358 EVARNE JOHNSTONI. 



examination of the microscopic preparations has been made. The form agrees with the 

 typical British examples. Malmgren's artist had omitted the cilia on the ventral cirrus, 

 while in the description they are not mentioned. Baron de St. -Joseph, in a recent 

 publication, 1 alludes to the same form, and appears to agree with the original author in 

 thinking it necessary to make a variety. 



Another well-marked variety was procured between tide-marks, Herm, under a stone 

 in August, 1868, and also at Lochmaddy, North TJist. While in regard to the general 

 outline, the shape of the head, the position of the eyes, and the arrangement of the 

 pigment on the dorsum, it agrees with the ordinary form, the dorsal bristles are shorter, 

 though they do not deviate from the typical structure ; and the same may be said of the 

 ventral. .The scales, however, vary, since the cilia on the outer border are shorter than 

 usual, and have large ovate heads containing granular epidermic elements ; some of these 

 also occur within the posterior border, while along the whole of the latter is placed a 

 short series of cilia with large globular heads and short stalks, the terminal ones only 

 towards the inner border becoming ovoid instead of globular. The general surface of 

 the scale is studded with larger tubercles ; and few of the others, except towards the inner 

 region, and one or two of those near the posterior border, assumed considerable pro- 

 portions, while none were so large as usual. A similar variety in regard to scales was 

 procured by Dr. Grwyn Jeffreys in 1868 in ninety fathoms ofE North Unst, Shetland, but 

 the ventral bristles were more slender, both somewhat approaching those of E. Johnstoni, 

 though the dorsal were more tapered towards the tip. The specimen was a male.

Specific Characters. — Distinguished from E. im/par by the deep brownish hue of the 

 dorsum, and the brownish-purple proboscis ; eyes more minute, the anterior pair not 

 visible from the dorsum. Scales with fewer and larger horny papillae, longer, fewer, 

 and more delicate cilia along the posterior and outer borders. Dorsal bristles more 

 slender and less tapered distally ; ventral more slender, and with longer bifid tips.
