BoPYRlDiE. 
General remarks on the biology and development of the known genera, 
and list of the authors ; P. Fraisse, Arb. Inst. Wiirzb. iv. pp. 404-437. 
Entoniscus cavolinii, sp. n. (known to Cavolini in 1787), in the visceral 
cavity of Grapsus marmoratus (F.) and Carcinus mcenas (L.), Naples. 
The first larval stage is provided with two pairs of antennse (the pos- 
terior very long), six pairs of thoracic feet (the first prehensile), and five 
pairs of natatory abdominal feet ; second larval stage unknown ; adult 
animal wormlike, segmentation obsolete, four pairs of branchial appen- 
dages at the hinder half of the body, cavity of the head, trunk, and 
peculiar lateral lobes filled with eggs. Fraisse, 1. c. pp. 382-403, pis. xx. 
& xxi. 
Cryptoniscus (Buchholz). A monograph, with historical, anatomical, 
and morphological observations. The male is always free, and represents 
the typical form ; the female fixes itself in all species but one on Cir- 
ripeds, chiefly Peltogastridm, and becomes entirely deformed ; copulation 
has been observed. In the second larval stage, the first two pairs are 
very short, prehensile, and the sixth and seventh are different from the 
preceding ; abdominal feet two-branched ; the rectum has a bottle- 
shaped, dark, pigmented dilatation, which exhales a penetrating smell. 
Eleven species are distinguished and described, including as new: — C. 
paguri, Mahon, on Peltogaster rodriguezi, G. macrophthalmus, Naples, on 
P. curvatus (Kossm.), and C. curvatus, Naples, on Sacculina neglecta.
