116 WHITEAVES ON MARINE INVERTEBRATA, ETC., 



ASTEROIDEA. 



ASTERIAS OCHRACEA, Brandt. Low water, Malaspina Inlet, one small specimen. 



ASTERIAS CONFERTA, Stimpson. Low water, Malapina Inlet, five fine specimens. Discovery 

 Passage, at low water, one specimen. 



ASTERIAS TROSCHELI, Stimpson. Several specimens of an Asterias with five long slender 

 rays and a very small disk, which are probably referable to this species, were 

 collected by Dr. Dawson at low water at the northern end of the Strait of Georgia, 

 at the entrance to Malaspina Inlet, at Kedonda Island (to the north-east of Cortez 

 Island) and in Discovery Passage. The smaller specimens from these localities 

 agree very well with Stimpson's description of A. Troscheli; but the larger ones, 

 which attain to a maximum diameter of rather more than a foot, and which are not 

 very well preserved, do not shew very clearly the peculiar pentagon formed by 

 clusters of spines in the centre of the upper surface of the disk, nor the marked 

 disparity in size between the larger and smaller dorsal spines, that are said to be 

 characteristic of the species. These larger specimens are precisely similar to a star- 

 fish collected by Mr. James Richardson in 18*74, at low water, near Victoria, 

 Vancouver Island, which was doubtfully and perhaps incorrectly referred to the 

 A. epichlora of Brandt in the " Canadian Naturalist " of December, 18*78, but both 

 they and it are quite different to the specimens from the Queen Charlotte Islands 

 which were called A. ejrichlora, but with a query, by the writer, on Prof. Verrill's 

 authority, in an appendix to Dr. Dawson's report on those islands. 1 Since that 

 appendix was written, however, two very typical and well preserved examples of 

 A. Troscheli have been detected among Dr. Dawson's collections from the Queen 

 Charlotte Islands. 



ASTERIAS HEXACTIS, Stimpson. Taken rather sparingly, living, at low tide in Seymour 

 Narrows, Discovery Passage, Johnstone Strait and Queen Charlotte Sound. A few 

 badly preserved and small specimens of a six-rayed star-fish, which is also 

 probably A. hexactis, were dredged at station No. 14. 



PYCNOPODIA HELIANTHOIDEA, Brandt. (Sp.) Hernando Island, Strait of Georgia, at low 

 water, one specimen. 



SOLASTER STIMPSONI, Verrill. Low water at Port Neville, on the mainland of British 

 Columbia and on the north side of Johustone Strait, several. Twelve specimens of 

 a Solaster, which seems to be only a variety of this species, were dredged in Queen 

 Charlotte Sound at station No. 14. These differ from the type of S. Stimpsoni prin- 

 cipally in the unusually large size of the disc and in the shortness of the rays, 

 which latter are uniformly ten in number. The spines at the angles near the 

 mouth, also, are apparently more numerous. 



SOLASTER DAWSONI, Veirill. Beach at Powell Island, Strait of Georgia ; one adult example. 

 Entrance to Malaspiua Inlet, at low water ; one small specimen. Low water at 

 Johnstone Strait and in the Goletas Channel ; abundant.
