The antennulae are maroon, with a creamy buff mottling at the dis- 

 tal end of each peduncular joint. 



The legs have the first four joints maroon, with a slight greenish 

 cast, longitudinally striated with narrow creamy lines slightly tinted 

 with ochre, the fifth and sixth joints are a rich moss green longitudin- 

 ally striated with narrow creamy lines. 



The first abdominal somite has the anterior part green, mottled with 

 whitish dots, the posterior part maroon, finely punctate, the second 

 to fifth somites, inclusive, are maroon in the median area, shading into 

 deeper maroon posteriorly, the lateral parts are green, the entire 

 surface is finely punctate; a row of minute white dots parallel the 

 posterior margin of each somite. The sides of the somite are maroon- 

 greenish ; there is an enlarged white spot on the median lateral region 

 at the terminal of the epimeral groove ; below these are many spots of 

 creamy buff, including the tips of the segments. The telson has the 

 basal part of the anterior third of the caudal fan green, spotted with 

 creamy buff; the posterior third of the fan is a similar green, the 

 interspace being a lighter green; the caudal fan is margined with 

 bright yellow. All the pleopoda are green, dotted with a few creamy 

 spots and bordered with a bright yellow margin. 



Technical description : Carapace about as long as the abdominal 

 segments, including the anterior third of the caudal fan, covered with 

 stout spines, the more prominent of which are arranged in ten more 

 or less regular longitudinal rows ; spaces between the major spines are 

 almost completely covered with lesser spines, which are broader bas- 

 ally, sharp-tipped and ringed with a circle of close-set, plumose setae ; 

 all the spines are directed upward and forward. The side plates of 

 the carapace are more freely articulate than in P. argus or P. guttatus. 



Orbital spines compressed laterally, but less so than those of Panu- 

 lirus argus or P. guttatus, deeper dorsoventrally, and slightly more 

 elevated than in argus or guttatus. Eyes prominent, shining black. 

 Anterior to the frontal horns there are four long, equal and equally 

 spaced green spines ; between the latter, near the base of the second 

 pair, are several weak spines clothed with setae. There is a convex 

 ridge extending from the base of the orbital spines to the extreme 

 frontal margin; this is much more prominent than in argus or 

 guttatus. 



The antennae have the basal ridge short on the outer dorsal surface, 

 produced and tapering to an acute point on the inner dorsal surface, 

 also on the inner ventral surface ; there is a very strong spine on the
