Decapod Crustacea of Bermuda, Part II. 17 



O. antlgiKc Stabbing also occurs on the oral appendages of a 

 species of the family Palinurida: in the West Indies. 



O. forrcsti Stebbing has been found in the gill cavity of a 

 Palinurid from Florida Keys (perhaps P. argus). It is a smaller 

 and much less calcified species.

PLATE IX, FIGURE 2. Stridulating organ. 



.Mr. Louis Mowbray informed me, by letter, that he had obtained 

 this species at Bermuda. Personally, I have seen no Bermuda 

 specimens of it. It has a very spiny carapace, and two large 

 conical spines on the antennular segment. Carapace is thickly 

 covered with conical spines, much more numerous than in A. argus. 

 The two large "rostral horns" are stouter, but not so long as in 

 the latter and each has a conical spine behind its base. There is 

 a strong conical spine on the anterior margin below the orbits. 

 The large antennae are much more slender than in A. argus; the 

 proximal part of the flagellum is only about half as thick. 



Its back is greenish with very numerous small round yellow 

 spots ; the propodus of the legs is longitudinally striped with green 

 and yellow. 



Its range extends through the West Indies to St. Paul's Rock. 

 (Bate, as a variety.) Bate also records it from the Isle of France 

 and New Holland (var.). 



The "variety" described and figured by Bate from St. Paul's 

 Rocks may be a distinct species. It seems to agree very nearly 

 with P. cchinatus Smith, from the Brazilian Coast. 



Bate has figured (his PL XA, fig. c), a well formed Stridulating 

 organ on the base of the antennal peduncle. (See pi. ix, fig. 2.) 



OF PANULIRUS; Phyllosoma. 



The Phyllosoma-form larva, of which three stages are shown on 

 Plates 3, 3 A, is thought to be the larva of this species, chiefly 

 because it is the most abundant species of the group and extends
