took it by means of the surface-net. I am unable 
to find any characters which distinctly separate 
Dactylopus cinctus, Claus, from robust forms of 
D. Stromu, and have frequently seen specimens 
which, so far as I can ascertain, might be referred 
equally well either to one species or the other. | 
T am disposed to think that a form described by me 
some years ago, under the specific name ‘‘ Normant,” 
may very probably belong to D. Stromwu. For the 
present, at any rate, it seems best to withdraw the 
name, which can be re-established should further 
research prove the species to be well founded. The 
following is the description of D. Normani :* 
“Closely approaching D. tesboides, from which it 
differs, however, in the following particulars :—The 
superior antenne are 8-jointed, and not so densely 
setose, the proportionate lengths of the various joints 
being as follows: 
& 
The secondary branch of the lower antenne bi-articu- 
late, each joint bearing two moderately long sete. 
Lower foot-jaw (gnathopod) simply chelate, the inner 
margin of the hand fringed with short sete. Longer 
branch of the first foot slender, bearing almost at the 
extremity of the outer margin a short ciliated seta. 
Fifth pair of feet large, outer branch subovate, bearing 
three long seta, one at the apex, one on each lateral 
margin, and three shorter ones on the outer margin
