Hah. — I have occasionally dredged this species in the 

 Forth estuary, but it was usually passed over as the male of 

 Dactylopodella flava. 



Genus (48) Idomenella, T. Scott, nov. gen., 1896. 



This genus has a general resemblance to Idomene, Philippi. 



The antennules (anterior antennse) short, six- or seven- 

 jointed. 



Posterior antennae tolerably well developed, and composed 

 of two joints. 



Mandibles, with masticatory edge, moderately broad, and 

 armed with several stout but irregular teeth. Mandible- 

 palp well developed, and furnished with two uniarticulate 

 branches of moderate size, the outer one wanting the strong 

 spines that appear to be characteristic of species belonging 

 to Idomene.
