THE BRITISH PYCNOGONS 541 



A. petiolatus, Kr. (Figs. 270, C; 275, B; 287) (PaUene attenimta and 

 pygmaea, Hodge ; rhoxichilidium exiguiim and longicolle, Dohrn) : Plymouth, 

 Fii'tli of Forth, Cumbrae, Irish coasts. 



Ammothea (Achelia) echinata, Hodge (Fig. 26.5, b; 274, 4; 275, e) : 

 Plymouth, Channel Islands, Isle of Man, Cumbrae, Durham (Hodge), West 

 of Ireland. "We have not found it on the East of Scotland. A. brevipes, 

 Hodge, is presumed to be the young. Two of Dohrn's Neapolitan species, 

 A. fihulifera and A. franciscana, are in my opinion not to be distinguished 

 from one another, nor from the present species. 



A. hispida, Hodge (Fig. 266, c) (A. longipes, Hodge (juv) ; A. magnirostrin, 

 Dohrn ; ? Pasithoe vesiculosa, Goodsir ; ? Pephredo hirsuta, Goodsir) : Corn- 

 wall and Devon (Hodge and Norman), Jersey. The form common on the 

 East of Scotland would seem to be this species. The Mediterranean A. 

 magnirostris, Dohrn, appeal's to be identical. 



A. laevis, Hodge : Cornwall (Hodge), Devon (Norman), Jersey (Sinel). 



Tanijstylum orhiculare, Wilson (Clotenia conirostre, Dohrn) : Donegal 

 (Carpenter). 



Phoxichilus spinosus, Mont. (Fig. 265, C; 270, A ; 275, c) : South Coast, 

 Moray Firth, Firth of Clyde, Ireland. A snialler and less spiny form occurs, 

 which Carpenter records as P. laevis, Grube, but Norman unites the two 

 under the name of Endeis spinosus (Mont.). 



Pycnogonum littorale, Strom (Fig. 262) ; on all coasts, and to considerable 

 depths (150 fathoms. West of Ireland). 



Nymphon brevirostre, Hodge {N. gracile, Sars) (Figs. 263, 264, 267, a; 

 272, 274, 3) : common on the East Coast; Herm (Hodge), Dublin, Queens- 

 town (Carpenter). Our smallest species of Nymphon. 



N. rubruin, Hodge (N. gracile, Johnston ; N. rubrum, G. O. Sars) : 

 common on the East Coast ; Oban (Norman), Ireland (Carpenter). 



N. grossipes, 0. Fabr., Johnston (JV". johnstoni, Goodsir) : Northumber- 

 land, East of Scotland, Orkney, etc., not imcommon. 



N. gracile, Leach {N. gallicum, Hoek ; ^ N. femoratum, Leach) : South 

 of England, West of Scotland, and Ireland. 



N. stromii, Kr. (N. giganteum, Goodsir) (Figs. 273, 274, 2) : East Coast, 

 from Holy Island to Shetland. 



Ghaetonymphon hirtum, Fabr. (Fig, 274, 1) : Northumberland (Hodge), 

 Margate (Hoek), East of Scotland, and Ireland, not uncommon. There 

 seems to be no doubt that British specimens agree with this species as figui-ed 

 and identified by Sars. JV. spinosum, Goodsir (East of Scotland, Goodsir; 

 Belfast, W. Thompson), is, according to Norman, the same species. Sars' 

 Norwegian specimens figured under the latter name are not identical, and 

 have been renamed by Norman C. spinosissimum, but are said by Meinert 

 and Mobius to be identical with C. hirtipes, Bell. 



Hodge (1864) records Nymphon mixtum, Kr., and N. longitarse, Kr., from 

 the Durham coast. His full list of the recorded species of other authors also 

 includes the following doubtful or unrecognised species : N. pdlucidum, 

 N. simile, and N. mimUiim, all of Goodsir. 



Pallene bremrostris, Johnston (P. empusa, Wilson ; ? P. emaciata, Dohrn) 

 (Figs. 275, A ;■ 285) : all coasts. Examples differ considerably in size and 

 proportions, as do Dohrn's Neapolitan species one from another. We have 

 .specimens from the Sound of Mull that come very near, and perhaps agree
