346 Mr. J. F. Whiteaves on Deep-sea Dredging 



sembling in some respects some of the varieties of P. phos- 

 phorea as described by Kolliker, seems nevertheless a distinct 

 species, for which I venture to propose the name oi Pennatula 

 canadensis. On this point Prof. A. E. Verrill, to whom I 

 sent specimens, writes to me as follows : — " I have spent con- 

 siderable time on the Pennatula. It is very near P. pJios- 

 phorea^ and for a time I thought it would prove identical. So 

 far as the figures and descriptions of the latter go it agrees 

 very well, allowing that all the varieties and subvarieties re- 

 cognized by Kolliker really belong to one sjDccies ; but on 

 comparison with Norwegian specimens, received from Copen- 

 hagen, it seems to be sufficiently distinct. The most evident 

 differences are to be found in the more numerous, crowded, 

 and unequal rudimentary or asexual polyps along the back of 

 the stalk in your species, and in the greater smoothness of 

 the peduncle, due to the much smaller size of the spicula of 

 the integument in the American species." For many of the 

 details respecting this species I am indebted to my friend Mr. 

 G. T. Kennedy, M.A., of Montreal, who has kindly helped 

 me in the dissection of specimens. 



ECHINODERMATA. 



Two fine living examples of ScMzaster jragilis (the Brissus 

 fragilis of Diiben & Koren) were dredged, one off Cap-Rosier 

 lighthouse, in 125 fathoms, the other from 200 fathoms, in 

 the centre of the river, between Ellis Bay, Anticosti, and the 

 south shore. Off Sawhill Point, on the north shore, the 

 dredge brought up, from 69 fathoms, a curious Asterid covered 

 with long and slender spines. Prof. Agassiz, to whom I sent 

 the only specimen collected, informs me that it is identical 

 with a species dredged on the ' Porcupine ' expedition, and 

 subsequently named by Prof. Wyville Thomson Calveria 

 hystrix. Prof. A. Agassiz thinks that this Asterid may be 

 the Solaster furcifer of Diiben & Koren. Unfortunately two 

 widely different Echinoderms are called Calveria hystrix in 

 the ' Proceedings of the Royal Society.' The St.-Lawrence 

 starfish is the " singular Asterid allied to Pteraster^'' but not 

 the Echinoderm " belonging to the Diadema family," to 

 both of which the same name is given. Ctenodiscus crispatus^ 

 Diiben & Koren, was abundant in every haul at depths 

 greater than 100 fathoms. Amphiura liolhollii^ Liitken, and 

 Ophiacantha spirudosa, Miill., were also frequent in deep 

 water. Large living examples of Op>hioglypha Sarsii, Liitken, 

 were dredged in 125 fathoms off Cap-Rosier lighthouse, 

 and a few fine specimens of Astrophyton Agassizii were taken, 

 from 60 fathoms mud, off Thunder River.
