 but must rest myself for a month to come on board the Beacon."

Ninth Annual Report of the Royal Cornwall Polytechnic Society. 



Amongst other valuable matter the present report contains an es- 

 say on the Zoophytes of the coast of Cornwall, by Mr. Couch, for which 

 the first silver medal of the Society was adjudged. We noticed among 

 other rare and local species there enumerated, the following : Sertu- 

 laria Ellisii, S. nigra and S. pinnata, Plumularia pennatula, P. Catha- 

 rina and P. myriophyllum, Caryophyllia Smithii, Actinia bellis, VaU 

 ckeria uva, Hippothoa lanceolata, Cellepora Skenei, C. lavis and Lepra- 

 lia trispinosa. Lepralia hyalina is placed amongst the Tubuliporidce, 

 whereas there can be no question of its really belonging to the genus 

 Lepralia of Johnston, as proved by the presence of opercula upon 

 some of the cells. In addition to many rare species, we find also de- 

 scriptions of some new ones, the characters of which we here subjoin. 



Trailing Coral. — Tubulipora trahens. 



Spec. Char. " Polypidom calcareous, creeping, adherent through- 

 out, irregularly and sparingly branched, narrow, with one or two 

 rows of tubes projecting from the upper surface. 



Hdb. " On stones and shells from deep water, not uncommon : 

 Polperro. 



" The polypidom varies from a quarter to one inch in length, but 

 is very narrow and slender. The tubes are commonly single, but 

 sometimes are in pairs and project considerably; sometimes in a 

 straight and sometimes in a waved manner. When the tubes are in 

 pairs they are always close together, but each pair are distant from 

 each other in the lengthways of the polypidom. I am unable to re- 

 fer this to any described species." 



Tubulipora dejlexa. 



Spec. Char. " Polypidom erect, cylindrical, with waved tubes pro- 

 jecting from all parts. 



Hab. "On shells from deep water, common : Polperro, Mevagissey 

 Bay, and off the Deadman Point. 



" This species is very common; it varies in height from one quarter 

 to half an inch ; it is calcareous, white, cylindrical, with sometimes 

 an enlarged globular head. The tubes arise from all parts of the 

 polypidom, and greatly project in a waved form ; they are shorter 

 above than below, and their apertures are even and unarmed. The 

 base is slightly spreading, and of a darker colour than the upper 

 portions. I have been unable to identify this with any described 

 species." 



Tubulipora Fungia. 



Spec. Char. " Polypidom pedunculated, the upper portion expanded
