XXI THE BRITISH PYCNOGONS 541 
A, petiolatus, Kr. (Figs. 270, ¢; 275, B; 287) (Pallene attenuata and 
pygmaca, Hodge ; Phoaichilidiwm exiguum and longicolle, Dohrn): Plymouth, 
Firth of Forth, Cumbrae, Irish coasts. 
Ammothea (Achelia) echinata, Hodge (Fig. 265, B; 274, 4; 275, £): 
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. fibulifera 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. magnirostris, 
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. 
muagnirostris, Dohrn, appears to be identical. 
A. laevis, Hodge: Cornwall (Hodge), Devon (Norman), Jersey (Sinel). 
Tanystylum orbiculare, Wilson (Clotenia controstre, Dohrn): Donegal 
(Carpenter). 
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, Strém (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. 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): Northumber- 
land, East of Scotland, Orkney, etc., not uncommon. 
N. gracile, Leach (N. gallicum, Hoek; p N. femoratum, Leach): South 
of England, West of Scotland, and Ireland. 
N. strémii, Kr. (N. gigantewm, 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. spinoswm, Goodsir (East of Scotland, Goodsir ; 
Belfast, W. Thompson), is, according to Norman, the same species. Sars’ 
Norwegian specimens figured under the latter naine 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. 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
