deeper than the body, and produced posteriorly, so as to cover that of the 



following pair of pereiopoda. The posterior pair of pleopoda are styliforni, 



unihranched, the ramus Inarticulate. The telson is simple and squarni- 



form." 



Montagu ana miersii ?

 pi. XXIV., fig. 4, and Cat. Australian Crust., p. 226.) 



" Coxre of the posterior gnathopoda and the two first pairs of pereiopoda 

 much deeper than their respective segments. Superior and inferior antennas 

 subequal in length, equal in length to the cephalon and first three segments 

 of the pereion ; the peduncles 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 -^in." 



Hab. Timaru and Lyttelton Harbour. 



Mr. Haswell obtained his specimens at Port Jackson. Mine differ from 

 the description 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 ohtained 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 setse 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 setas, 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.

" Body broad. Pereion and pleon of equal length. Coxas of gnatho- 

 poda very small. Coxaa of the first and second pairs of pereiopoda enor- 

 mously developed, and cemented together to form broad and deep lateral 

 shields, concealing almost entirely the gnathopoda and pereiopoda, and 

 extending forwards to the sides of the cephalon, and backwards as far as
