Camptonyx^ g. n. [pre-occupied in the Crustacea by Heller, 1861]. 
Corpus cylindraceum, trunco et cauda non bene disjunctis; antennse 
superiores circiter octoarticulatse, valde setosae ; inferiores appendice bi- 
articulata; palpus mandibulae biarticulatus, ramo accessorio uno ; pes 
maxillaris subcheliformis, ungue gracili et debili ; pedes lmi-4ti parium 
solummodo natatorii, omnes ramo exteriore triarticulato, duo priora 
paria ramo interiore biarticulato eodemque parium ambo posteriorum 
triarticulato ; pedes 5ti paris valde rudimentarii, tantummodo tuberculo 
in aculeum producto confecti. C. parenti, sp. n., Lilljeborg, (Efv. Ak.

Peltidiidj:. 
Hersilia apodiformis (Philippi, 1839) = Clausidium testudo (Koss- 
mann, 1874) described, and its systematic aflSnities discussed ; by the 
shape of the body, the structure of the skin and the conformation of the 
legs it is nearly allied to Peltidium, from which it differs in its parasi- 
tical life and consequent reduction of the buccal organs and inequality 
of sexes. C. Claus, Z. wiss. Zool. xv. pp. 327-334, pi. xxii. 
Notodelphyidjc. 
This family may be subdivided as follows: — 
1. Sub-fam. Notodelphyince, body flat, upper antennae 10-16 jointed, in 
the male fit for clasping, as in Cyclops : Notodelphys (Alim.). 
2. Sub-fam. Doropygime, body laterally compressed, upper antennae 
short, with fewer, often 8, joints, not clasping ; furca clasping : 
Doropygus (Thorell), Notopterophorus (Costa), Goniodelphys, 
Gunentopherus (Costa), and Botachus (Thorell). 
3. Sub-fam. Ascidicolince ; matrical duplicature of the fifth thoracic 
segment separated into two leaves : Ascidicola (Thorell).
