SUPPLEMENTAL NOTES. 



ALLORCHESTES NILSSONII. 



(Vol. I. p. 40.) 



The females of this species, and probably of all in the genus, 

 have the second pair of gnathopoda, slightly larger than 

 those of the first pair. 



Genus- MONTAGUA. 



(Vol. I. p. 53.) 



Dr. Camil Heller (Beitrage zur naheren Kenntniss der 

 Amphipoden des Adriatischen Meeres ; Denkschr. Ak. Wiss. 

 Wien, xxvi. p. 13) states that this genus is identical with 

 Probolium of Costa. 



PHOXUS HOLBOLLT. 



( Vol I. p. 143.) 



Mr. Edward has sent us from Banff a specimen that cor- 

 responds with this species, except in having longer inferior 

 antennae. 



We consider it the male form. 



PHOXUS PLUMOSUS. 



(Vol. I. p. 14C.) 



A specimen of this genus has been forwarded to us from 

 Banff, by Mr. Edward, that corresponds with this species in 

 general character, except in having very much longer lower 

 antennas, as well as a long plumose posterior pair of pleopoda. 



We take it to be the male form.
