of back with the distal ends of joints orange-red. Legs with tubercles, ridges 

 and extremities bright orange-red, relieved by a depressed ground colour, like 

 back, on the sides ; inner portion of penultimate joint, and of all the others, 

 except the terminal and antepenultimate joint of anterior leg, whitish ; sternum 

 and basal joint of other legs whitish on tubercles and prominent parts, with a purplish 

 colour, like back, as ground colour on depressed portions. Abdomen same purple- 

 madder colour as carapace, with the lateral spines tipped with bright orange red ; 

 tail fins dull orange in middle, with longitudinal rows of tubercles and margins of 

 purple-madder of back, becoming darker at distal end ; narrow lateral ridge and 

 points of tubercles on lateral edges orange-red. Measurements : Total length from 

 tip of snout to end of tail flaps, 1 ft. 6 in. Proportional measurements to total 

 length, as 100 : — Length of thorax, y^ ; length from thorax to penultimate joint of 

 abdomen, -j^j; greatest width of thorax, -j^ ; depth of thorax, -^-^ , greatest width 



1 .5 



of abdomen, -^7; length of telson, xwo', greatest width of telson near end, - ] 

 length of first three joints of outer antennse, ^o', width of ditto, -j-J^- ; length of 

 flagella of outer antennae, ^m, length of rostrum, T f^ ; length of supraorbital 

 spines, x^; length of first joint of inner antennas, -j 1 ^; second joint, -j^; third 

 joint, ■^ T ; flagella, y^ ; length of first pair of legs, -^; second pair, -£^; third 

 pair, -3^5-; fourth pair, ^£5-; fifth pair, ^ u ; greatest width of first leg (at middle 

 of penultimate joint), -j^j. Female : The last pair of legs subchelate by the large 

 conical upcurved spine on lower margin of anterior edge ; the spines on lower 

 surface of joints of anterior pair of legs are smaller than in the male of same size, 

 especially those on the penultimate joint ; the rostrum is also a little smaller than in 

 the male, which it otherwise resembles.

This fine and very interesting species has not been properly 

 figured before, and is consequently a source of some perplexity to 

 naturalists. It was first described from the Cape of Good Hope 

 by Prof. Milne Edwards, from the specimens in the Paris Museum 

 named in manuscript P. Lalandi by Lamarck ; and, many years 

 ago, the late Dr. Gray and Mr. Adam White in their "List," 

 published in 1847, referred two specimens in the British Museum 

 to it, one from New Zealand and one from S. Africa. Capt. Hutton 

 subsequently described the New Zealand Palinurus under the name 

 of P. Edwardsi, distinguishing it from P. Lalandi by its smaller 

 size (9^ in.), by the upcurved beak (said by him to be straight and 

 conical in P. Lalandi), in having no spine on the penultimate joint 

 of the anterior legs, and in having a second small spine at the distal 

 extremity of the third joint of the last four pairs of legs. In the 

 female of P. Edwardsi the rostrum is said by Prof. Hutton to be 

 wanting.
