Family ECHINASTERIDAE Verrill 30 



PORANIOPSIS ISFLATA (Fisher), pt. !, p. 261. 



Oregon to San Diego, Calif.; 26 to 159 fathoms; rocks, sand, green mud. 

 This species undoubtedly ranges far south of California, and in deep water it 

 gradually changes to jlexilis. 



PORANIOPSIS INFLATA FLEX1LIS Fisher, pt. 1. p. 261. 



( Ci\i ml and southern California; 334 to 600 fathoms. 



This form probably ranges to the Galapagos Islands where it has been described 

 as P. mira ( Alexandraster minis Ludwig). P. mira (Ludwig) preoccupied in Porani- 

 opsis by de Loriol's P. mira (Fisher, 1911, p. 261). 



HENRICIA SANGUINOLENTA (O. F. Miillcr), pt. 1, p. 271. 



Bering Sea south to the vicinity of the Kuril Islands and on the American coast 

 to Washington. Circumpolar and North Atlantic. In the north Pacific region, 30 

 to 229 fathoms; sand, mud, gravel. 



The above includes variety pectinata Verrill (Cribrella pectinata Verrill), 1914, p. 

 230, Eastport, Me. Variety rudis Verrill, 1914, p. 233, Point Franklin, Arctic 

 Ocean, 13): fathoms, sand. 



Thero seems to be little use in naming the legion of variants of this species. It 

 is questionable whether pectinata of Eastport, Me., is the same as the Bering Sea 

 variation resembling it. 



HENRICIA SANGUINOLENTA forma TUMIDA Verrill. 



Henricia tumida Verrill, 1909, pp. 554, 555, fig. 5; 1914, p. 234, pi. 12, figs. 1, 2. 



Henricia sanguinolenta eschrichtii Fisher, 1911, p. 276, pi. 67, figs. 1-3; pi. 68, 

 figs. 1-2. 



Henricia tumida borealis Verrill, 1914, p. 236, pi. 12, figs. 3, 4. 



Henricia arctica Verrill, 1914, p. 239, pi. 87, figs. 3-3c, text fig. 13. 



Arctic Ocean north of Bering Strait south to Kodiak; westward along Alaskan 

 Peninsula and Aleutian Islands to Bering Island and Kamchatka, to Sea of Okhotsk 

 (Brandt), and south to Simushir, Kuril Islands. Low tide to 53 fathoms. 



This form is exactly equivalent to eschrichtii of part 1. VerruTs name has 

 been adopted since the type is from Unalaska, while that of eschrichtii was from 

 Greenland; and since some doubt exists that the two forms are precisely the same. 

 They are however analogous stouter rayed shallow-water phases of the wide ranging 

 sanguinolenta. 



Verrill applied three names to this forma — tumida, borealis, arctica. Reattributed 

 some importance to the temporarily arched disk of brooding females. His H. tumida 

 borealis applies to specimens with slenderer rays. Both stout and slenderer rayed 

 forms occur in the same tide pool and are in several lots of specimens, as for instance, 

 Nikolski, Bering Island. The narrower rayed variants intergrade with sanguino- 

 lenta. Rarely, for reasons unknown, the rays are short, broad, and flaccid. (Attu 

 Island, Fisher, 1911, pi. 68, fig. 2.) Verrill attributes this specimen to Cape Lis- 



* Verrill described Eehinaster rodtutuj (1914, p. 207), from Sooke, Vancouver Island. I have examined the type; and Dr. H. 

 L. Clark, a photograph ol tbe type tarnished by Dr. \v. R. Coo. Neither Clark nor I believe that robustus came from Vancouver 

 Island nor from a locality within a thousand miles of Vancouver Island. If ••Eehinaster robustus" is not a genuine new species 



I "ilco, or south, it is likely an extra " fat " Eehinaster sentus from Florida. Much of Verrill's material was without attached 

 labels and nothing would have been easier than an inadvertent shift. This actually occurred in the case of " Pisaster lutkenii" var. 



It Equally unlikely are all records of Eehinaster tenuispinus from California and north.
