21. Callianassa (Clieramus) moluccensis u. sp. 

 Station Ambou, reef. -^ 



One single male was coUected, the legs of the Ist and of the 

 4th pair are wauting. Apart from these legs, this species resembles 

 most closely Call. indica n. sp., but it dififers especially by the 

 different shape of the eyepeduncles and of the abdominal appen- 

 dages of the Ist somite. 



Median rostral tooth a little longer and sharper, the lateral 

 teeth very small and rounded. Telson a little broader in propor- 

 tion to its length, resembling still more that of Call. mauritiana 

 Miers, caudal swimmerets reaching beyond the telson, when di- 

 reeted backward; a small spinule at the base of the posterior rib 

 of the exopodite. 



The eyeplates that are different from those of Call. mauritiana 

 Miers and Call. Filholi A. M-Edw., do not yet reach to the distal 

 end of the Ist joint of the antennular peduncle; they are very 

 little — one sixth — longer than broad at their base. The inner 

 margins that are unarmed, diverge gradually from the tip of the 

 median rostral tooth foreward and then curve ontward to an 

 antero-external angle which is rather sharp and slightly turned 

 upward and ontward. Eye convex, situated on the outer margin 

 of the plate, but larger than in Call. indica^ distinctly facetted 

 and black pigmented, situated as far from the proximal end of 

 the outer margin as the eye is long, but a little farther from 

 the antero-external angle. Upper surface of the peduncle sloping 

 obliquely down in a a lateral view, as in Call. indica. 



Abdominal appendages of the Ist pair as in Call. indica., but 

 of the two lobes into which they end distally, the inner one is 

 obtuse, the outer, however, hookshaped, the hook being acute, 

 reaching beyond the inner lobe and curved inward. 



Length 60 m.m., carapace 16'/^ m.m. loug.
