Name. 



* Phoxichilidlum patagonieum, n. sp. A beautiful species. 

 It was dredged at different stations in the neighbour- 

 hood of the Patagonian coast. 



*PhoxichiUdiu')n patagonieum, var. elegans, Hoek. 

 Whether this is a true variety of the preceding species, 

 or is only to be considered as a young specimen of this 

 species, I am unable to ascertain. 

 Plioxiehiiidium cligitatum, Bohm, Pycnogoniden des 

 Museums zu Berlin, Monatsber. der K. Akad. der Wiss. 

 in Berlin, 184, 1879. Perhaps nearly allied to my 

 P. patagimicum (ovigerous legs occurring only in the 

 males. Number of joints ?) 

 (I) Phoxichilidlum pygmceum, Hodge (sp.). Pallene 

 pygmcea, Hodge, British Pycnogonoidea, Ann. and 

 Mag. of Nat. Hist., 3d series, vol. xiii., 1864. As 

 far as I could ascertain from the extremely insuffi- 

 cient description of Hodge, and from his figures, 

 this species belongs to the genus Phoxichilidium. 

 One of the species of Phoxichilidium occurring on the 

 French and on the Dutch coast is probably the same 

 species. Should this prove to be true the ovi- 

 gerous leg is six-jointed and occurs only in the 

 male. 

 Phoxichilidium virescens, Hodge, British Pycnogonoidea, 

 Ann. and Mag. of Nat. Hist., 3d series, vol. xiii., 1864. 

 Description insufficient. As far as I could make out 

 it is one of the more common forms of the Dutch and 

 French coast. (Ovigerous legs wanting in the female, 

 six-jointed.) 

 Phoxichilidium lentitm, "Wilson (sp.). Anoplodactylus 

 lentils, Wilson, Pycnogonida of New England, Trans. 

 Connect. Acad, of Arts and Sc, vol. v. p. 14, 1880. 

 Wilson gives this name to the species described by 

 Smith (Report Invertebrata of Vineyard Sound, p. 250) 

 as Phoxichilidium maxillare. I think it is closely 

 allied to Phoxichilidium virescens, Hodge (Ann. and 

 Mag., 3d. ser., vol. xiii. p. 115, 1864). Ovigerous legs 

 only in the male, six-jointed. 



* Phoxichilidium oscitans, n. sp. A very curious deep-sea 



species, easily to be recognised. 



* Phoxichilidium pilosum, n. sp. A beautiful deep-sea 



species. 



* Phoxichilidium mollissimum, n. sp. Unfortunately only 

 a defective specimen of this curious form was dredged 

 by the Challenger Expedition. It has ten-jointed 

 ovigerous legs.
