much longer and more numerous than in L. rarispina. The ventral cirri have a few 

 short cilia, and extend nearly to the tip of the fleshy portion of the foot. 



The dorsal division of the foot has somewhat stout bristles (PI. LXXI. fig. 9), and the 

 tip has a tendency to follow the same form as in the ventral. This is observed in a 

 more highly magnified view in fig. 10, while another with a sharper tip is seen in 

 PI. LXXIII. fig. 17, and a third in PI. LXXIII. fig. 18, sketched from one of the short ar 

 (developing 1) forms toward the body-line of the dorsum, and having a slender process 

 at the tip. The ventral division commences superiorly with a series having very long 

 tips, the rows of spines being much finer and more dense than in Harmotho'e imhricata 

 — indeed, in this respect approaching Dasylepis asperrima. The peculiar shape of the 

 terminal portion is distinctive (PL LXXI. fig. 11, representing one of the longer, not 

 longest, forms). Some of those next the upper series also show a distinct process 

 beneath the tip (PI. LXXI. fig. 12). The tips diminish in length in the usual manner 

 toward the ventral surface, those at the lower edge showing no secondary process. 



Malmgren's descriptions and figures demonstrate considerable diflTerences between his 

 forms (L. rarispina and L. propinqua) and the present. It is a fact of interest also in 

 connexion with the strictness necessary in all scientific drawings, that his artist has 

 overlooked the fundamental condition of such bristles, viz. to have alternate rows of 

 minute spines or spinous processes. None of the specimens exhibited the elongated 

 processes on the scales shown by Malmgren in L. rarispina, and, in some, few or none 

 of the bristles of the inferior branch showed the secondary process beneath the tip — 

 characters which diverge both from the latter and L. propinqua. 



Harmothoe imbricata, L., occurred in 60-160 fathoms six miles E. of Cape de Gatte. 

 In a specimen oi HarmotJioe Jloccosa, Sav., dredged ofi" the west coast of Ireland in 173 

 fathoms, some of the posterior ventral cirri had a few clavate papillas. Harmothoe anti- 

 lopes, M'Intosh, is not uncommon in both collections, being found with the latter in 

 (No. 6) 358 and (No. 11) 567 fathoms on the Channel slope, in the Atlantic, and 

 outside Gibraltar in 227 fathoms. 



EvAENE IMPAE, Johnst. An example from 567 fathoms (Station No. 1, 1870) does 

 not show the large tubercles on the scales, and the cilia along the border of the latter 

 are unusually long. The characters in some respects (except the slenderness of the 

 ventral bristles) approach certain varieties of Ilarmotho'e imhricata. The scales, more- 

 over, have none of the ordinary brown touches, being pale greyish. The same variety 

 was procured in Station No. 6 (358 fathoms), and outside Gibraltar.
