No. 8.] WHITEAVES — W. COAST INVERTEBRATA. 467 



Asterias ochracea ? Brandt. Gulf of Georgia, in from twenty to 

 seventy fathoms. One living specimen : J. Richardson, 1875. 

 Rays five, rather long and tapering gradually, disk some- 

 what small. Maximum diameter, three inches and a quar- 

 ter : breadth of disk, three-quarters of an inch. Dorsal 

 spines cylindrical below, bluntly pointed and longitudinally 

 grooved above, thinly scattered and not forming very distinct 

 reticulations. Ventral spines similar to the dorsal, but 

 much more crowded. As the writer has not access to 

 Brandt's original description of this and the preceding 

 species, their identification, which is based upon Stimpson's 

 short summary of their characters in volume six of the 

 Journal of the Boston Natural History Society, is uncertain. 



Asterias hexactis? Stimpsou. One specimen, from the same 

 locality and station as the preceding: J. R., 1874, Rays 

 six, short and tapering rapidly : disk large. Greatest diam- 

 eter, twenty-one lines : breadth of disk, eight lines. Dorsal 

 spines small, short, numerous, arranged in five or six longi- 

 tudinal rows, equal in height, cylindrical, minutely fluted, 

 and subtruncated above. Ventral spiues much longer, di- 

 lated at their summits, and apparently smooth or nearly so. 



Dendra si 'er excentricus, Esch. (Sp.) Abundant in shallow water 

 near Deep Bay, V. I.: J. R., 1875. 



Loxechinus purpuratus, Stimps. Sooke, in the Strait of Juan 

 de Fuca, in one or two fathoms: J. R., 1874. 



Toxopneustes Franciscana, A. Ag. Same locality and collector 

 as for the preceding species. 



Pentacta. Sp. undt. Gulf of Georgia in from 20 to 70 fathoms. 

 J. Richardson, 1875. 



Polyzoa. 



The marine Polyzoa collected by Messrs. Richardson and 

 Middleton have yet to be studied. Most of the species appear 

 to be new, and of those which have been previously described 

 only the three following have been recognized at present. 

 Tubulipora phalangea, Couch. In dead shells at low water 



mark near Victoria : J. R., 1874. 

 Memoranipora lineata, Linn. var. With the preceding. 

 Flustra membranacea, Johnston, as of Linnaeus. Not Mem- 

 branipora membranacea of Johnston or Busk. Near Vic- 

 toria; R. Middleton, 1875.
