terminal spine of the scaphocerite is not curved inward and 

 projects by one fifth of its lengih beyond the rounded tip of the scale. 



Larger chela of female a little longer than the carapace, re- 

 sembling that of Syn. consobrinus, 3,17-times as long as high, 

 fingers a little less than half the length of the chela, similar to 

 those of Syn. consobrinus, hut the distal lobe on the inner (upper) 

 side of the immobile finger, which lobe is rounded in Syn. con- 

 sobrinus and in the other species of this group, is produeed, in 

 Syn. odontophorus, into an acute prominent tooth, directed obliquely 

 upward, and the distal half of the finger is much widened, ap- 

 pearing excavate, when the fingers are looked at from the tips. 

 Fingers of small chela half as long as the palm. 



First carpal segment of 2nd legs slender, a little shorter than 

 the four following taken together. Meropodite of 3rd legs 5,5-times 

 longer than wide, with a rather small, apical tooth, apical tooth 

 of 4th legs still smaller, meropodite of 5th legs unarmed ; pro- 

 podite of 3rd legs twice as long as the carpus, almost 7-times 

 longer than wide, with 16 spinules, dactylus as in Syn. Stimpsonii 

 (1. c. Fig. 3c), one fifth of the propodite. 



Eggs few in number, ovoid, of large size, 0,7 — 1 m.m. long. 



Length of ova hearing female 15 m.m. 



17. Synalpheus streptodactyloides, n. sp. 



Station 282. Lat. 8° 25'. 2 S., long. 127° 18'. 4 E. Anchorage be- 

 tween Nusa Besi and the N. E. point of Timor. Depth 27 — 54 M. 



A new species of the Neomeris group, closely allied to Syn. 

 streptodactylus Cout. 



Rostrum wider than that of Syn. streptodactylus, 2,2 times as 

 long as wide at its base, in Syn. streptodactylus 2,75 — 3,25, 

 usually 3-times, and extending to the distal sixth of basal joint; 

 different from Syn. streptodactylus^ Syn. Neomeris, Syn. Gravieri and 

 other species, the concave, anterior wall of the carapace, below the 

 rostrum, and at either side of it, is not visible at all, and the 

 supraorbital spines tliat hardly reach beyond the middle of basal
