deeper than the body, and produced posteriorly, so as to cover that of the 
following pair of pereiopoda. The posterior pair of pleopoda are styliform, 
unibranched, the ramus biarticulate. The telson is simple and squami- 
form."

* Coxe of the posterior gnathopoda and the two first pairs of pereiopoda 
much deeper than their respective segments. Superior and inferior antenne 
subequal in length, equal in length to the cephalon and first three segments 
of the pereion ; the peduneles stout, rather shorter than the flagella. An- 
terior gnathopoda small, the propodos subquadrate, the palm nearly 
transverse. Posterior gnathopoda with the propodos large, cordiform ; 
the palm oblique, undefined. Pereiopoda subequal, rather stout. Colour 
yellow with brown markings. Length about j5 in.” 
Hab. Timaru and Lyttelton Harbour. 
Mr. Haswell obtained his specimens at Port Jackson. Mine differ from 
the deséription and figures given by him in some small points so that I am 
rather doubtful whether they are really the same species or not. 
The first pair of gnathopoda has the palm more oblique than shown in 
Mr. Haswell’s figure. In the second gnathopoda the specimens obtained at 
Timaru differ somewhat from those obtained at Lyttelton, though much too 
close in other respects to be considered as distinct species. The Lyttelton 
specimens are nearest to those described by Mr. Haswell. The palm, 
though it can hardly be called defined, yet has two stout sete at the place 
where the end of the finger reaches to, one on each side; on the under-side 
of the propodos towards the base are a few rather long sete, not shown in 
Mr. Haswell’s figure; and in the centre of the palm is a small sharp pro- 
jection. In the Timaru specimens the propodos is much stouter, palm less 
oblique, and without the small projection at its centre. 
In the last three pairs of pleopoda my specimens closely resemble those 
of M. longicornis as figured by Mr. Haswell. In the figure of M. miersii the 
last pair of pleopoda are drawn with two rami, but this must, I suppose, be 
a slip of the artist’s.
