10 ON NEW GENERA AND SPECIES OF FISHES 
EH. fulvipes, since all the others have the second pectoral 
ray divided.* . exsiliens may easily be distinguished by 
the equality in length of the two first pectoral rays and the 
anterior position of the ventral fins, which are inserted 
midway between the root of the caudal and the eye. 
Described from a fine specimen in the collection of the 
Australian Museum, Sydney; Reg. No. I. 1955. I have 
also examined a second specimen (unnumbered and without 
locality), labeled in Bleeker’s handwriting “ Hxocetus 
extliens.”’ 
Under the heading of ‘‘ Hxocetus unicolor? C. V.”t 
Kner§ records an exoccetid from Sydney; but we know 
from Bleeker’s personal examination of the three examples 
upon which Valenciennes established his species, and which 
are part of the collection in the Jardin des Plantes, that 
this is a hybrid form composed of two specimens of 
Cypsilurus and one of Exonautes. 
Bleeker’s remarks on the three specimens mentioned 
by Valenciennes are as follows, and in my opinion form 
* T am unable to speak with certainty regarding Exocetus ilna 
Clarke, as the author’s long and rambling description gives but little clue 
as to its position, and the important characters connected with the upper 
pectoral rays are entirely omitted. Judging from the similarity of the dor- 
sal and anal fins we believe it to be Hxonautes. 
+ I take this opportunity of publicly thanking the Trustees and Curator 
of the Australian Museum for their kindness in lending me their valuable 
collection of fiying-fishes.

+ The following is a translation of Valenciennes’ description :— 
L’Exocet aux pectorales unicoldres. 
(EXOC@TUS UNICOLOR nob. 
Another species from the Seas of India— 
has the occiput flattened and the snout a little compressed, like that of the 
Mediterranean (Hxocetus volitans), but the eye is much larger and the head 
longer. The length of the head is somewhat less than } of the total 
length (c.c.). The orbital diameter is 4 of the length of the head. The 
dorsal fin is low and nearly equal (in height). 
DSi eA Lae 
The color of the back, like that of the preceding species (Hxocetus 
speculiger) is uniform plumbeous ; the pectorals are violaceous gray, without 
either the white spot or border of the preceding species. The ventrals are 
white, with a small gray longitudinal spot near the axil. 
The specimens are a foot long; they have been brought from Vanikoro 
and Java by MM. Quoy and Gaimard; a third has come to us from the 
Seas of India by the courtesy of M. Dussumier.
