bearing large papillse, lack distinct marginal areas; 4260, Dimdas Bay, 

 Icy Strait, 8^21 fathoms, coarse sand and rocks, one similar to the 

 last but more distinctly colored; 4259, same region, 21-78 fathoms, 

 gray sand, broken shells and rocks, a small example with well-marked 

 marginal areas on the elytra but few large papillse and with the inter- 

 sections of the ridges between the areas sometimes produced into large, 

 coarse cilia.

This is another species which was originally incorrectly attributed to 

 Greenland, the type locality being almost certainly Icy Cape, Alaska. 

 Like Hermadioa truncata it is rather plentiful in the collections from 

 the Gulf of Georgia to Behm Canal, being represented, mostly by frag- 

 mentary specimens, in the collections from the following : 



Stations 4193, Halibut Bank, Gulf of Georgia, B. C, 18-23 fathoms, 

 green mud and fine sand; 4194, same region, 111-170 fathoms, soft 

 green nuid; 4197, same region, 31-90 fathoms, sticky green mud and 

 fine sand; 4199, Queen Charlotte Sound, off Fort Rupert, Vancouver 

 Island, B. C, G8-107 fathoms, soft green mud and volcanic sand; 4223, 

 Boca de Quadra, southeastern Alaska, 48-57 fathonx^;, soft green mud ; 

 4228, vicinity of Naha Bay, Behm Canal, southeastern Alaska, 41-134 

 fathoms, gravel and sponges. 



The species appears to be especially common at the last enumerated 

 station and several fragments taken here depart quite widely from the 

 typical form in the character of the elytra. These are designated as 

 variety papillata, characterized as follows : The elytra bear more num- 

 erous, larger and differently shaped soft papillae and very much fewer 

 and smaller hard conical papillae; and instead of the numerous long 

 cilia on the exposed surface and near the outer margin of the elytra of 

 the typical form, these bear only a few very much shorter cilia with 

 thickened ends.

Occurring quite plentifully in the collections from the more northerly 

 points in the Alaskan Gulf, where it apparently largely replaces L. 

 multisetosa, this species is represented by two varieties which are, 

 however, connected by intermediates and apparently occur indis- 

 criminately together at the same stations. 



The difference is in the presence or absence of the soft marginal
