The specimen from Makassar, a young female, about 90 mm. long from the frontal 

 margin of the carapace to the end of the telson, which was referred by me (1. c.) in 1892 to 

 Panulirus Burgeri (de Haan) and which is preserved in the Zoological Museum of the University 

 of Amsterdam, is again lying before me. Having compared it with Gruvel's detailed description 

 and excellent figures, it appears to me now quite certain that this specimen must be regarded 

 as a young female of Panul. dasypus (Latr.). It is indeed only by the strong development of 

 the spines on the cephalothorax, which are as plentiful and as well developed as 

 in Panul. Burgeri (de Haan, Fauna Japon. Crustacea, Tab. XLIII and XLIV, fig. 1), that this 

 specimen differs from the descriptions by H. Milne-Edwards and A. Gruvel of Panul. dasypus. 

 There can, in my opinion, be no doubt, however, that this strong spinosity of the carapace be 

 a j u v e n i 1 e feature, for it is also known to occur in other species. 



Of the four outer spines on the antennular tergum the 2 posterior measure two-thirds the 

 length of the 2 anterior and are a little less distant from one another; the four inner spinules 

 are mach smaller, measuring only Ys trie length of the anterior pair. The antennular peduncle 

 extends almost by half the terminal joint beyond that of the outer antennae. 



The legs, long 43 mm., of the i st pair that project by half their dactyli beyond the 

 penultimate article of the outer antennae, are half as long as the body. Though in both species 

 the legs of the 3 rd pair are the longest, in Panul. Burgeri their propodi hardly reach beyond 

 those of the 2 nd pair (de Haan, La), but in Panul. dasypus the 3 vd legs appear, with regard 

 to those of the 2 nd pair, mucli longer, so that in the young female from Makassar the 

 propodi of the 3 rd legs project by one-fifth their length beyond those of the 2 nd pair and 

 the 3 rd legs reach as far forward as the antennular peduncle. The legs of the 5 th pair extend 

 to the midclle of the propodi of the i st ; the lovver margin of their propodi ends in a small 

 acute tooth and the dactylus bears already a small prominence near the articulation on its 

 outer surface, which, when joining the tooth, forms with it a very small chela, beyond which 

 the long rest of the dactylus projects. In all the legs both the upper and the lower margin 

 of the merus terminate distally in au acute tooth. 



On its lower side body and appendages are cream-coloured, and this colour is also 

 presented by the abdominal somites in front of the transverse groove, while posterior to it they 

 are verdigris and marked with numerous, small, round spots. The upper surface of the carapace
