pentagonal mark in the centre, the apex prolonged to the 

 front, which it divides. Area on each side of the mouth below 

 with monilitbrm transverse stria\ Arms trigonal, striated on 

 the outside ; hands smooth outside, and with a few scattered 

 granules inside ; fingers smooth. Legs with the third joint 

 verj broad, compressed, acute above, and armed with a single 

 tooth at the apex, smooth ; outer joints and claws tomentose. 

 Length "67 inch ; ratio of length to breadth 1 : 1'27. 



A single specimen in the Colonial Museum, Wellington, 

 locality not stated. 



Palinurus Edwardsii. 



Male. Carapace beaked, armed with spines and large oval 

 depressed tubercles separated by rows of short hairs. Beak 

 small, compressed, curved upward, and with two small spines 

 at its base ; spines on each side of the beak compressed and 

 smooth. Abdomen transversely sulcated, and covered with 

 tlat tubercles, each segment with a row* of short hairs on its 

 posterior margin ; a single tooth on the |K)Sterior margin of 

 the lateral lobes of the abdominal segments. Anterior legs 

 with a strong spine on the inferior margin of the second and 

 third joints, none on the penultimate joint ; the superior 

 margin of the distal extremity of the third joint of the last 

 four pairs of legs armed with two spines, a smaller one in 

 front of the larger. Length from beak to end of telson 

 9*5 inches. 



Colour. Carapace and antennge dark brownish purple ; 

 abdomen the same, marbled with yellow ; legs and caudal 

 appendages reddish orange, more or less marked with purple. 



In the female the beak is wanting, and there is a spine on 

 the inferior margin of the distal extremity of the penultimate 

 joint of tlie last pair of legs, making it subchelate. 



Locality. Otago Heads, common. 



This species differs from P. Lalandii in its much smaller 

 size, in the shape of the beak (which is straight and conical 

 in P. Lalandii), 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. I have named it in honour of M. Alphonse Milne- 

 Edwards, who has done so much to increase our knowledge 

 of New-Zealand carcinology.
