of the British Museum specimens from New Zealand 

 and Brisbane "Water, besides others from Port Jackson. It also 

 occurs, according to Mr. HasweU, at Port Stephens. 



The Micippa mpereiliosa of HaswelL (t. c. p. 446, pi. xxvi. fig. 2), 

 from Darnley Island, Torres Straits, is an interesting and apparently 

 very distinct form, intermediate between this species and the Midppa 

 philyra (Herbst). It differs from P. spinosa in the acute lateral spines 

 of the rostrum Sec, and from M. philyra in the compressed and 

 dilated palms of the chelipedes with fingers which, when closed, 

 meet only at the tips, on which account I should be inclined to 

 refer it to the genus Paramicippa.

 localities anticipated by Mr. HasweU.
