 Hab. Seas of Europe (ubique). 



2. HIPPOTHOA DIVARICATA. PI. XVIII. figs. 3, 4. 



Cells remote, ovate lanceolate or fusiform; subcarinate in 

 front ; aperture small, with a notch in the lower margin. Ovi- 

 cells small, superior, galeriform; branches given off at right 

 angles, and usually in opposite pairs.

 Catenicella divaricata, Blainv. D. S. N. 1830, Ix. 427 ; Man. Act. 

 Hippothoa lanceolata. Gray, Zool. Misc. 35; Hassall, Ann. 4"

Corn. Faun. iii. 102. pi. 18. fig. 6. 

 Hab. Britain. Seas of Europe. 



3. HIPPOTHOA PATAGONICA. PL XVII. fig. 1. 



Cells oval, irregularly attenuated downwards, irregularly an- 

 nulate, thick ; opening small, with a notch on the lower lip, 



Hab. Coasts of Patagonia, Falkland Islands, Darwin. 



The difference between this and the preceding one is hardly 

 greater than what occurs in many of the Polyzoa under different 

 circumstances of age and situation ; but upon comparison of the 

 oldest cells and the most thickened I have been able to meet with 

 in Hipp, divaricata, I am satisfied that the distinction between that 

 species and the present is a good one. 



3. ^TEA. 



Cells tubular, erect, scattered, rising from a creeping fistular 

 fibre adnate to a foreign base. Aperture terminal or subterminal.

Anguinaria, Lamk. 1812 (no char.); Johnst. Br. Zooph. ed. 2. 292. 

 Falcaria ft Oken, Lehrb. Nat. 91, 1815. 



The name Anguinaria appears on the plates devoted to the spe- 

 cies of this genus, but subsequent consideration having shown the 

 justice of recurring to Lamouroux's appellation, his term has been 

 adopted in the text.
