BUSKIID^E. 531 



Family V. Buskiidae. 



VKSICVLAKIAD.E (part.), Alder. 



ZOCECIA contracted below, not continuous with the creeping 

 stolon, with an aperture on the ventral surface. 



Genus BUSKIA, Alder. 



Der. Named in honour of Prof. Busk. 

 BUSKIA, Alder, Trana. Tynes. Nat. F. 0. (1857). 



GENERIC CHARACTER. ZCXECIA corneous, flask-shaped, 

 decumbent, adherent for a great part of their length, deve- 

 loped at intervals from a creeping tubular stem ; a mem- 

 branous area on the ventral (or under) side immediately 

 below the orifice. POLYPIDE with a small number of ten- 

 tacles. Gizzard ? 



SEVERAL genera contend for the honour of bearing 

 Mr. Busk's name ; but there seems to be no doubt that 

 Mr. Alder's Buskia was the first in the field. The well- 

 deserved tribute is enhanced in value, coming, as it does, 

 from so accurate and accomplished a student of the Inver- 

 tebrata. 



In this genus there is an " aperture " on the under or 

 ventral side of the zoo3cium, which is covered by a thinner 

 material than that of which the upper portion of the cell 

 is composed. This aperture corresponds with the similar 

 structure which we find in Triticella and Mimosella, and 

 represents the membranous area of the Cheilostomata, 

 on which the oral operculum is placed. It occupies the 

 whole space between the terminal orifice and the point at
