Phoxichilus spinosus, Mont. (Fig. [265], C; 270, A; 275, C): South Coast, Moray Firth, Firth of Clyde, Ireland. A smaller 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, Ström (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, Queenstown (Carpenter). Our smallest species of Nymphon.
N. rubrum, Hodge (N. gracile, Johnston; N. rubrum, G. O. Sars): common on the East Coast; Oban (Norman), Ireland (Carpenter).
N. grossipes, O. Fabr., Johnston (N. johnstoni, Goodsir): Northumberland, East of Scotland, Orkney, etc., not uncommon.
N. gracile, Leach (N. gallicum, Hoek; ♂ N. femoratum, Leach): South of England, West of Scotland, and Ireland.
N. strömii, Kr. (N. giganteum, Goodsir) (Figs. [273], 274, 2): East Coast, from Holy Island to Shetland.
Chaetonymphon 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 figured and identified by Sars. N. 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 Möbius 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. pellucidum, N. simile, and N. minutum, all of Goodsir.
Pallene brevirostris, 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 with, Sars’ P. producta, a species that scarcely differs from P. brevirostris, save in its greater attenuation; the same species has also been recorded from Millport and from Port Erin.
