CaRrPENTER—On some Pycnogonida from the Irish Coasts. 197 
Thompson’s list contains four other species of Mymphon. 
“‘ NV. grossipes, Linn.” is inserted on the authority of Templeton’s 
old list (5) as occurring in the north of Ireland, but what species 
is meant by this it is quite impossible to say. N. Johnston, 
Goods. (6) is recorded from Belfast Bay. This is one of the old 
species which modern writers have failed to recognise. From an 
examination of Goodsir’s figures, I am inclined to regard it as 
identical with NV. grossipes, Fab. (Kr.), which, together with the 
allied species is clearly defined and excellently figured in Sars’ 
recent work (7). It is to be hoped that future investigations of 
our northern coasts may reveal which of the larger Nymphons are 
really to be found there. Another species from Donaghadee 
(10 fms.) is called WV. femoratum, Leach, by Thompson, but the 
identity of this will probably always remain uncertain, as swollen 
thighs (Leach’s specific character) are characteristic of nearly all 
female pyenogons. The fourth species has been recognised by 
Sars, and I therefore insert it in the present list; it is placed, 
together with some other northern Nymphonide, in a special 
genus. 
Genus.—CH#TONYMPHON, Sars. 
Chetonymphon spinosum (Goods.). 
Nymphon spinosum, Goods. 
Thompson records this species from Belfast Bay. Goodsir (6) 
save no locality for his type, but probably took it in the North 
Sea. Sars has found it off the west coast of Norway (7). It 
ranges farther south than any other species of its genus, which 
is characteristic of Arctic seas. 
Family.--PALLENIDZ, 
Genus.—AnorpLopactryLus, Wils. 
Anoplodactylus petiolatus (Kr.). 
This minute but very distinct species 1s represented by a 
single female example dredged by the ‘‘ Harlequin ” (St. 223) 
in Loughrosmore Bay, Co. Donegal, from a sandy bottom, at 
a depth of 4-9 fms. It was first described from the Danish 
seas. Under the name of Pallene pygmea, Hodge (8), it is 
described from Plymouth Sound and the coast of Durham, while
