Eggs in most specimens 0,6 — 1 m.m. long, in specimens from 

 Station 310 attaiuing, however, a length of 1,5 — 1,7 m.m. and 

 here few in number. 



23. Sjualpheus nilaudensis Coat., var. bandaensis u. 



Station 49a. Lat. 8° 23'. 5 S., long. 119° 4'. 6 E. Sapeh-strait. 



Depth 70 M. 



Station 240. Banda. Depth from 9—36 M. 



Differs from the typical species by the different shape of the 

 dactyli of the three posterior legs. 



Rostrum, supraorbital spines, antennal and antennular peduncles 

 as in the typical species, but the terminal spine of the scapho- 

 cerite, though longer than the antennular peduncle, does not yet 

 reach to the tip of the carpocerite. Larger chela resembling 

 that of Syn. Neomeris, but the fingers are shorter, measuring 

 oue third of the palm. Upper border of the palm of smaller 

 chela more regularly curved than in the typical form. 



As regards the relative length of mero-, carpo-, and propodite 

 of 3rd legs, this variety agrees with the typical species, but the 

 dactylus has a less stout shape, being 2,5 — 3-times as long, from 

 the base to the extremity of the dorsal hook, as wide near the 

 articulation ; the principal hook is directed obliquely foreward, 

 making no right angle with the anterior margin and the dorsal 

 hook is longer, measuring two thirds of the principal hook. 



Fourth legs similar to the 3rd, but the propodite hardly shorter 

 than the meropodite; in the specimen from Station 49a the pro- 

 podite is even slightly longer than the meropodite. 



Eggs not very numerous, large, ovoid, 0,8 m.m. long. 



Length of ova-bearing female 14 m.m. 



24. Synalpheus fossor Paulson, var. propiuqua n. 



Station 96. South-east side of Pearl-bank. Sulu-archipelago. 



Depth 15 M. 



Station 164. Lat. T 42'. 5 S., long. 130° 47'. 5 E. Depth 32 M.
