BRACHYURA FROM TORRES STRAITS. 41 



M. superciliosa from Torres States (Pr. Linn. Soc. N. S. Wales, iv. p. 446, pi. xxvi. fig. 2, 

 1879), which is ranked by Alcock as a synonym of this variable and widely distributed 

 species.

Our three specimens (2 s , 1 2 ) agree closely with Haswell's description of his 

 T. spinirostris (which De Man regards as synonymous witli Dana's species), save that in 

 the female specimen there are four spines instead of three on the outer margin of each of 

 the rostral horns. De Man figures a specimen with four spines on one side and three on 

 the other, and he describes also a female specimen witli only two spines on each side. 

 The carapace of our largest (femalej specimen measures 45 mm. in length by 27 mm. in 

 breadtli. De Man's largest specimen was 27 mm. long and 14-5 mm. wide. Dana's 

 specimen was only 6 lines long and 2\ lines wide. Haswell gives no dimensions.

Lambrus (Aulacolambrtjs) hoplonotus, Adams & White, var. ? 



Lambnis hojAonutus, Adams & Wbite, Voy. ' Samaraug,' Crust, p. 35, pi. vii. fig. 3; Miers, Aun. Mag. 

 Nat. Hist. (5) iv. p. 22 (1879) ; Miers, Rep. Voy. ' Challeuger,' Bracbyura, p. 98 ; Alcock, 

 Journ. Asiatic Soc. Bengal, Ixiv. (2) p. 273 (1895). 



A male specimen, 9 mm. in length, is probably to be referred to " this protean species," 

 as Miers calls it. It differs considerably from the figm*e of Adams and White, the whole 

 anterior part of the carapace being much narrower and more produced, and the rostrum 

 projecting well in front of the orbits. There is a slight jiostorbital constriction, followed 

 by a sharp hepatic tooth, which is longer than the succeeding spiniform teeth of the 

 lateral margins. The granules on the surface of the carajjace are acute and spiniform. 

 Our specimen agrees pretty closely with some referred by Mr. Miers to his variety 

 longioculis, which " is best distinguishable by the subspiniform tubercles of the branchial 

 regions" ('Challenger' Bracbyura, p. 99), the greater jjrotrusion of the eyes being, I 

 believe, quite an accidental circumstance. 



Locality. " Torres Straits." 



Lambrus (Parthenolambrus) calappoides, Adams & White. 



Parthenope calappoides, Adams & White, Re]). Voy. ' Samaraug,' Crust, p. 3-1, pi. v. fig. 5. 



Lambrus [Parthenolambrus) calappoides, Alcock, Journ. Asiatic Soc. Bengal, Ixiv. (2) p. 275 (1895). 



Our single specimen, a male, is only about 7"5 mm. in length, and the jjoiuts of 

 difference from the figure of Adams and AVhite are probably due to its small size. The 

 surface is rather smoother, the incision marking off the hepatic prominence posteriorly is 

 hardly perceptible, and the posterior edge of the carapace is more regularly crenated.
