Plialangella 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 zocecia ringed, not 
punctate. Basal expansion thickly punctate. 
Habitat. — Station 315, lat. 51° 40' S., long. 57 50' W., 12 fathoms, sand and gravel.

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 zocecia, which in the latter species are 
sparsely punctate up to the border of the orifice, also the punctation of the basal 
expansion in Tubulipora fimbi'ia is rather more sparse, and the spots or pores larger.
