142 STALK-EYED CRUSTACEA. 
This species, which was captured near the shores of the Galapagos 
Islands, is comparable with G. aculeata A. M. Edw., G. regalis Bate, G. in- 
vestigatoris W.-M., and G. smithii W.-M. It differs from all of these in having 
three pairs of rostral spines in front of the gastro-frontal sulcus, and in the 
length, slenderness, and strong outward trend of the hepatic spines. It dif- 
fers furthermore from G. aculeata and G. investigatoris in being much more 
lightly tuberculated ; from G. aculeata and G. smith in lacking the spine at 
anterior end of the third carapacial carina, behind the cervical groove ; from 
all of the above-named species, except G. ivestigatoris, in the spiny arma- 
ture of the telson.

Of Glyphocrangon nobilis A. M. Edw., I have only small, immature speci- 
mens before me, and I am not sure that the “ Albatross” specimens here 
referred to this species are really the same. In any event they are very 
closely allied. In typical specimens of the “ Albatross” species, the distance 
from the tip of the rostrum to the small tubercle that lies in the median dorsal 
line at the anterior boundary of the gastric region is equal to the distance of 
this tubercle from the posterior margin of the carapace, measured along the 
median dorsal line. But the length of the rostrum varies to a considerable 
degree in different specimens. When it attains its maximum length, the dis- 
tance from the tip to the basal lateral spines alone equals the length of the 
rest of the carapace, measured along the median line. The margins are 
thickened and concave between the two pairs of lateral spines. A median
