DISCOVERY REPORTS 



Gnathopods i and 2, 5th joint triangular, distally widened, 6th with ill-defined palm. 

 Peraeopod 5 longer than, or at least as long as, peraeopod 4. Telson apically incised or 

 deeply notched. 



Remarks. The diagnosis of Epimeriopsis (Barnard, 193 1 , p. 428) based on a specimen 

 erroneously identified as anstralis, Chilton, together with the designation of this 

 species as the genotype, constitutes a composite diagnosis, and the name is therefore 

 void ab initio. 



Eclysis similis, n.sp. (Fig. 112).

Description. Agreeing in general with Chilton's description and figure of A . anstralis, 

 1 91 2, but with the following differences and additions. 



Head with antero-inferior corner produced in a short subacute point. Side-plate 1 

 widening below, lower margin slightly convex, not straight as in Chilton's figure. Side- 

 plate 5, postero-inferior angle rounded as in the 6th side-plate. Dorsal teeth not quite 

 so high as in Chilton's figure ; that on pleon segment 4 more evenly rounded and not 

 so strongly lobed just above the notch. Telson apically incised, lobes subacute, with 

 four denticles (asymmetrical). 



Antenna 1, the teeth on 1st and 2nd joints are all short, not at all prominent, 

 accessory flagellum absent. Epistome and upper lip gibbous, with a low median keel, 

 separated by a groove; upper lip broader than long, apically rounded-truncate.
