Halimus borradailei, nom. nov. 
Hyastenus elegans var. tenuicornis Borradaile, Proc. Zool. Soc. London, 1900, 574, pl. — 
40, fig. 2. Not Hyastenus (Chorilia) tenuicornis Pocock, Ann. Mag. Nat. Hist., 1890, 
(6) 5, 76. 
The form described by Borradaile as a variety of JZ. elegans Miers," it 
seems to me should be regarded as a distinct species, because of the different 
build of the postocular lobes, the great width between the horns at their 
base, as well as the different ornamentation of the dorsum. 
On the reef at Funafuti, Dec. 24, 1899, was taken an immature ? about 
} the size of Borradaile’s examples from Rotuma. Of the six gastric tuber- 
cles in his figure, only the outer pair are evident in our individual. In other 
respects it agrees well enough with the figure, allowing for the difference in 
size.
