curved supra-orbital spine. Basal joint of the antennae with a 

 spine at its antero- external angle. First pair of legs slender, as 

 long as the carapace ; second pair more than twice as long as the 

 first ; following pairs shorter than the second. 



This genus is nearly related to Chlorinus aculeatus of Milne- 

 Edwards, C. longispina of De Haan and C. acanthonotus of Adams 

 and White, (which seem to require to be generically separated 

 from C. her os, of Leach) ; it differs from these mainly in the 

 presence of a spine on the basal joint of the antennae, and the 

 much greater length and slenderness of the ambulatory limbs. 



30. Chlorinoides tenuirostris, sp. nov. Plate xxvi., fig. 1. 



Carapace armed in the middle line with a row of four long, 

 pointed spines, of which two are on the gastric region and two 

 on the cardiac ; ten shorter spines or tubercles on the lateral 

 portions of the gastric region ; five more or less prominent spines 

 on the hepatic and pterygostomian regions — one close to the 

 anterior angle of the buccal orifice ; three longer and four shorter 

 spines on the branchial region, a tubercular eminence towards its 

 inner boundary. Rostral cornua slender, acute, two-thirds of the 

 length of the carapace, divergent from their base. Spine at the 

 distal end of the base of the antennae, prominent, sub-acute, 

 directed forwards and outwards ; a compressed blunt spine 

 situated below the orbit, arising from the base of the antennae, 

 in front of the orifice of the green gland and directed downwards 

 and outwards ; another, much shorter, immediately on the outer 

 side of the orifice of the green gland. Anterior legs as long as 

 the carapace, slender, sub-cylindrical; third joint with a small 

 spine at the distal end of its upper surface ; hand very slightly 

 dilated in the male. Second pair nearly two and a-half times as 

 long as the carapace and rostrum ; third joint in this and the 

 following pairs with a prominent acute spine above at the distal 

 extremity. Abdomen tuberculated. Length, including rostrum, 

 about one and a-half inch.
