EXPEDITION TO POINT HAHUOW, ALASKA.

8. ASTERIAS sp. 



A few specimens of a small Asleriax with live arms were dredged in about 7 fathoms, on a 

 pebbly bottom, oil' Port Clarence. They undoubtedly belong to the genus Anterias, but the species 

 is not detenuinable with any means at my command. 



9. LEPTASTERIAS ARCTICA (Stimpson). 



Oft' Point Franklin, in 13i fathoms, we dredged large numbers of a small starfish which cannot 

 be distinguished, from a dried specimen in the National Museum, brought from Ik-ring Strait by 

 the North Pacific Exploring Expedition and labeled in Dr. Stimpsoifs handwriting Axtn-iax arc- 

 tica var. a. I have been unable to find a published description of this species. 



The size and position of the papulae on the back and sides of the arms show that it belongs to 

 Vorrill's genus Leptasterlu*. 



The following is a description of the species: Bays five, rounded above, elongated, tapering 

 regularly to the tips. lladii as 1:3.5. Disk small, its radius about equal to width of ray at base. 

 Interambulacral spines round and slender with rounded tips, usually two to each plate. No small 

 spines between these and the ventral spines. Tentral spines form a double row ol' alternating 

 spines, of which the upper are the smaller and the lower are larger and stouter than the interam- 

 bulacrals. Lateral spines rather slender, forming a single row. No well-marked dorsal row, though 

 the spines in the middle of the arm are rather the larger. The dorsal spines are short and stout, 

 with rounded, almost capitate, tips. The spines of the disk are rather smaller than those of the 

 arms and are arranged irregularly. The major pedicellarire could not be well made out, but 

 appeared to be lanceolate and not numerous. The minor pedicellarire form close wreaths around 

 the spines. 



Diameter of the largest specimen about 7a miu .

One lare specinien and a number of very small ones were dredged off Point Franklin, but 

 none were obtained, elsewhere. 



The species has been recorded from the eastern coast of North America, from Nantncket Shoals 

 to Labrador and Greenland, and southward on the European coast to Norway and Great Britain, 

 also from Nova Xembla, Spitsbergen, the Arctic Ocean north of Bering Strait, and the Sea of 

 Ochotsk (Brandt 1i:xt< : Liitken, op. <'it., p. 02).
