and the antennular terj^aim is also verdigris, the supra-orbital spines are marbled with cream 

 flecks and the spines of the upper surface are cream-coloured at their base, while those of the 

 antennal peduncle are here blue coloured; the antennular peduncles and the leys, finally, arc- 

 partly verdigris, partly cream-coloured above. 



This specimen, however, certainly presents also a close resemblance to Paiutl. spinosjis 

 (H. M.-Edw.), in which species, according to Bolvikr (in: Bull. Musee Oceanogr. Monaco, 1905, 

 ]). 28) the exopoditc of the 2""^ maxilipeds should extend beyond the base of the carpus, while 

 in Paniil. dasyptis it should hard))- attain the extremity of the merus. In the specimen from 

 Makassar the exopodite reaches indeed a little beyond the distal extremity of the merus, I do 

 not venture, however, to refer it to Pamtl. spiitosus, because two sjMnes occur in the middle 

 line of the gastric region, just in front of the cervical groove and placed behind one another, 

 wliile, according to H. Mh.xk Edwards 1837, the gastric region should bear no spine in the 

 middle line. Gruvel, indeed, seems to have referred the specimen from Pulo Condore to Paiiul. 

 dasypus (1. c. p. 34), while J'aiui/. spinostis is regarded by him with some doubt as a synonym 

 of the West-Indian Paint/, giiffa/iis (Latr.).

Though the identity of this species with Panul. polypliagus (Herbst) has already been 

 acknowledged by H. Balss, in: Ostasiatische Decapoclen II. 1914, jj. 78, the following obser- 

 vations of the type of Paniil. orientalis Doflein will still, I hope, be welcome; I am indebted 

 for them to Dr. Balss, who kindly has enabled me to examine the type preserved in the 

 Zoological Museum at Munich. The examination of this specimen, a \oung male, perhaps from 

 Japan (Bai.ss, 1. c), proved at once its identity with Pamil. polyp/iagus (Herbst), of which I 

 have published a detailed descrijjtion in 1896 (in: Zoolog. Jahrb. Abth. f. Syst. IX, p. 502, 

 Taf. 34, Eig. 59, 59«) after a full-grcnvn female from Singapore. The type, long i 10 mm. 

 from the frontal margin of the carapace to the end of the telson, almost fully agrees with my 

 cited description, not only as regards the morphological characters, but also as regards the 

 characteristic coloration ; it shows, however, some slight differences, owing to its younger age 

 and these differences must be described, because they are still imknown. 



The adult female from .Singapore was 270 mm. long, the carapace 90 mm., and the 

 supra-orbital spines, measured along their uj^per or posterior margin, proved to be 20 mm. 

 long; in the type of Panul. orientalis these numbers are respectively 1 u) mm., 36 mm. and 

 II mm., so that the supra-orbital spines are co m j) a r a t i ve 1 y a little longer than in the 

 ailult specimen. The lateral parts of the gastric region presented in the adult specimen 3 small 

 spines, situated behind one another and the posterior of which was rudimentary, while the 

 gastric region did appear for the rest quite smooth; in Doklk.in's type, however, the posterior 

 one oi the 3 s[Mnes is well-developed, though it is very small, much smaller than the two 

 anterior spines and one observes a 4''' spine between the posterior one of the three and the 

 second submedian spine behind the large supra-orbital one; this 4''' spine is placed somewhat
