Mr. E. J. Miers on Malaysian Crustacea. 379 



Museum collection, the greenish or bluish rings on the ambu- 

 latory legs are much interrupted, so that the legs appear to 

 be irregularly spotted or marbled rather than annulated. 



Palinurus (Panulirus) penicillatus (Olivier). 

 Indo-Malayan seas (a female of small size, without locality). 



Palinurus (Panulirus) versicolor (Latr.). 



Aroe (Aru?) Islands (a young male, in which the colora- 

 tion is excellently preserved). A young male from Samang- 

 kabaai, and two others without definite locality, in the collec- 

 tion, probably belong to this species. When the character- 

 istic coloration has disappeared, it is extremely difficult to 

 distinguish young examples of this species from P. ornatus. 

 In the adult P. ornatus the spines of the carapace, especially 

 on the branchial regions, appear to be more numerous than in 

 P. versicolor. 



Palinurus* (Panulirus) longipes, A. M. -Edwards. 



As the specimen before me differs in some particulars from 

 M. -Edwards's description, 1 subjoin the following : — Carapace 

 covered with spines interspersed with numerous smaller 

 spinules or spinuliform tubercles ; none but the smaller 

 spinules on the sides of the branchial regions of the carapace. 

 Upper surface of the antennal segment covered with spines 

 disposed as follows : — two long spines placed somewhat in 

 front of the middle of the segment ; anterior to these, four 

 small median spinules in a transverse series ; and posterior to 

 them, six disposed in a semicircle. There are usually indi- 

 cations of several yet smaller spinuliform tubercles on the 

 posterior part of the segment ; of those above mentioned, all 

 are not always equally developed. 



The dorsal surface of the postabdominal segments is marked 

 with a transverse uninterrupted sulcus ; their lateral prolonga- 

 tions terminate each in a long spine ; the lateral spines of the 



* The British Museum has recently obtained by purchase a specimen 

 of Palinurus from Sydney Harbour, New S. Wales, that I refer to the rare 

 P. Hiigeli, Heller, which is covered by numerous examples of a species 

 of pedunculated Cirripede which I refer to the species long ago figured 

 by Quoy and Gaimard (Voy. Astrolabe, pi. xciii. fig. 5, 1834), and desig- 

 nated by Darwin (from the figure only) as Alepas tubulosu. So far as I 

 am aware, this species has never been observed since the time of its dis- 

 covery. As Darwin supposes, it may be distinguished from its congeners 

 by the smooth, entire, carinated edge of the capitulum. The orifice, 

 although tubular, is less protuberant than in the specimen figured by 

 Quoy and Gaimard.
