The specimen from Stat. 209 is 27 mm. lonij and resembles the last mentioned, the 

 shallow grooves on tlie 2"'' and 3'^ terga of the abdomen are, however, already present. 



The 4 specimens from Stat. 258, all 24 mm. long, agree also with the last mentioned 

 specimens [^Pamilirns dcmaiii) and in some of them traces of the transverse grooves are already 

 discernible; the outer antennae are a^.^-times as long as the body. 



The male from Goenocng Sitoli, Nias, is 31 mm. long, the ground-colour is a pale 

 brown ; on the carapace the whitish W-shaped figure is visible, like also the whitish transverse 

 band near the posterior margin of the abdominal somites. The interrupted transverse grooves 

 on the 2"^^ and 3''<^ abdominal somites arc discernible. 



The two other specimens from Xias are 22^., nim. and 23'/, mm. long. In these three 

 specimens from Nias the anterior pair of spines on the antcnnular segment are well-developed, 

 those of the posterior pair, however, are in the male, long 31 mm., very short; in the individual, 

 long 2 2^., mm., the spinules of the jjosterior pair are rudimentary and in the specimen, long 

 23^.-, mm., even wanting at all. Also in some of the very young specimens from the other Stations, 

 that are shorter than 25 mm., the two posterior spines are often rudimentary or wanting.

Though this form is considered by Dr. Calman and, as I think, rightly, to be the 

 "Xatant-stage" of Panulirzis versicolor (Latr.), the following remarks will i)robabIy be welcome. 



The specimens are nearly all of the same size, the largest are 24 mm. long, measured 

 in the middle line from the anterior margin of the carapace to the end of the telson. In the 

 largest individuals the carapace is 9 muL long, the abdomen 15 mm.; both are smooth, though
