40 AMERICAN HYDKOIDS. 



to 10 rather prominent pointed teeth; diaphragm of the usual campanularian type with a 

 rather deep basal chamber. 



Distribution. — The type-locality for this species is Torquay, southeast coast of England. 

 The other localities are almost all on the coast of Great Britain. Billard reports it from the 

 French Coast "Baia de la Hague," and also as collected by the Travailleur and Talisman 

 on the Atlantic coasts of Spain and Morocco. ? New England Coast (Verrill) ; Vancouver 

 Island (Eraser); Mergui Archipelago (Ritchie); Japan (Stechow). 



This species certainly resembles very closely C. inconspicua (Forbes) as described by 

 Calkins, but also agrees very exactly with Hincks's figures and descriptions even in the bulbous 

 swelling at the bases of the pedicels which Calkins regards as the main distinction (in the absence 

 of the gonosome) between the two species.

TropTiosome} — Colony in the form of a creeping rootstock growing profusely over the 

 stem and branches of other hydroids. Torrey has noted the interesting fact that the hydro- 

 caulus, when free from the surface over which it grows, is closely annulated like the pedicels; 

 but when the creeping rootstock is adherent to the host it is smooth and not aimulated. The 

 pedicels are closely annulated throughout, unbranched, rather thick-waUed and stiff, attaining 

 a height of about 3 mm. In the ^'urceolata" type proper they are often short, sometimes shorter 

 than the hydrothecae. Hydrothecas exceedingly variable in shape, the tj^iical ones being 

 distinctly urceolate, about 1.5 times as high as broad, the margin with distinct rounded or 

 undulating teeth about 14 in number. The bottom of the hydro theca is thickened in such a way 

 as to leave a basal chamber that looks much like an included last annulation of the stem. The 

 "reduplicata" type of hydrotheca is narrower but about as long as the other, with the margin 

 often reduplicated from one to three times. 



Gonosome. — The gonangia vary from a roughly oval form with a wavy outline to ovoid 

 regular forms with a short neck and even, round aperture. The contents are sporosacs. 



Distribution. — The type-locaHty is Lituya Bay, Alaska (Clark); Yakutat Bay, Alaska 

 (Nutting) ; California (Clark) ; San Francisco, Tomales Bay, and Pacific Grove, Cal. (Torrey) ; 

 Puget Sound (Nutting). 



I agree with Torrey that C. urceolata includes my C. reduplicata.
