The Plwxichilm spinosns, Leach, as described and 



figured by Quatrefages (Ann. d. Sc. Nat. 3'*="« s6rie, 



Zool., torn. iv. 184-5) is not a PhoxicMlus at all. 



Perhaps it is a Pallene. 

 PhoxirJiilus meridionalis, Bohm, Pycnogoniden des 



Museums zu Berlin, Monatsber. der Konigl. Akad. der 



Wissensch. zu Berlin, 1879, s. 189, Taf. ii., fig. 4-46. 



A species which stands between P. Iwvis, Grube, and 



P. inermis, Hesse (Bohni). 

 (t) Phnxichiliis inermus, Hesse, Ann. d. Sc. Natur., 5'^™"= 



serie, torn. vii. p. 199, 1867. Perhaps nearly allied to 



P. kevis, 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. 

 Phoxichilus Imns, Grube, Mittheilungen liber St Malo 



und Eoscoff, 1872. During a recent visit to Eoscoil' 



(Bretagne) I collected specimens of this species, which 



is easily distinguished from P. gpinosits, Montagu. 

 (I) Phoxichilus pigmams, Costa (Foxirhibis pignueus), 



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. Iwvis, Grube. Description very insufficient. | 



Pijcnogonum, Briinnich (1764). 



Mandibles and palpi wanting ; ovigerous legs nine-jointed, present only in th 



body, as a rule, robust.
