states that in the specimens examined by him it is always the k'i't that ii 

 the larger. The Lirgest of my specimens measures 22 mm. in knigth — 

 i.e., half the length given by Thomson for his largest specimen. 



'. Arete dorsalis Stimpson. 



? Arete dorsalis Stimpson, Pruc. Acad. Nat. Sci. Philad., 12, 1860 ; Coutiere, 

 Fauna and Geog. Maldive and Laccadive Archipelagoes, vol. 2. pt. iv, 

 p. 866, 190-1. 



Three specimens from Coral Bay, Sunday Island. 



These specimens are only provisionally referred to this species ; they 

 agree with the description given by Coutiere in most respects, but differ 

 in having the inner margin of the fixed finger regularly convex and without 

 separate teeth, while the carpus of the smaller chelipeds is made up of 4 

 joints instead of the typical 3 found in this genus. The Kermadec speci- 

 mens ^vill therefore probably form a separate species, but in the meantime 

 I prefer to leave them provisionally under the above name. 



Arete dorsalis is found at Samoa, New Caledonia, Hong Kong, and at 

 the Laccadives. 



Synalpheus sp. 



From Coral Bay and Meyer Island ; several specimens. 



Owing to want of some of the necessary works of reference these speci- 

 mens have not yet been satisfactorily identified; they represent one, or 

 perhaps two, species. 



Betaeus sp. 



Four specimens from Coral Bay, Sunday Island, collected by Mr. T. 

 Iredale. 



Not yet identified. The species to which these specimens belong is 

 quite distinct from Betaeus aequimanus Dana, which occurs fairly com- 

 "nionly on the New Zealand coasts. 



Suborder Reptantia. 



Jasus hiigelli (Heller). 



Palinurus hiigelii Heller, Reise der " No vara," Crust., p. 96, pi. 8, 1868; 

 Haswell, Cat. Aust. Crust., p. 172. 1882. Palinurus tumidus Kirk, 

 Trans. N.Z. Inst., 12, p. 314, 1879. 



One small specimen from Sunday Island ; the dried abdomen of another 

 was found on the beach at Denham Island. 



The species is common on the east coast of Australia, and is occasionally 

 taken in the northern part, of Auckland. 



Thenus orientalis Rumph. 



Thenus orientalis Rumph, Mus., pt. 2. fig. D ; Haswell, Cat. Aust. Crust., 

 p. 170, 1882; Spence Bate. Rep. Voy. " Cliallenger," 24, p. 66. 

 1888 ; Borradaile, Trans. Linn. Soc, Zool., 13, p. 261, 1910. 



A specimen 40 mm. long with bilobed rostrum and a strong spine on the 

 abdomen appears to belong to this species, but the descriptions that I have 

 been able to consult are short and incomplete.
