This female is 26 mm. loni^j from tip of rostrum to tip of telson and proves thus to 

 be half-grown, for of this species the male and the female attain respectively a length of 40 mm. 

 and 44 mm. (J. G. dk M.\n, G. Nokili, locis citatis); it fully agrees with the younger specimens 

 from Ternate, described by me in 1902. The rostrum that reaches to beyond the middle of 

 2°'^ antennular article, is f-dentate, two teeth stand on the carapace, the third above the orbital 

 margin with the tip situated a little in front of it; tooth of the lower border placed just below 

 the anterior tooth of the upper. The telson (Fig. 49), 3 mm. long, measures about '/» the entire 

 length, the width, anteriorly, 1,8 mm., is a little more than half the length and in proportion 

 to the width, 0,64 mm., of the tip like i :o,36: the dorso-lateral spinules are rather large, the 

 anterior 0,6 mm. long, one-fitlh the length of the telson, the posterior 0,5 mm. long; the 

 telson terminates in a sharp spine, on either side of which two spines are implanted, of which 

 the lonijer inner one measures one-third the entire lenoth of the telson, the outer one two-fifths 

 the inner. Uropods considerably longer than telson. 



According to Nobili the pleopods of the adult, ova-bearing female are "elargies, foliacees, 

 membraneuses, amples, analogues (mais de forme ovalaire et moins larges) au.\ expansions 

 membraneuses des antennules et des maxillipedes". In the present female they have the usual 

 laticeolate shape; the exopodite of the 2"'' pleopod is 3 mm. long, 5-times as long as broad, 

 appearing rather narrow, the inner branch, which is hardly shorter, 6-times as long as broad; 

 stylamblys with well-developed cincinnuli at the tip,- 0,8 mm. long, two-sevenths the length of 

 the inner branch, and implanted, as usual, at the proximal third of the outer margin. 



This species will perhaps prove to be identical with Hymenocera Latreillii Guer. oi 

 the Seychelles, mentioned at p. 191.

I'"amily Processidae. 

 Nikoides 1'aul.son. 



The genus Nikoides Paulson, distinguished from Pi'occssa Leach by the i"' pair of perae- 

 opods being furnished with a well-developed exopodite, comprises four species. One of them, 

 Nik. potitica Sowinsky, is found in the Black Sea. Nik. Danac Paulson, the first described 

 species, occurs in the Red Sea and is known from Djibouti, Perim and the Kamaran Islands. 

 A third closely related form, Nik. vialdivensis Borr., has been recorded from the Maldives 

 and the Amirante Islands. The fourth species, finally, Nik. Sibogac, was captured by the 

 "Siboga" off Makassar, at the east coast of the Aru-islands and between Xusa Besi and the 

 \.?L. -point of Timor. 



The species of Nikoides occur in shallow water. Nik. Panae was found at I )jib()uti at 

 a depth of 11 fathoms, Nik. Sibogac at 50, at 31, between 15 and 30 and up to 17 lathoms.
