Phowxichilus, Latr, (1816). 
Mandibles and palpi wanting; ovigerous legs, seven-jointed, present only in the males ; 
body, as a rule, slender, :

The Phowichilus spinosus, Leach, as described and 
figured by Quatrefages (Ann. d. Se. Nat., 3°™° série, 
Zool., tom. iv. 1845) is not a Phoxichilus at all. 
Perhaps it is a Pallene.

A species which stands between P. levis, Grube, and 
P. inermis, Hesse (Bohm). ‘ 
(2) ()Phoxichilus inermis, Hesse, Ann, d. Sc. Natur., 5°™° | French Coast or Mediter- 
série, tom. vii. p. 199, 1867. Perhaps nearly allied to ranean (1). 
P. levis, Grube. Judging from Hesse’s description, this 
species is furnished with a three-jointed abdomen, and 
this is not the case with Grube’s species, nor perhaps 
with any species of the Pycnogonida. It was taken 
at Brest on the keel of a ship returning from the 
Mediterranean. 
Shore. Phoxichilus lewis, Grube, Mittheilungen iiber St Malo | French Coast. 
und Roscoff, 1872. During a recent visit to Roscoff 
(Bretagne) I collected specimens of this species, which 
is easily distinguished from P. spinosus, Montagu. 
(2) ()Phoaichilus pigmeus, Costa (Fowichilus pigmeus), | Gulf of Naples. 
Fauna del Regno di Napoli, Napoli, 1836, p. 10. 
This species, characterised by its smallness and by the 
absence of the spines at the end of the joints of the 
legs, is perhaps identical with P. inermis, Hesse, or 
P. levis, Grube. Description very insufficient, 
Pyenogonum, Briinnich (1764). 
Mandibles and palpi wanting ; ovigerous legs nine-jointed, present only in the males ; 
body, as a rule, robust.
