which locality the species was recorded by the Challenger. The 

 Hawaiian Islands are here added to the records. 



Remarks. — The length of these specimens is in all cases measured 

 from the level of the eye to the end of the telson. The antennal scale 

 has four teeth on the lateral margin in addition to the terminal spine 

 in the small specimen, and five and six teeth in the two larger speci- 

 mens. The rostrum is broken in the two smaller specimens. In the 

 largest specimen it measures 22 mm. from the level of the eye to the 

 tip. The median posterior dorsal spine of the carapace does not ex- 

 tend backward as far as the posterior end of the first abdominal somite 

 and the posterolateral spines of the carapace extend backward as far 

 as the distal end of the second abdominal somite. Ortmann (1906) 

 has given a series of figures illustrating the changes which take place 

 in G. ingrens, in the form of the epimera of the sixth abdominal somite, 

 with growth. The small specimen has the epimera of the form shown 

 in Ortmann's figure 2, c, and the other two specimens as in figure 2, d.
