NEW SPECIES OF HYDROIDS — FRASER 81 



Genus TUBULARIA Linnaeus (in part) 



TUBULARIA CRASSA, new species 

 Plate 14, Figure 5 



Trophosome. — Individual zooids only were obtained: there is 

 nothing to indicate whether they grow in colonies or not ; the pedicels 

 appear to be complete, but they are but little more than 1 cm. in 

 length, which, even in the contracted condition, has a diameter almost 

 equal to the length of the pedicel. There are no annulations, but 

 there is a definite ridge at the base of the proximal tentacles; proximal 

 tentacles long and numerous, 32-36 ; distal tentacles slender, much more 

 numerous. 



Gonosome. — Gonophores grow in rather long, erect racemes when 

 well developed; these racemes are densely crowded so that the body 

 of the hydranth is almost entirely hidden; there are no tentacular 

 processes on the gonophores.

Family CAMPANULARIDAE 

 Genus CAMPANULARIA Lamarck 



? CAMPANULARIA FASCICULATA, new species 

 Plate 15. Figuee 6. 



TrophosoTTie. — Colony 2 cm. in height, with the base of the main 

 stem and some of the lower branches fascicled. The simple branches 

 are short ; the hydrothecae arising from the fascicled stem have rela- 

 tively long pedicels, annulated at each end; those from the simple 

 portion of the stem and from the branches with shorter pedicels, com- 

 monly annulated throughout. Hydrothecae large, 0.5-0.6 mm. in 

 length, broadly campanulate; margin with 16 low, rounded teeth; 

 lines run down the wall of the hydrotheca from the depressions be- 

 tween the teeth. 



Gonoso7ne. — Not observed. 



ry;?^.— U.S.N.M. No. 43454. Taken by the United States Fisheries 

 steamer Speedwell at station 984, latitude 41° 31' N., longitude 69°28' 

 W. off Chatham, Cape Cod, 33 fathoms, August 30, 1881.
