Aneitum, Australia. 
Head, 2| in length; depth of caudal peduncle, 3 in head; eye, 6; 
snout, 2i; interorbital space, 3; dorsal rays, 10; anal rays, 10. 
Body robust, the belly enormously distensible, caudal peduncle 
compressed; the length 2i in head. Length of head less than distance 
between gill opening and insertion of dorsal. Interorbital space flat or 
somewhat concave, the distance between eyes 3i times their diameter. 
Cutting edges of teeth concave; suture without a deep depression, on 
vertical ridges along its side. Gill opening not quite so wide as base 
of pectoral. Nostrils with bifid tentacles, without apparent openings. 
Lips, upper part of snout, bases of fins, and caudal peduncle naked; 
other parts covered with prickles or short, slender spines; those of the 
upper parts very short and pointed; of the lower parts longer, pointed, 
and with a minute, fiesh}^ bulb near the tip. Lines of mucous pores 
very indistinct; a line (encircling the eye) passing in a broad curve 
above pectoral, then bending downward and extending to base of 
caudal fin. 
Fins small, their edges rounded; dorsal and anal, 3^ in head; ?audal. 
If; pectoral, 3. 
Color blackish gray, the upper parts with oblong or rounded pale 
spots alK)ut as large as pupil; interspaces wider than spots; a large 
black blotch surrounded by a white ring around base of pectoral and 
gill opening; chin dusky; belh" whitish, with parallel stripes of black, 
which fade and grow narrower on the median part; caudal Avith small 
white spots; other fins pale or with a little dusk3\ 
Smaller specimens have the pale spots above much more obscure, 
while the black stripes on the belly are very distinct. The upper 
stripes arc most distinct and are deeper in color at intervals, leaving a 
trace of about -t dark cross bars on the side. 
In adult specimens, apparently of the same species, collected in 
Honolulu by Dr. O. P. Jenkins, the stripes on the belly are obsolete. 
In the young from the same locality they are very distinct. 
East Indies, north to the Riukiu Islands. Here described from a 
specimen, 5^ inches long, from Okinawa (Coll. Y. Koneyama), and from 
two others, each of which is about 4 inches long, from Ishigaki Islands 
(Yaeyama; Coll. Capt. Alan Owston). The larger specimen is evidently 
identical with Bleeker's imjjlutm and Richardson's laterna. The 
synonymy of Riippell we have taken from Dr. Giinther. The unidenti- 
fied description of Tetrodon hispidus seems to belong to this species. 
The type came from China and was marked by vague, dark cross 
bands, but no pale spots are figured.
