Family PALINURIDAE. 



The Palinuridae, collected by the "Siboga", belong to the genera Puerulus Ortm. and 

 Panulirus White, the former represented by Puerulus angulatus (Sp. Bate), of which no less 

 than 28 mostly adult specimens were captured, both males and females, from two Stations; 

 the latter represented by two species, Panitl. ornatus (Fabr.) and Panul. versicolor (Latr.). Of 

 the last mentioned species 1 3 very young specimens were moreover obtained, that belong to 

 the p uerulus- or "Natant"-stage, from four Stations, and 2 of these 13 specimens were collected 

 together with young individuals of Panul. versicolor. The descriptions of a few, most adult 

 specimens of Panul penicillatus (Oliv.), collected by Messr. Kleiweg de Zwaan and E. Jacobson, 

 like also of a young female of Panul. japonicus (von Siebold), obtained by Mr. G. F. Tydeman, 

 are added, and also critical remarks and observations on some other species and varieties of 

 the crenus Panulirus White.
