antennular article and the corneae are comparatively larger, reaching backward as far as the 

 tip of the rostrum. The median, antennular article appears hardly one and a half as long as 

 the visible part of the first and 3-times as long as the third ; the scaphocerite reaches almost 

 to the end of median article. 



As regards the frontal and antennal region, the specimen, long 12 mm., from Ambon 

 agrees with that from the Station 86. It is difficult to say whether the described differences 

 exhibited by the specimens from the Stations 86 and 181 are due to a difference of age, or 

 that these specimens belong to another species than those from Stat. 19. Compare also the 

 measurements in the Tables A and B.

Stat. 114. July 8. o°58'.5N., 122° 55' E. Entrance of Kwandang-bay. 75 m. Hard sand, very 



fine. I mutilated specimen, probably a female. 

 Stat. 193. September 13/14. Sanana-bay, East coast of Sula Besi. 22 m. Mud. i mutilated 



specimen. 



Rostrum acute, very small, its length one-fifth that of the eye-peduncles, the latter as 

 in the other species of this genus; corneae almost extending to the middle of the peduncles, 

 that are obtusely pointed at the tips. The eye-peduncles are a little shorter than the visible 

 part of the basal antennular article, the proportion being as 7:10. 



Antennular peduncle rather slender; median article 3-times as long as thick in the middle, 

 one-fourth longer than the visible part of basal article and 2, 5 -times as long as the third, the 

 visible part of basal article and the two following being in proportion to one another as 4 : 5 : 2. 

 The inner margin of the basal article has a small spine a litde in front of the eyes, just 

 at the angle where the margin is turned outward; several stiff setae are observed at the apex 

 of the basal and of the median article. Stylocerite acuminate, a little shorter than basal article.
