There being no suitable specimen at hand for description the following is compiled from 

 the technical description of Hincks' together with his remarks in the species. 



Trofhasome. — Colony ^ of an inch in height, stem fUiform, flexuose, giving off alternate 

 pedicels and with 4-7 annulations on the stem above each pedicel origin. Pedicels annulated 

 proximally and distally, usually longer than the hydrothecce. Hydrothecse deeply campanu- 

 late, about twice as long as broad and ^vith about 8 bimucronate marginal teeth. Hydranth 

 with 15-16 slender tentacles. 



Gonosome. — Gonangia pyriform, axillary or borne on the pedicels with a short annulated 

 stalk. Gonangial contents a blastostyle with a sporosac. An acrocyst is formed in which the 

 ova develop into the planula stage. 



Distribution. — American: Woods Hole Region (Nutting); New England Coast (VerriU). 

 General: Type-iocahty is Cidlercoats and Tynemouth, in the north of England. Other locaU- 

 ties, Devon and Cornwall (Hincks); North Sea (Schulze); Denmark (Winther); ScUly Isles 

 (Browne and Rupert).

Trophosome.^ — Pedicels unbranched, springing from a creeping rootstock which is not regu- 

 larly annulated. Pedicels usually longer than those of C. speciosa, sometimes three times the 

 length of the hydrotheca, usually annulated throughout. Hydrothecse deeply urceolate or 

 tubular, considerably more slender than in C. speciosa. Hydrothecse large, attaining a length of 

 2.5 mm. Margin evenly fluted or crenulated with usually 10-12 elevations and depressions. 

 The distal part of the hydrotheca is marked by parallel hues running down from the margin 

 and reaching about one-third the length of the hydrotheca. Hydrothecse 3J to 4 times as long 

 as broad. 



Gonosome. — Gonangia borne in the creepiag rootstock with a very short pedicel and slender 

 ovate body produced distally mto a slender tubular neck ending in a round orifice. Gonangia 

 approximately as long as the hydrothecse and about thi'ee times as long as broad, gonangial 

 walls sometimes corrugated. Gonangial contents (of another specimen, off Newfoundland) 

 ova, showing that the species is a Campanularia. 



Distribution. — Type-locahty, off Canso, Nova Scotia, 50 fathoms. Other specimens are 

 from station 2699, off Newfoundland, 72 fathoms. 



The drawings of this species had been made and referred to O. speciosa, until Doctor Fraser 

 made drawings of a specimen of C. speciosa from the Shumagin Islands and compared them 

 with the present species. The most marked difference, however, is in the gonosome, the 

 gonangia being of entirely diverse types.
