Harmothoe imbricata (Linn.) Malmg. 



This species occurs in considerable numbers and from many 

 localities, most abundantly in material gathered in shallow water. 

 The examples from ]McCormick Bay are of large size, and the set£e 

 are nearly black instead of the usual rich amber color; the elytra 

 also are marked with nearly black spots. Many varieties, both in 

 color and structural features, are represented. The elytra vary 

 from those without any trace either of horny papillae or soft mar- 

 ginal papillse, to very rough ones with numerous hard prominences 

 easily visible under a magnification of five diameters and soft 

 papillae so close together that they crowd one another in the mar- 

 ginal rank.

Harmothoe (Evane) impar (Johnston). 



The single specimen from McCormick Bay is typical. In this 

 the soft marginal papillae have the rounded form shown by Malm- 

 gren, not the truncate and lobulated appearance of Mcintosh's 

 figures. The hard papillae are mostly elevated and divided at the 

 summit into two short, blunt divergent processes. The other speci- 

 mens are referred doubtfully to this species, from tj^pical examples 

 of which they differ in the following details: The median and 

 lateral tentacles and the tentacular cirri have the tapering and 

 filamentous portion relatively longer than in INIcIutosh's figure; the 

 scales are rougher, with spinous-tipped horny papillae and few 

 cilia, of which the longer ones have bulbous ends; four examples 

 lack the large, soft papillae altogether, while the fifth one beare a 

 single minute one on one scale only; the neuropodial setae have the 

 spinous tip longer . and the accessory pi-ocess nearer to the extreme 

 end.
