254 S. F. Clark— Hydr Olds of the Pacific Coast. 



smaller than the upper; the remainder of the stem has a wavy outline 

 or is slightly annulated, Hydrothec^ broadly campanulate, not 

 deep, tapering more or less gradually from the distal end to the base, 

 the rim strongly everted and bearing about fifteen rather shallow 

 teeth. Gonothecje, large, turgid, nearly cylindrical, tapering a little 

 at the base, borne on short, stout peduncles and with the aperture 

 terminal, small and cylindrical. 



Found creeping on an Alga from San Diego, Cab, — H. Hemphill. 



This is a very pretty form and may readily be distinguished by the 

 broad hydrothecae with their strongly everted, toothed rims. The 

 peculiar shape of the gonothecte is also very characteristic. 



Campanularia cylindrica, sp. nov. 

 Plate XXXIX, figures 1-r'. 

 Stems are simple, unbranched pedicels, of very variable length, 

 more or less annulated over the entire length and with a single well- 

 marked ring at the base of the hydrothecje, rooted by a creeping, 

 twisted stolon. Hydrothecte campanulate, nearly cylindrical, taper- 

 ing but very slightly toward the base, varying greatly in depth, rim 

 armed with about fifteen very shallow, sharply pointed teeth. The 

 gonothecse also show considerable variation in size, there being occa- 

 sionally one or two which are at least twice the size of the ordinary 

 form; they are subfusiform, tapeiing sliglitly more toward the proxi- 

 mal than the distal end, supported on short pedicels with one or two 

 annulations. 



Campanularia fusiformis, sp. nov. 

 Plate XXXIX, figures 2-2-. 



Hydrocaulus simple, creeping, bearing the pedicels at irregular 

 intervals; ])edicels of variable length, usually two or three times 

 the length of the hydrothec;^, never more than six times their 

 length, with a more or less w^avy outline. Hydrotheca? small, deeply 

 campanulate, tapering at the base, rim ornamented witli about twelve 

 stout, shallow, acute teeth, a single distinct annulation at the base. 

 GonotheciB small, fusiform, constricted at both ends, sessile, aperture 

 small, terminal. 



Vancouver Island, — J, M. Daw^son. Found growing on Sertularia 

 angidna var. rohusta. 



This species is closely allied to C. cylindrica of the Californian 

 coast from which it may be distinguished by the size of the hydro-
