viridu, Rol. Z. wiss. Zool. xxx. pp, 487-500, pi. xxx. ; reviewed,

Vejdovsky (35), in addition to treating of the characters of the ova, 
describes the structure of the Turbellarium-hke male of Bonellia ; he 
describes a cuticle, which according to Selenka (34) does not really exist ; 
a mouth and an anus ; and a pair of chitinous hooks connected with the 
genital aperture. 
Selenka (34) gives some details as to the structure of the Turbellarium- 
like males of this genus ; the integument consists of a layer of ciliated 
cells, the muscles are arranged in an external circular and an internal 
longitudinal layer ; these are succeeded by parenchymatous connective 
tissue, which forms projecting dissepiments into the ccelom ; there is no 
oral or anal orifice to the enteron ; there are twoinfra-oesophageal ganglia 
and a large oesophageal ring ; the right segmental organ is always the 
smaller ; migratory cells, containing chlorophyll, may be observed in the 
coelom and connective tissue. Four to twelve, and at times as many as 
twenty, males are to be found in each female.
