324 L. R. CRAWSHAY. 



their semi-contracted condition in spirit the largest do not exceed 

 1'5 mm. in height, while the majority are considerably smaller than 

 this. The form of the more extended ones is nearly cylindrical with a 

 width equal to about one-fourth or one-fifth of the height, with the 

 apical portion somewhat claviform and surmounted by a rounded 

 conical hypostome. A short way below the hypostome there is a single 

 row. or, perhaps more correctly, a double row of simple tentacles, which 

 often show a distinct arrangement of large and small ones alternately, 

 the smaller ones apparently arising slightly below the origin of the 

 others. The tentacles number from eight to twelve. There is no 

 gonosome present in the colony. 



EUDEXDEIIDAE. 

 Eudendrium capillare, Alder. 



SmaU colonies at Positions 3, 6, 10, 11, 38, 40, 49, 59, 80. On 



Cellaria and Hydroid stems and Chadoptcrus tubes. 

 Depth, 40-51 fath. 



Eudendrium sp. 



A very small species, much like the preceding, but of rather stouter 

 habit, and perhaps distinct from it, was obtained at Positions 14, 

 32, 40, and 53. On Cellaria and Hydroid stems. 



Depth. 42-46 fath. 



Eudendrium ramosum (Linn). 



Several small colonies at Position 34, and four colonies, from i to 

 1 inch in height, on a fragment of a bivalve shell at Position 56. 

 Depth, 42-49 fath. 



BOUGAIXA^ILLIIDAE. 



Bougainvillia ramosa (van Beneden) ? 



Small branching colonies of a Bougainvillia, probably referable to this 

 species, but with none bearing gonophores, were obtained at 

 Position 5, on Inachus dorsettensis, and at Positions 14, 35, and 59, 

 on Hydroids and Cellaria. 

 Depth, 43-49 fath. 



TUBULAEIIDAE. 

 Tubularia sp; 



A single small Tuhdaria, which was not identified, was taken at 



Position 1. 

 Depth, 40 fath.
