Tubularia elegans, sp. nov. 

 Plate XXXVIII, figure 2. 



Stems clustered, rooted by a creeping stolon, erect, unbranched, 

 more or less annulated at intervals toward the base. Hydranths 

 large, with about thirty tentacles in the proximal set and twenty to 

 twenty-four in the distal. Gonophores borne in clusters just inside 

 the proximal tentacles, twelve to twenty in a cluster, each of the 

 larger ones crowned with four conical tubercles. Height of tine.st 

 specimen, 75""". 



Collected on the piles of the wharf at San Diego, by Dr. E. Palmer 

 1875. Intermingled with it and often attached to it were numerous 

 shoots of Blmeria. Many of the young had attached themselves to 

 the parent stalk, giving at first sight the appearance of branching 

 stems. , 



The specimens from which this species is described were crowded in 

 the same can with the Bimeria described above, and are in the same 

 dilapidated condition. There is a Tubularian, Tha/mnocnidla tuhular- 

 oides, from the Bay of San Francisco, described by A. Agassiz (Cat. 

 of N. A. Acalephje, p. 196), which he says "is readily distinguished 

 from its eastern congeners by the stoutness of the stem and large size of 

 the head." The description is a very meagi-e one, but from these two 

 characters I conclude that it must be distinct from T. elegans, for the 

 latter spetaes has neither a stouter stem nor larger head than Tham- 

 nocnidia spectahilis of the New England coast. 



Eudendrium, sp. 

 Plate XXXVIII, figure 1. 



We have also received from the California coast the perisarc or 

 chitinous portion of what I take to be a species of Eudendrium. 



Stems stout, erect, dark horn color, strongly annulated throughout, 

 rather sparingly branched ; branches sub-erect, springing from all 

 sides of the stem and much divided. Hydranths borne at the ex- 

 tremity of the short ramuli. The entire perisarc is strongly ringed, 

 giving it a close resemblance to the trachete of an insect. Height of 

 largest specimen, 80"'"'" 



Santa Cruz, Bay of Monterey, Cal., — Dr. C. W. Anderson. 



Campanularia everta, sp. nov. 

 Plate XXXIX, figure 4. 

 Stems rather stout, arising at intervals from the creeping stolon, 

 with two annulations at the base of the hydrothecte, the lower one
