REPORT ON L.M.B.C. NEMERTINES. 451 



Order I.— PKOTONEMEKTINI, Biirger. 



Family Carinellid^. 



Carinella aragoi, Jonbin. 



G. annulata (pars), M'Intosh, Hubrecht. 

 G. M'i)itosJiii, Burger, Kiches. 

 This species has been dredged not infrequently this 

 year in about 15 to 18 fathoms on the shelly ground to 

 the north of the Halfway Eock, though it does not appear 

 to be abundant. The ground colour in the half dozen 

 examples taken during my visit varied from dark chesnut 

 to chocolate. They were quite small, measuring only 

 from 2 to 7 cm. in length, but an exceptionally large 

 specimen over 20 cm. long in the preserved state was 

 shown to me by Mr. J. C. Sumner who had obtained it in 

 the same locality previous to my arrival. The Port Erin 

 form is exactly similar in external characters to examples 

 of this species seen by myself on the S.W. coast of 

 Ireland and at Plymouth. It is readily distinguished from 

 Garinella annulata, Joubin, Biirger, by the very charac- 

 teristic pale curved ciliated gi'ooves on the dorsal surface 

 of the '' neck," by the absence of a longitudinal white line 

 on the ventral surface of the body, and by the shape of 

 the head which is far less wide than in G. annidata; there 

 is considerably more white on the snout too in G. aragoi 

 and the proboscis pore is more anterior in position. 



?G. anmdata (Montagu). 



Mention has already been made of the possibility of the 

 species recorded as G. annulata in Mr. Yanstone's Report 

 being identical with the last species. No example of the 

 Garinella annulata of Joubin and Biirger has been met 

 with by myself at Port Erin ; there is, however, no reason 

 why it should not occur in the district,
