CRUSTACEA 311 
Auckland, Lyttelton, and Chatham Islands. Some of those 
gathered at Auckland (for which I am indebted to Mr. H. Suter) 
had already been labelled Sphwroma chilensis by him. 
The first three joimts of the palp of the maxillipeds are 
produced into lobes on the inner side just as in Exospheroma 
gigas, and the species must therefore be transferred to that 
genus. I postpone a more detailed description of the species. 
On some of the specimens were found individuals of the 
species [ais pubescens (Dana) which is so common as a semi- 
parasite on FE. gigas.

Numerous specimens of various sizes were found on the 
carapaces of nearly all the specimens of Paramithrax longipes 
Thomson, with which it seems to be specially associated (see 
ante p. 289). Other specimens were found on a Voluta shell 
inhabited by the hermit crab Eupagurus rubricatus Henderson. 
The species is common in New Zealand seas, and is also found in 
Australia. 
SCALPELLUM sPINOSUM Annandaie. 
Scalpellum (Smilium) spinosum Annandale, Trans. N.Z. Inst. 
xliii., 1911, p. 164, with figs, 1-4. 
Several specimens from Station 5 forming a fine series 
crowing together in tufts. 
I had described this species as new, but I find that it is the 
same as one recently described by Mr. Annandale in a paper 
read before the Otago Institute, on the 5th July, 1910, the MS.
