2 Mr. C. Chilton on a new Species of 
and of a peculiar shape. As I have an abundance of speci- 
mens, I am able to describe the species in greater detail than 
has been done for some of the others, and also to give pretty 
fully the peculiar characters of each sex. 
Most ot my specimens are from Port Chalmers in Otago 
Harbour. They were taken during low tide on the surface 
of stones and boulders under a mass of decaying Boltenias 
that had been washed up on the beach. ‘They were found in 
great numbers and of all sizes, many of the females bearing 
eggs or young. I have not taken them in the same locality 
either before or since, although I have several times liunted 
over the same spot. Possibly some of them had been washed 
up with the Boltenias and had afterwards increased on the 
beach, though, if so, they must have increased very rapidly, 
as the Boltenias had evidently not been there for more than 
afew days. The specimens of the Munna were so numerous 
on all the stones near that it scarcely seems possible that they 
could all have been washed up with the Boltenias. They 
walked about on the stones somewhat slowly but with perfect 
ease, and seemed quite at home out of the water. The 
excessively long hind legs and the very long antenne, which 
they carried bent back over the body, gave them a very 
spider-like appearance. 
I have since taken a single specimen on sea-weed in a 
rock-pool in Port Chalmers, and another from a rock-pool at 
Brighton, on the east coast of Otago. 
The new species now to be described agrees closely with 
the characters of the genus as they are given by the various 
authors. According to Beddard the affinities of Munna are 
with Pleurogonium and its immediate allies, though it also 
approaches Jwra, Janira, &e. in having biunguiculate thoracic 
appendages *, ‘This affinity with the latter genera is fully 
confirmed by an examination of the mouth-parts and pleopoda 
of the present species, as a comparison of them with those of 
Tanthe speciosa as described by Bovalliust shows that they 
closely conform to the Asellidan type. Bovallius, however, 
does not include Munna in his “ Notes on the Family 
Asellide”’ f. 
I shall first give a short specific diagnosis of the species, 
and afterwards describe some of its parts in greater detail.
