SHALLOW- WATER STARFISHES 137 



Sitka, Fox Cape, Yakutat, Dutch Harbor, Aleutian Islands and 

 Wrangel (Harriman Expedition). Common at Sitka at low tide. 

 Many of the specimens have large clusters of very young ones 

 beneath them over and around the mouth. (PI. LXXXV, figs. 2-2e.) 

 Queen Charlotte Islands ; Vancouver Island ; Puget Sound ; etc. 



Among the young attached under the mouth of the mother, were 

 both six-rayed and five-rayed ones ; the former much more numerous. 



Among 630 young, taken from several six-rayed mothers, and 

 carefully counted, there were 596 of the six-rayed sort; 31 five- rayed ; 

 3 four-rayed. I have seen no adults that are four-rayed. 



A six-rayed specimen from St. Paul's Island (coll. H. W. Elliott, 

 U. S. Nat. Mus., No. 3267) is somewhat peculiar. It is 90 mm. in 

 diameter, with the rays narrower, more depressed and more acute 

 than usual, so that it resembles A. borealis in form. But the dorsal 

 spines are much as in alaskensis, very numerous, crowded, arranged 

 in a reticulate or areolate manner, and all capitate. The mar- 

 ginal rows are double, and also the interactinal row proximally. 

 These spines are stout, clavatc. The adambulacral spines are stouter 

 than usual, especially the outer ones, and decidedly clavate. On the 

 sides of the rays are a few large, erect, blunt pedicellariae, nearly as 

 stout as the adjacent spines. This, like several other odd specimens, 

 may be a hybrid between L. epichlora and A. borealis.

NELLA Verrill, nov. 



Plate xvi, figures I, 2. 



Normally six-rayed. Rays short, rounded. Dorsal ossicles and 

 spines small, capitate, arranged as in alaskensis, except that there is 

 a distinct median radial row, larger than the rest. Infero-marginal 

 and oral spines as in typical specimens. Large erect major pedi- 

 cellariae are present sometimes. 



Most of the examples of this variety are young, up to 50 mm. in 

 diameter. Probably there is a general tendency for the median dorsal 

 row of spines to become indistinct in larger specimens, though this is 

 not always the case in this species.

Disk large ; rays usually six, rather short and stout. Radii, 14 mm.
