Body cylindrical; cephalon and first segments of pereion confluent;

represented by the branchis attached to their respective segments only; 
three posterior pairs of pereiopoda subequal; first and second pairs of 
pleopoda rudimentary in the male; the rest obsolete. (Spence Bate, Cat. 
Amphip. Crust. Brit. Mus., p. 858.) 
Caprella nove-zealandie, sp. nov. 
Cephalon furnished with a spinous tooth directed forwards; first segment 
of the pereion rather short, second long, third and following gradually 
decreasing ; superior antenne two-fifths the length of animal; flagellum 
with the infero-distal extremity of each articulus produced, but without cilia ; 
inferior antenne not so long as the peduncle of the superior by one joint ; 
second pair of gnathopoda articulating behind the centre of second segment 
of pereion; propodos ovate; palm armed with a prominent posterior tooth, 
against which the closed dactylos impinges, and a smaller but distinct 
anterior tooth (not lobe); dactylos very much curved; three posterior pairs 
of pereiopoda have the anterior margins excavate and ciliate; the parts 
against which the closed dactylos impinges, armed with a strong tooth. 
Length 1 in. 
Hab : Cook Strait. 
This species approaches C. geometrica, Say, (Cat. Amphip. Crust. Brit. 
Mus., p. 857), from which it differs, however, in the form of the spine on the 
cephalon, in the length of the antennæ, and in the articulation and arming 
of the second pair of gnathopoda.
