OF THE ' SOITTHERlSr CROSS ' EXPEDITION. 51 



expanded at the proximal end ; palm oblique. Side-plates 

 narrowing downwards, with a small tooth at the posterior angle. 



Second gnathopods : the propodos fully as wide as the carpus, 

 upper and lower margins subparallel, the latter not produced. 

 Side-plates slightly expanded below, with a small tooth at the 

 posterior angle, not shown in the figure. 



Pirst and second perseopods rather slender, the 5th joint 

 spinous on the anterior margin. 



Third perseopods : the 1st joint M'ide but narrower than the 

 side-plate and about as deep ; the 3rd joint considerably expanded 

 behind ; the 4th joint wider than the 5th, and also than the 4th 

 joint in the last pair of perseopods. 



Fourth and fifth perseopods : the 1st joint larger than in the 

 3rd perseopods : the 3rd joint less expanded ; the 1st joint in 

 the last three pair of legs is serrate behind, and all the joints are 

 more or less spinous. 



Uropods : the 1st pair extend beyond the 2nd, the inner 

 ramus shorter than the outer : the rami of the 2nd and 3rd pairs 

 are subequal, in tlie last both rami are spinous and setose on the 

 inner margin, and the outer has two large spines on its outer 

 margin, the inner a little the shorter. 



Telson long, cleft almost to its base, with 3 or 4 spines on 

 each margin and the usual single apical spine. 



Length about 15 mm. 



T. Murrayi belongs to a group of northern species with the 

 hind margin of the 3rd metasome-segment almost or quite 

 straight, and with a triangular carina on the 1st urosome-segment. 

 Of these, T. Horingii, Boeck, and T. angulata, Gr. 0. Sars, differ in 

 the form of the lateral angle of the head ; while T. covipressa, 

 Or. 0. Sars, differs in the much compressed body, in the form of 

 the propodos of the 2nd gnathopod, and the relative proportions 

 of this and the 1st gnathopod.
