are two species in waters so close together as those of Sumatra and the 
Cape of Good Hope. 
5. TETRAPTURUS GEO.2GIL. 
Tetrapturus Georgii, Lowe, Proc. Zool. Soc. viii, 1840, p. 36: Trans. Zool. Soc. 
iii, 1849, p. 3 (reprint of first).—GUNTHER, op. cit. p. 512, foot-note.—LUT- 
KEN, ll. c. 
This species, known at Madeira as “ Peito”, was described by Lowe 
thus briefly: “Iam enabled to state that it forms a new and very dis- 
tinct species of Tetrapturus, Raf., differing from T. belone, Raf., as de- 
scribed by MM. Cuvier and Valenciennes, especially in having the 
pectoral fins proportionately twice as long, and the body clothed with 
large scales of a peculiar shape and character.” 
Liitken believes it to be identical with the two species of the Indian 
Ocean just discussed, as well as with the two Cuban species. It should 
surely be carefully compared with the latter. 
6. TETRAPTURUS ALBIDUS, Poey. 
Tetrapturus albidus, Pory, Mem. Hist. Nat. Cuba, ii, 1858, p. 237, pl. xv, fig. 1; 
pl. xvi, figs. 2-13; pl. xvii, figs. 1, 5, 6-9, 10-11, 26: Ib. p. 258: Rep. Fis. 
Nat. Cuba, ii, 1868, p. 380.—GILL, Cat. Fish E. Coast N. A. 1873, p. 24.— 
LUTKEN, Jl. ¢. 
7. TETRAPURUS AMPLUS, Poey. 
Tetrapturus amplus, PoEY, op. cit. p. 243, pl. xv, fig. 2; pl. xvi, figs. 12-25: Rep. 
Fis, Nat. Cuba, ii, 1868, p. 380.—LUTKEN, Il. ¢. 
These two species described by Poey from Cuba, one of which, 7’. al- 
bidus, is not uncommon on the Atlantic Coast of the United States, 
have already been partially discussed, and a translation of Poey’s 
description is given in the appendix. Liitken is disposed to consider 
them both identical with the 7. indicus type, and it seems to me that 
there is as much reason for doing this as for throwing together the Sail- 
fishes of the Atlantic and Indian Ocean, as has been persistently done 
by all writers on ichthyology. 
8. TETRAPTURUS BREVIROSTRIS (Giinther & Playfair). 
“‘ Histiophorus brevirostris, GUNTHER & PLAYFAIR, Fishes of Zanzibar, 1866, 
pp. 53, 145, figure.”—Day, Fishes of India, 1876, p. 199, pl. xvii, fig. 3. 
Tetrapturus brevirostris, LUTKEN, 1]. c. 
Histiophorus, KNOX, Trans. New Zealand Institute, ii, 1870, pp. 13-16, fig. 1. 
This species, the habitat of which is given by Day as “? East coast of 
Africa, seas of India, perhaps New Zealand”, is referred by Liitken to 
the same species with 7. indicus and J. Herschelii. Day considers it 
closely allied to Tetrapturus Lessone, Canestrini. 
9. TETRAPTURUS LESSON&, Canestrini. 
Tetrapterus Lessone, CANESTRINI, Arch. Zool. 1861, i, p. 259, pl. vii —LUTKEN, 
I. e.—Day, lhe. 
This species, described by Canestrini from the Mediterranean, is re- 
ferred by Liitken to the general cosmopolitan type, of which 7. indicus 
and T. Herschelii are the representations.
