outer and inner margins of both rami spinulose, inner margin of inner 

 ramus with some plumose setae in addition. 



Side-plates and postero-lateral angles of pleoii segments 1-3 as in 

 E. chelatus Norman (see Sars, I.e. pi. 40, fig. 1). 



Telson as in Chevreux's figure but with 2 spinules on each apex. 



Lemjtli : 17 mm. 



Colour : In spirit, yellowish white. 



Locality : Cape Point NE. by E. -} E., distant 38 miles. 755 fathoms, 

 1 ? t?. s.s. " Pieter Faure." 23/6/03. (S.A.M. No. A129.) 



Geogr. Distribution: Gulf of Gascony, 1453 metres (Chevreux). 



The main differences between this and the northern form are : the 

 larger size, the number of flagellar joints in 1st and 2nd antennae, the 

 relative lengths of 4th and 5th joints of peduncle of 2nd antennae, 

 the shape of the palp of 1st maxilla and the palm of 2nd guathopod. 

 As regards the last two features, Chevreux's figures are not as clear as 

 could be desired for purposes of an exact comparison. The other 

 features cannot be deemed of specific value. 



PAKAVALETTIA n. g. 



Body not compressed. Side-plates not large, 4th only slightly 

 emarginate behind. Mandible short and broad, cutting-edge obscurely 

 dentate, palp central. Inner plate of maxilliped with 4 apical 

 teeth, outer plate with 2 spine-teeth on inner apex, palp 4-jointed. 

 First gnathopod fairly stout, strongly chelate. Second gnathopod 

 elongate, slender, chelate. Third to fifth peraeopods with 2nd joint 

 moderately expanded. Uropod 3 with 2-jointed outer ramus only. 

 Telson ovate, entire. 



This genus is near to Valettla Stebbing in having a dentate cutting- 

 edge to the mandible, but is distinguished by the chelate 1st and 2nd 

 gnathopods, uniramous 3rd uropod and entire telsou. These last two 

 features it possesses in common with Onesimoides Stebbing, from 

 which, however, the chelate 1st gnathopod separates it. 



Valettiop*i>* Holmes, 1908, appears to differ very little from ralrttl.t. 



PAKA.VALETTIA CHELATA n. sp. 

 (Plate XXVI. Figs. 2-3.) 



Body rounded dorsally. Antero-lateral angles of head obtuse. Eyes 

 not discernible. Side-plate 1 oblong, not narrowed below, smaller 

 than 2, 2-4 subequal, subquadrate, inferior margin rounded, 5 twice
