out that the bodies on the more caudal situated scales are more lengthened in shape than those on 

 the scales situated more cephalic. The scale figured PI. Ill, Kg. 3 originates from about the middle of 

 the body. - I shall point out only one more feature which I have not seen mentioned in the littera- 

 ture, namely that the microscopical bodies in the scales show tendency to divide in the apex (PI. Ill, 

 fig. 1) a condition also seen in //. rarispina. 



The parapodium and the setae give no information inasmuch as these organs are scarcely to 

 be distinguished in the two forms.

Locality: 



The Faroes; 8 miles E. S. E. off the "Bisp" c. 70 fms. 



Two specimens have been taken at the above named locality of a form which, without hesitation, 

 I am able to refer to Me. Intosh's Harmothoe zetlandica. Some differences between the description 

 of Mcintosh and the specimens under examination are to be pointed out. though they are not very 

 conspicuous. 



On the head (PI. Ill, fig. 7) the frontal prominences seem to be more reduced than is the case 

 in the figure of Mc. Intosh (1. c. PI. XXVIII, fig. 1) and the papilke on the tentacles and the tentacular 

 cirri are not visible as in the same figure 

 of Mc. Intosh. At the low power under 

 which my figure has been drawn they are 

 not seen. The most characteristical feature 

 iu the head is, without doubt, the shape 

 of the paired tentacles; they are very short 

 and have a distinct basal joint; they are 

 rather thick at the base and taper quickly 

 to the terminal point. The unpaired tentacle 

 is nearly as long as the rather long and 

 stout palps. 



The foot (fig. 2) is relatively high 

 and short. The dorsal cirrus is short with a 

 distinct terminal filament, and is beset with 

 sparcely spread, short clavate papillae. The 

 notopodial branch it not very prominent, and 

 relatively few dorsal setie are present. 



As to the geographical range of this species only little is known; the specimens of Mc. Intosh 

 originate from the Shetlauds at a depth of c. 5 fms. Mv specimens have been taken at the Faroes in 

 c. 70 fms.
