Phalangella phalangea. Gray. 



Character. — Zoarium wholly adnate, suborbicular or reniform, or obsoletely lobate ; 

 tubular cells long, slender, 0"15 mm. in diameter, disposed in more or less regular, 

 uniserial rows radiating from a mesial line. Walls of free portion of zooecia ringed, not 

 punctate. Basal expansion thickly punctate. 



Habitat. — Station 315, lat. 51° 40' S., long. 57° 50' W., 12 fathoms, sand and gravel. 



[British and Irish Seas ; Arctic Sea ; coast of Norway ; South Labrador ; Adriatic, 

 Bay of Naples.] 



Professor Smitt and Mr. Hincks appear to be so convinced that this is the form 

 intended by Fabricius that I have thought it better to adhere to their determination and 

 to adopt his appellation instead of Mr. Couch's. 



One peculiarity as distinguishing this form from the very closely allied Tubulipora 



fimbria, Lamk., consists in the absence, so far as I have observed, of punctation of the 



walls of the tubular or free portion of the zooecia, which in the latter species are 



sparsely punctate up to the border of the orifice, also the punctation of the basal 



expansion in Tubulipora fimbria is rather more sparse, and the spots or pores larger.

Character. — Zoarium adnate, flabelliform, often recurved on the sides. Zooecia 

 decumbent, irregularly disposed or very obscurely serial. Surface of basal expansion 

 and tubes punctate, often transversely rugose. Zooecia about 0"15 to 0"17 mm.
