POLYCILETA OF THE L.M.B.C. DISTRICT. 225 



Sthenelais zetlandica — the original specimen of which 

 unfortunately I cannot discover. 



This list — including the last mentioned doubtful species 

 — ennumerates 88 species and two varieties. Both the 

 latter — Polynoe haliceti var. liycence, and Sabella pavonia 

 var. bicoronata are hitherto undescribed : while of the 

 former, one — Dasychone herdmani — is new to science ; 

 three are new to British waters, viz. : — Polynoe (Lagisca) 

 extenuata, Autolytus alexandri, and Ampharete grubei ; 

 and 39 have been found for the first time in this district. 

 Of these the most important are Polynoe castanea, P. 

 johnstoni, Halosydna gelatinosa, Hermadion pellucidum., 

 Sthenelais boa and S. limicola, Spinther oniscoides, Eunice 

 harassii, Onuphis conchilega, Nereis virens, Syllis tubifex, 

 Psamathe ficsca, Castalia punctata, Phyllodoce maculata, 

 Glycera goesi, Ammotrypane aulogaster, Capitella capi- 

 tata, Nicomache lumbricalis, Axiothea catenata, Scoloplos 

 armiger, Cirratulus tentaculatus, Nerine cirratulus, Am- 

 phitrite figulus, Nicolea venustula, Amphicora fabricia, 

 and Serpula reversa. Species recorded for the first time 

 in this district are prefixed by an asterisk, thus : — *S. boa. 

 At the end a table is given showing the world-distribution 

 of local species side by side with details of the distribution 

 of these forms in our own area. The bathymetrical range 

 is also supplied so far as the often scanty data permit of. 

 I fear the details of distribution outside our local area are 

 not so complete as could be wished — several memoirs 

 being out of my reach for consultation. However, so 

 little has been done in the way of tabulating records of 

 distribution that I venture to think that the present may 

 prove useful to students of the group. 



From my observations on the vertical range of local 

 Annelids, I would divide them under three heads — (a) 

 littoral forms, (6) deep water forms, i.e., ranging down-
