In certain remarks (‘ Chal. Rep.’ p. 36) Mr. Busk justifies his adop- 
tion of these specific names, to the whole of which I direct the attention 
of the student, as without the plates and diagnoses it would be useless"to 
quote extracts. 
Genus 17. Bugula, Oken. 
This genus has a number of synonyms, for which see Hincks, ‘ Brit. 
Mar. Polyzoa’; but one peculiar form, not given by Mr. Hincks, is the 
subject of a rather elaborate paper by Mr. Busk which will be referred to 
further on.

These are the whole of the British forms given by Mr. Hincks, some 
of which have a very wide range around our coast; and the geographical 
range is also very varied. In Mr. Waters’s ‘Bry. Bay of Naples’ ‘he 
records as Mediterranean forms— 
1. Bugula avicularia, Pallas = B. turbinata, Hincks.

fastigiata=B. plumosa, Pallas. In 8. O. Ridley’s paper 
on the Polyzoa of the ‘ Alert’ Expedition (‘ Ann. Mag. 
Nat. Hist.’ 1881), the author quotes— 
B. Murrayana, var. fruticosa, Packard, as one of the forms 
of the Arctic circle. Mr. Busk (Polyzoa of the North 
Polar Expedition, ‘Linn. Soc. Jour. Zoology,’ vol. xv.) 
gives the two forms as distinct.
