latter: Fingers 1; total length 2,44; height 0,81 ; fiugers tapering. 



First carpal segment of 2nd pair as long as the sum of the 

 four following and a little longer thau the chela. 



Relative diraensions of 3rd pair: Meropodite 2,23; carpus 1; 

 propodite 2,05. Meropodite unarmed, 3,66 tiraes longer than wide, 

 propodite 6 times longer than wide, with 6 spinules. Dactylus 

 3 times longer thau broad, its leugth one fourth that of the 

 propodite (when measured to extremity of ventral hook); dorsal 

 hook twice as long, but just as broad at its base as the ventral, 

 angle between both hooka acute. 



Ova uot numerous, large, 0,95 rara. long. Length of single

5. Synalpheus gracilirostris, n. sp. 



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

 betweeu Nusa Besi and the N.B. point of Timor. Depth 

 27—54 M. 



A new species of the Paulsoni-grouTp, closely related to St/h. 

 hululensis Cout. and to Syn. Mac-Cullochi Cout. 



Rostrum sleuder, 8 or 9 times as long as wide iu the middle, 

 exteudiug to the 2nd third part of raedian antennular article ; 

 lateral spines also slender, but two fifths shorter than the rostrura. 

 iVntennular peduncle 4 tiraes as long as thick, the relative propor- 

 tious of the three articles are as 8:5:5; 2nd article slightly 

 longer than thick at distal extreraity. Stylocerite as iu Syn. hulu- 

 lensis. Lateral spine of basicerite rather stout, as long as the 

 basal portion and reaching as far foreward as Ist article; upper 

 angle subacute, but with no spine. Carpocerite 3,75 — 3,8 times 

 as long as wide, hardly surpassing the antenuule, terminal spine 

 just exceeding the carpocerite, for the rest the scaphocerite as iu 

 Syn. hululensis. Telsou 2,34 — 3 tiraes as long as the posterior 

 margin is wide, the latter as in Syn. huhdensis, but the median 

 part more prominent, almost semicircular. 



First pair of legs as in that species, but the tapering fingers 

 of the smaller chela are shorter, the relative diraensions being:
