4 NEW INVERTEBRATA FROM 



The tentacles are long, filamentous, with scattered ne- 

 matocysts. The tentacular bulbs are large and promi- 

 nent and of a yellow color, each with a prominent black 

 ocellus. There are four narrow, unbranched, radial chym- 

 iferous tubes. 



In a younger specimen (fig. 2) the outer surface of the 

 bell is strewn with clusters of nematocysts. This imma- 

 ture form has but a slight apical prominence and the ten- 

 tacles are shorter and more stumpy than those of the adult. 

 This species was found in the Bay of Monterey, at San 

 Francisco and at Santa Barbara. 



Syncoryne rosaria a. Ag. 



(PLATE IV, FIGS. 1, 4.) 



This hydroid^ was collected in great quantities on the 

 spiles of the wharf at Santa Barbara, where it occurs upon 

 the fronds of alo£e and the tunics of Tunicates and other 

 animals. It forms small clusters consisting of hydroid 

 heads ffrowino^ from branching basal tubes. Each tube, 

 bearing a single head, is unbranched. 



The head is white, or slightly pink in color, with five 

 terminal, club-shaped tentacles, forming a ring about a 

 central mouth-opening. The remaining tentacles of the 

 head are more scattered, and arranged with little regular- 

 ity, but are found in all conditions of growth and of va- 

 rious sizes. 



Cainipanularia occidentalis sp. nov. 



Prof. S. F. Clarke mentions three species of Campan- 

 ularia from our Pacific coast. (7. everla is recorded from 

 San Diego ; C. fusiformis from Vancouver Island and 



1 This is supposed to be the same as tlie Coryne of A. Agassiz, but as he does 

 not give a flijiire of C. rosaria I am not sure that tliey are identical. 



I have followed Allnian iu limiting tlie name Syncoryne to those Corynidas 

 with free hydroid Medu6i«.
