 (1) Phoxichilidhmi glohosum, Goodsir, Edin. New Philos.

 probably a female of some species or other. 



Phoxirltiliilium maxillare, Stimpson, Invertebrata of 

 Grand Manan, 37, 1853. P. maxillare, Stimpson, Wil- 

 son, Pycnogonida of New England, Trans. Connect. 

 Acad., vol. V. p. 12, 1880. I never saw this species. 

 Wilson says it resembles P. femoratum of Europe. 

 It has five-jointed ovigerous legs, wanting in the 

 female. 



Phoxkhilidium minor, Wilson, Pycnogonida of New 

 England, Trans. Connect. Acad., v. 13, 1880. 

 Smaller than P. maxillare, to which it is closely allied. 

 It has also five-jointed ovigerous legs, wanting in the 

 female. It may be a dwarf variety of P. maxillare 

 (Wilson).
