be "rounded like that of a Boweröankia". The Farrella atlantica described in the same place 

 has the muscles of a Mimosella and it is indeed identified by Waters with Hippuraria verti- 

 cillata Hincks (non Heller). It appears to me to be clearly distinct from F. atlantica Busk. 



Fam. Buskiidae Hincks.

The diagnosis of the Family given by Hincks runs as follows: — 



"Zooecia contracted below, not continuous with the creeping stolon, with an aperture 

 "on the ventral surface". 

 In the form which I refer doubtfully to Buskia nitens, I have not been able to convince 

 myself of the existence of the "aperture".

Mr Waters (t. cit.) states that B. socialis Hincks possesses a gizzard and that it cannot 

 be included in Buskia (of which the genotype is B. nitens). But if I am right in believing that 

 both B. nitens and B. setigera possess a gizzard, the subdivision of the genus indicated by 

 Waters does not appear necessary.
