I not succeed in identifying these specimens with any one of the described species, they 

 may even perhaps prove to belong to three or four different forms. The largest specimen, that 

 from Stat. 193, is 21,5 mm. long, but the three posterior peraeopods are wanting or incomplete; 

 the other specimens are considerably smaller, though one of them is laden with eggs. The 

 specimens not fully agree in some minute details, as e. g. the shape of the carpal segments 

 of the legs of the 2"'^' pair, the position of the dorso-lateral spinules on the telson etc., so that 

 under these circumstances it appears more adequate to describe these specimens without referring 

 them to a known species. 1 )r. Halss rightly remarks that a revision of the species oi Processa is 

 very desirable (Ostasiatische Decapoden II, 1914, p. 60). 



The female from .Stat. 193 is 21,5 mm. long (rostrum 1,64 mm., carapace 4,92 mm., 

 abdomen with telson 15 mm.). The greate.st height laterally of the carapace is 2,85 mm., so 

 that the carapace, rostrum included, proves to be 2Y3-times as long as high. The rostrum, 

 (Fig. 52, 52^, 52(5), almost as long as the eyes, extends horizontally forward, but the acute 

 ape.K of the upper margin is slightly curved downward; the acute .spine or tooth at the end 

 of the lower border reaches a little farther forward than the apex of the upper and in the 

 notch between both teeth a few setae are implanted; looked at from above tlie rostrum appears 

 styliform, gradually tapering forward from the slightly wider base, and in a lateral view it 

 appears also rather low, decreasing in height distaliy. 



Outer orbital angle rounded. Antennal spine well-developed. Antero-inferior angle of 

 carapace rounded. Carapace smooth, 3-times as long as the rostrum. 



The abdomen, also smooth, is nearly 3-times as long as the carapace without the rostrum. 

 Abdominal pleura rounded, that of the 5''' somite entire, not toothed, postero-inferior 

 angle of the 6''' somite acute. The telson, 3 mm. long, (Fig. 52^, 52^/, 52^) measures one-hfth 

 the whole length of the abdomen and is about half as long as carapace and rostrr.m combined ; 

 it tapers rather strongly, the width of the tip being only one-third that of the base, and it is 

 slightly grooved longitudinally; dorso-lateral spinules large, the anterior pair at '/- the length 

 of the telson from the base, the posterior pair on the middle; of the 2 terminal spines, at either 

 side of the .subacute apex, the inner one is the longe.st, 3-times as long as the lateral, and between 

 the two long spines two finely and closely feathered setae are implanted that are nearly just as long. 



Eyes large, flattened; a small dark-coloured ocellus, that occurs in a species from the 

 Hawaiian Islands, referred by Miss Rai iii?ux to Proccssa processa (Bate), could not be observed 

 (.M.J. Ratiii!LX, I'he Brachyura and Macrura of the Hawaiian Islands, 1906, p. 912). 



.Anlennular peduncle slender, basal joint a little longer than the two following taken 

 together; 2'"' joint 3-times as long as thick and twice as long as 3'''. A stvlocerite does not occur.
