peduncle with a strong spine at the distal end of lower margin; 

 other joints of antennal peduncle unarmed. 



Legs of Ist pair resembling those of Gehicula exigua Alcock, 

 but the dactylus impinges against a short, immobile finger; one 

 single spine midway between the acute tip of the index and the 

 carpus on the slightly concave, lower border of the inner surface 

 of the somewhat distorted palm ; upper margin of the palm with 

 five equidistant spines. 



Legs of 5th pair subcheliform ; slightly curved dactylus 3-times 

 as long as the immobile finger. 



Length of single female without eggs 18,5 m.m. 



16. Upogehia {Upogebia) fallax n. sp. 



Stat. Haingsisi, Samau-Island. Depth 36 M. 



Closely related to Upogehia pugnax n. sp. 



Rostrum and carapace about as in this species. Abdomen twice 

 as long as the carapace. Sixth somite longer than broad, almost 

 once and a half as long as the second. Telson somewhat less 

 broad than in Upog. pugnax, not yet half as long as the 6th 

 somite; its posterior margin slightly concave as in Upog. pugnax. 



Exopodite and endopodite of the caudal fan much resembling 

 those of Upog. pugnax, but still longer ; exopodite more than twice 

 as long as the telson, anterior border nearly straight, making an 

 obtuse angle with the distal margin; endopodite shorter than in 

 Upog. pugnax. 



First joint of the antennular peduncle and antepenultimate 

 joint of antennal peduncle with a spine at the distal end of the 

 lower border, as in Upog. pugnax', antepenultimate joint of an- 

 tennal peduncle with a spiniform scaphocerite at the distal end 

 of the upper border; penultimate joint of this peduncle with two 

 equal spines on the lower margin. 



Legs of Ist pair much as in t/po^r. pM^na.r, but the lower border 

 of the not distorted palm with two small spines proximally. Dac- 

 tylus 5-times as long as the immobile finger, its upper margin 

 finely denticulate.
