be identical with Amphithoe norvegicus of Rathke. The 
latter has the upper antenne only half as long as the 
lower, whereas I have never seen a specimen in which 
they were not almost exactly equal as shown by Boeck. 
Rathke’s other characters also are scarcely sufficient to 
connect them.

the above species is great (see Stebbing, ‘‘Challenger”’ 
Report, p. 542). As this author remarks,+ his A. zam- 
boange from the Philippine Islands approaches closely 
to A. carinatus, Bruz. Two of the specimens from Port 
Erin agree so closely with the admirable drawings of 
A. zamboange that the two forms can hardly be regarded 
as other than local varieties. |
