Spengel (38) states that the ovary of Bonellia is placed in the ventral 
portion of the body, and is connected with the ventral blood vessel, the 
peritoneal investment of which is concerned in the formation of the ova ; 
an amphigastrula is noted, for the first time, among the Gephyrea. The 
males form green scales on the proboscis of the female, to which they are 
very firmly attached, in large numbers; they are altogether larval in cha- 
racter, save that they have lost the two bands of cilia ; they are essentially 
Gephyrean in the important points of their organization — development, 
after the larval stages, being directed only to the maturation of the male 
organs. 
In (39), Spengel gives a succinct account of the results of his researches.
