176 Mr. W. Small on Annelica Polychceta 



Evarncjohnstoni, M'lntosh, 1876. 



This species has previously been obtained only from the 

 Atlantic Ocean to the west of Ireland. Tiie present record is 

 the first of it from the seas to the north of the Shetlands, 

 where it was obtained in 362 m. The haul consists of one 

 fragment of a few anterior segments. M'lntosh gives the 

 lenofh of his examples as 9 mm. 



The dorsum shows a distinctive deep brown colour and the 

 proboscis is characteristically tinted. Contrary to the usual 

 condition, it is not extruded. The body, however, is 

 ruptured. 



The eyes are moderately large and of a brown colour ; only 

 the posterior pair is visible from above. 



No scales are present. The bristles are characteristic and 

 are alone sufficient to identify the annelid. 



The pr.sent example may be a variety, for the eyes are 

 not the " minute black poinis " described by M'lntosh (1900, 

 p. 351:'). At the same time his figure of the head of E.jolin- 

 stoni (1900, pi. xxvii. fig. 7) shows the eyes large enough to 

 be those of the present specimen and too large for his 

 description of them. 



Evarne atlantica, M'lntosh, 1897. 



An anterior fragment of this annelid, which was first 

 brought to light by the lioyal Irish Academy's Expedition 

 (1896), was taken in 21 fathoms in the Moray Firth in the 

 same haul which yielded A jiho'odlta echidna. 



Both pairs of eyes are veiy conspicuous from the dorsum. 

 Brown and pink are the characteristic tints of the dorsal 

 region. The scale-bearing tubercles and the lateral borders 

 of the segments which do not bear scales are outlined in dark 

 brown. Internal to these markings there are, on each 

 segment, patches of a paler brown colour, and along the mid- 

 dorsal line bars of dark brown on a band of pink, which 

 passes along the whole length of the fragment, mark the 

 posterior border of each segment. The doisal coloration thus 

 differs from that of the original specimen (M'lntosh, 1900, 

 p. 363). The feet and ventral surface are pink in colour 

 and the bristles are pale yellow. 



The scales, which are unknown, cannot be described 

 because of their complete absence. Prof. ]\I'Intosli thinks 

 that they approach those of E. normani.
