majority were found when shore-collecting, but a few, all very small, were taken at 
depths of 20, 30 and even 41 fathoms. 
Gonodactylus chiragra has been recorded from a vast number of localities in the 
Indo-pacific region. It extends from the Gulf of Suez (Miers, Kossmann) and the Red 
Sea (Miers, Nobili) along the African Coast southwards to Natal Point, where, according 
to Krauss, it is rather rare. Eastwards of this it seems to occur in every favourable 
situation, and on the Australian coast reaches south to the Swan River in the west and 
to Port Molle in the east (Miers). It appears to be absent from the S. coast of Australia 
and from New Zealand. In Oceania it is abundant and has been found as far east 
as Tahiti (Heller). Northwards it extends as far as Japan (Fukuda) ; but it has not, I 
believe, been taken at the Hawaiian Is. 
Miers’ record from Panama, the only one from the Pacific coast of America, re- 
quires confirmation and Nobili (1897, p. 6) and Moreira (1901, p. 1, sub G. falcatus) 
appear to have been unaware of Hansen’s separation of the Atlantic form under the

name of G. oerstedi when they recorded specimens from Darien and the Brazilian coast. 
From Hansen’s notes (1895, p. 65, footnote) and from the further study of numerous 
specimens by Bigelow (1902, p. 152), it seems certain that every Atlantic specimen 
exhibits the characters of G. oerstedi and all references of G. chivagra from these 
localities may be placed with confidence in the synonymy of that species.
