MEMOIRS OF TBF QVEEBSLAFI) MVSEVM. 
Bange : — So far only known from Darnley Island, where two small speci- 
mens were collected and forwarded to the Queensland Museum by Dr. J. R. Tosh. 
Bemarls : — Very closely allied to Bleumus yatehei Jordan & Snyder. 
Both these species can be at once distinguished from B. tasmaniiis by the forward 
position of the vent, which in the latter species is nearer to the root of the 
caudal than to the tip of the mandible. The length of the type is 46 millim., 
its register number in the Queensland ^Museum being I. 13/1450. 
Family TETRAODONTID^. 
SPHEROIDES MULTISTRIATUS (Richardson). 
Ancliisomus miiltistriatus Richardson, Voy. Herald, 1854, p. 160, pi. xxix. 
Tetrodon inuUistriatus Gunther, Brit. Mns. Catal. Fish., viii, 1870, p. 285. After Richardson. 
Type locality : — Southern Polynesia. 
Body robust, the back rounded and much narrower than the belly, its 
upper contotir feebly emarginate between the occiput and the dorsal fin, its 
depth 3-4 in its length, e(iual to its width immediately behind the pectoral, and 
1-33 in the length of the head. Free caudal peduncle as long as the snout and 
anteriorly as deep as wide, becoming more compressed behind, where its depth 
is sube(iual to the interocular width. Head large, its depth aboi;t one tenth 
more than its width and 1*25 in its length, which is a. little less than the trunk 
and 2-55 in the length of the body ; occiput elevated, the osseous crest forming 
the highest point of the dorsal contour. Upper surface of snout linear and 
declivous, the mouth well below the level of the eye; anterior outline of chin 
somewhat ri'ceding, its depth 2-1 in the length of the snout; cheek very high, its 
depth, below the middle ot the eye, but little less than the length of the 
snout. Eye small, not adnate to the lower lid, encroaching far upon the cephalic 
profile, its diameter 5-8 in the length of the head, 3-2 in that of the snout, 
and 2 in the interocular width, which is concave, with a low median longitudinal 
ridge. Nostrils pierced in a i)i’ominent papilla. 
Skin of abdomen rather coarsely striated; rest of body and head more 
finely so, except the loAver half of the tail and the lips, which are smooth. Back 
with foTir regular series of rather small distant two-rooted spines, which con- 
verge ontlie occiput, on whicdi anteriorly they are more crowded than elsewhere; 
interorbital spines small and eonc(*aled; cheeks with two series of small widely 
separated spines and a small cluster in front of the gill-opening, the anterior 
border of which is protected by a row of much stronger spines; abdominal 
spines nmch more numerous and mostly concealed, arranged in about twenty 
regular series between the throat and the vent. Lateral line inconspicuous ; sides- 
with scarcely a trace of a lateral fold.
