rows of spines. The latter are also recurved. The spines 

 decrease in number and size towards the tip, and the bitid 

 portion of the bristle is entirely naked. This part is slightly 

 swollen immediately below the bifurcation. 



The inferior ventral bristles (fig. 5) are more massive than 

 the superior. Their outline recalls the hastate bristles of 

 Aricia. The spines are confined to the thicker lower portion 

 of the bristle, leaving a large smooth tip the edges of which 

 are not so straight and uniformly converging as shown by 

 Malmgren, 



Trautzsch (1889, pp. 139 & 143) gives as references to 

 Ilarmotho'e villosa, Levinsen (1883, pp. 36, 193) and Malra^ 

 gren (1865, pp. 79-80), and to Eucranta villosa, Malmgren 

 (1865, pp. 79-80). The references to Malmgren are identical, 

 while Levinsen, as Trautzsch remarks, does not mention the 

 genus Eucranta, but refers to what is undoubtedly the same 

 form as Harmothoe villosa, and himself gives the same 

 reference to Malmgren. Yet Trautzsch mentions the two 

 names, H. villosa and E. villosa, in places apart in the text 

 and in a table of dredgings as if they were distinct species. 

 His drawing of a ventral bristle of //. villosa (L889, pi. vii, 

 fig. 16) does not resemble either Malmgren's original drawing 

 of a ventral bristle of Eucranta villosa or the appearance of 

 the same in the fragment of the annelid under discussion,

Genus Sthenelais, Kinberg, 1857. 



Sthenelais boa (Johnston, 1833), Kinberg, 1857, 



One incomplete specimen of 17 mm. length was dredged 

 from a depth of 5 fath. in Quey Firth, Shetland. 



It is remarkable that the representation of this form, 

 which ranges from Norway along the western shores of 

 Europe to South Africa, should be so small. The specimen 

 presents no points of difference from the typical British form 

 except in coloration. The head is not of a crimson hue nor 

 are the few scales present on the dorsum marked with grey 

 or brown. 



Sthenelais zetlandica, Mcintosh, 1876. 



Two small fragments, one anterior, the other posterior, 

 were found in Shetland waters, 



The head is injured, and therefore its structure cannot be
