Genus PUERULUS, Ortraaun, 1897. 



15. Fuerulus carinatus, sp. n. (Plate 16. fig. 5.) 



Caiman (Ann. Mag. Nat. Hist. [8] iii. p. 441) has reduced the genus Puerulus to a 

 single species {angiilatus, Bate), by showing that all the other forms hitherto assigned 

 to it are the young of various species of Panulirus, I am now able to add a second 

 species to the genus on the evidence afforded by an individual taken near Saya de Malha. 

 The following is a diagnosis of the new species : — A Puerulus with the carapace almost 

 smooth save for certain rows of teeth and knobs, almost square save that the back slopes 

 from a keel in the middle ; a furrow on the hinder half of the epistome ; the horns 

 which overhang the eyes wide apart ; just inside each of these horns a smaller horn, 

 cleft at the tip; between the eye-horns and the cervical groove two teeth; in front of 

 the cervical groove four knobs forming a square and in front of the square a small patch 

 of little knobs ; behind the cervical groove four knobs on a middle keel and two side 

 keels bearing knobs on their course and a tooth at their fore end ; below the eye two 

 spines on the edge of the carapace, the upper being the larger, and behind the upper 

 two smaller teeth ; the flagella of the antennule of moderate length, the outer broad and 

 the inner stout ; five teeth on the third joint of the antenna, three on the second joint ; 

 the flagellum of the exopodite of the third maxilliped stout, cylindrical, tapering, 

 reaching the carpopodite of the endopodite ; the legs slender, none (except perhaps the 

 last, which is broken on both sides in the specimen) showing any approach to chelation ; 

 the abdomen smooth, pleura 2-5 bearing two spines, pleuron 6 one spine ; and ou each 

 of the pieces of the tail-fin a small tooth on the outer edge at the junction of the hard 

 and soft parts. 



Length 19 cm. 



One male specimen was dredged in 125 fathoms off Saya de Malha bank.
