Mr. G. Busk on three new species of Polyzoa. 85 



Scrupocellaria reptans, in which the peculiar structure of this ap- 

 pendage is well seen.

III. 



The species of Anqumaria about to be described was given to 

 me by Mr j! Quekett of the College of Surgeons, who beheves 

 that it came from Torres Straits. ■ e 



It diS so evidently from the hitherto only known species of 

 J^Ma, that there'can be no doubt of t^- specxfic dist^^^^^ 

 tion but at the same time the distinctive character ot the new 

 spec'ies requires but a very short definition. 



Genus Anguinaria, Lamk. 



Sp. Anguinaria dilatata (Busk). 



A. cellulis apice cyathiformibus, ore magno dilatato suborbicu- 



lari. 



Hah. Torres Strait ? 



In habit this species is rather more robust but m other re- 

 spects veiy nearly corresponds with A. spatulata^^f ^^ m tha 

 pedes, the cells arise from a creepmg, branched, decumbent 

 pKoarium, which is adnate on fucus ; m this case a specie of 

 SS«m. It is rather remarkable that Angmnariaspatulata 

 sWd oc m- in Bass Straits and other parts of the Australian 

 seas and m the South of Africa, as well as m Europe, whilst the 

 presen^species would seem to be much more limited m its range ; 

 the one perhaps requiring a temperate and the other a tropical 

 climate.
