Henricia spatulifcra Verrill (10096, p. 5.')4, %. 6) from soutlioast Alaska lias not 

 yet been destribcil, so tliat it is not inciudoil in tliis report. I liavc not recofjnizeil 

 it in the collections, althoufjli the lisiuro of (ho ndamhulacrnl and niar};inal plates is 

 not alone sidlicient for purposes of identification. Both //. hriuscuh and //. 

 letnusula multispina ma}- have spatulate adamhulacral spinelets.

This widely distributed and variable species is representeil in the rejrion of Berin<; 

 Sea by two well-marked forms which it has been deemed advisable to separate under 

 different names. One of these is the common Ileitricia of the jVleiitian Islands, the 

 shores of Bering Sea and Arctic Ocean to the east, and t)f the Kamchatknn-Okhotsk 

 region. It is a short-rayed thick-set foiTa with conspicuous marginals and has In-en 

 called Henricia sanguinolcnta eschrichtii (Midler and Troschel). It differs markedly 

 from typical sanguinolenta of Norway. The other form is perhaps more variable 

 than the first, and is found usually in deeper water. It has longer, slenderer rays, 

 more numerous adamhulacral spinelets, and an inconstant arrangement of the ven- 

 tral plates in regular series; sometimes there is no sign of regular marginals; some- 

 times only a series of actinal intermediates is present, all the plates above being 

 irregularly arrangetl. In an aberrant variety, j)ossibly the result of hybridization, 

 the marginals are large and conspicuous (station 47S4).
