REPORT ON THE VERMES. 145 



chcetopterus typicus, Thelepus circinatus, Dasychone lucul- 

 lana, Filograna implexa, Protula protensa, among the 

 PolychsBta. 



A few observations, more especially on the Polychseta of 

 the collection, form a distinct paper. 



Class.— Platyelmia. 

 Order IV. — NEMERTEA. 



Sub-order.— ANOPLA. 



Family .^Malacobdellid^ . 



Malacohdella grossa, 0. F. Miiller. 

 A fine specimen of Malacohdella grossa was obtained 

 parasitic in the shell of a live Cyprina islandica, which was 

 found on Lavan Sands, Llanfairfechan. 



Family. — Lineid-e. 



Carinella linearis, Montagu. 

 An example of this species was dredged off Port Erin, 

 Isle of Man. In colour, form, and anatomical features it 

 agreed entirely with Montagu's description, as also with 

 Mcintosh's notes in his Ray Society Monograph on the 

 Nemertea. The specimen was of a brick red colour, with 

 white bands, when living, but after preservation in alcohol 

 was of a yellowish white colour, the pale bands and annula- 

 tions being pure white. Only about 1^ in. of the worm 

 was preserved, and that fragment tended to break into 

 segments at the white annul ations. 



Lineus mai-inus, Montagu. 

 A specimen of this species was obtained in Bay Fine, 

 Isle of Man, coiled around the dredge and its contents. 

 The bottom was composed of stones and loose seaweed. A 

 specimen was also found by Mr. R. D. Darbishire on the 

 beach, east of Beaumaris.
