3rd pleon segment (I have not seen Bonnier’s figures). It is, how- 
ever, more feebly carinate and the apices of the telson are not 
dehiscent. The 2nd joint of the 5th peraeopod is very similar to that 
of R. provvma Chevreux. The perfectly entire postero-lateral margin 
of the 3rd pleon segment is quite exceptional in the genus, although 
R. gracilis has “only 8 scarcely visible denticles”’ ; to this feature 
the specific name refers.

The reasons for the above synonymy are as follows: 
In 1912 Chilton (Lc. p. 498) described a local variety of Paramoera 
austrina (Bate) from Saldanha Bay, South Africa, whose chief pecu- 
liarity is the absence of setae and the greater number of apical
