Parapronoe clausoides, Stebb. (Fig. 165). 



Stebbing, 1888, p. 1529, pi. cxci. 



Walker, 1909, p. 54. 



Stephensen, 1925 a, p. 165 (united with crustulum). 



Occurrence: St. 296. East mid-Atlantic. 3 $? with embryos 17 mm. 



Remarks. Identified with clausoides on account of the very 

 conspicuous serration of the 2nd joint of peraeopod 4, as shown 

 in Stebbing's figure; but this serration is stronger and all the 

 denticles except those on the proximal third of the row point 

 towards the base of the joint ; also on account of the elongate 

 process of the 4th joint of same peraeopod, and the two terminal 

 joints of peraeopod 5 . The sides of the telson, however, are evenly Fig- l6 5- Parapronoe clau- 

 convex as in clausi and crustulum, and the lower margin of the so l ' te ' econ 1 J0in 



. • r 1 ■ ^ f of peraeopod 4, with mar- 



5th joint of gnathopod 1 is smooth. All these characters may • f urther enlarged. 

 later be shown to be subject to variation. 



Distribution. Australia; Indian Ocean.
