Diodon holacanthus. Jordan & Evermann, 1. c., 1746,1898. 
Genus 127. CHILOMYCTERUS Bibron. Burr-fishes. 
Body broad, depressed, moderately inflatable. Dermal spines short, stout, immovable, triangular, 
each with 3 roots; nasal tube simple, with 2 lateral openings; tube sometimes rounded, sometimes 
flattened, and with partition feeble and easily torn, so that tentacle appears divided; caudal peduncle 
short; fins small, formed as in Diodon; jaws without median suture. Species numerous, of smaller 
size than those of Diodon, spines broader and lower, their bases forming a coat of mail. 
Cyclichthys: 
a. Nasal tentacle subeyliudrieal, not divided. 
b. Fins unspotted; supraorbital spines 2, with generally a tentacle between them; a spine in middle of forehead. 
c. Superciliary edge raised. 
<?. Upper parts greenish-black, with a series of undulating blackish stripes running from nape backward; a similar 
series between eyes and across face; an ocellated black spot above pectoral; a larger one behind pectoral; an 
ocellated spot on each side of dorsal, and an elongated spot behind each of ventral antennse scha-pfi 
dd. Upper parts plain, without series of lines; spots as in C. schaipfi spinosus 
ddd. Upper parts covered with black, hexagonal reticulations antillarum 
cc. Superciliary edge not raised; upper parts with numerous black dots, some with bluish centers; a black spot in 
middle of nape; a large kidney-shaped spot above pectoral, and a subtriangular blotch before and along base 
of dorsal fin; a series of antenn® along lower part of side antennatus, 230 
Chilomycterus: 
aa. Nasal tentacle flattened, divided; fins spotted with black; supraorbital spines 3, feeble, none on forehead. 
e. Supraocular cirrus well developed; upper parts densely covered with small, round, blackish spots; a large black 
blotch before and around dorsal, another on each side above gill-opening and pectoral; spines short, compressed, 
anterior root flat, longer than the others atinga 
230. Chilomycterus antennatus (Cuv ; er). Spiny Puffer. 
(Plate 42.) 
Spines strong, but short; 2 above orbit, 1 more or less prominent in the middle of forehead. 
Superciliary edge not raised; generally a tentacle between superciliary spines. Tentacles along lower 
part of side, 1 on each side and in advance of anal tin being especially developed. Tail spineless, but 
roots of one pair of spines reaching across behind dorsal fin. 
A black spot in middle of nape; a large kidney-shaped spot above pectoral, and a subtriangular 
blotch before and along base of dorsal fin; generally a small black spot below eye; some or all of these 
spots edged with lighter; upper and lateral parts with numerous black dots, some with a bluish pupil; 
abdomen brown; fins unspotted. 
In an example 3 inches long, obtained at Mayaguez, and from which plate 42 in this volume was 
made, the general color is a light-brown, somewhat darker on back and under parts; a large grass- 
green blotch on occiput, a similar oblong one above base of pectoral, and another on back across base 
of dorsal fin; back, head, and side with numerous small, roundish black specks; iris yellow, pupil 
pale-blue; fins all pale-blue or greenish-blue. 
West Indies and ranging southward; recorded from St.. Croix, Jamaica, Porto Rico, and Cape of 
Good Hope. Length S inches. One specimen seined at Mayaguez and one taken at San Geronimo.
