with a slight dorsal ridge. Color, ash-gray above, white below." — 

 Yerrill. 



Ophiopholis Careyi, Lyman. Mouth of Cumshewa Harbour, in 20 

 fathoms, not very common. 

 " Agrees with the description of the original type." — Yerrill. The 

 correctness of the identification of this and of the preceding species 

 has also been corroborated by Col. Lyman, to whom specimens of both 

 were sent. 



Ampluura urtiea, Lyman. Virago Sound, in from 8 to 15 fathoms. 



Several small specimens. Determined by Prof. Yerrill, who 



remarks concerning them : 

 " They have few small spinules on the plates near the edge of the 

 disk. The under arm-plates are squarish, with a notch on the outer 

 edge, as in the original specimens." 



ASTERIOIDEA. 



Asterias epichlora, Brandt. (?) Littoral, and apparently not very 

 common. 

 " Rays five. Spines of dorsal surface evenly distributed, nearly 

 equal, rather long, somewhat enlarged and sulcate at the tips, and sur- 

 rounded, above the base, by a thick wreath of minor pedicellarise. 

 Adambulacral spines in two rows, slender. Ventral spines longer, 

 stouter, obtuse, sulcated at tips, forming four close rows." — Yerrill. 



Aste?ias ochracea, Brandt. The most common of the littoral species 

 collected. 



Asterias hexactis, Stimpson. Pound sparingly at or near low- water 

 mark. 



Leptasterias. (" Near L. Mullen and L. tenera") Virago Sound, in 



from 8 to 15 fathoms, several small and poorly preserved 



specimens. 

 " Bays five, slender. Adambulacral spines slender, mostly two to a 

 plate. Lateral and dorsal spines slender, not crowded." — Yerrill. 

 Pycnopodia helianthoidea, (Brandt.) Stimpson. Below low-water mark 



in Skidegate Inlet, but rather uncommon. 

 Solaster Stimpsoni, Yerrill. Sp. nov. Beach at Bamsay Island, five or 



six specimens. 



" This species is allied to S. endeca of the North Atlantic. It has a 



smaller disk and longer rays, usually ten in number. One of the larger 



dried specimens has the radius of the disk 1-25 inches; of the rays 4 to 



4-50 inches. Color of the disk and base of rays, above, light red ; lower
