128 MEMOIES OF THE QUEENSLAND MUSEUM. 



Range: — 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. 



Remarks: — Very closely allied to Blennius yatebei Jordan & Snyder. 

 Both these species can be at once distinguished from B. tasmanius 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.

Type locality: — Southern Polynesia. 



Body robust, the back rounded and much narrower than the belly, its 

 upper contour feebly emarginate between the occiput and the dorsal fin, its 

 depth 3-4 in its length, equal 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 subequal to the interocular width. Head large, its depth about 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 receding, its depth 2-1 in the length of the snout ; cheek very high, its 

 depth, below the middle of 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 prominent papilla. 



Skin of abdomen rather coarsely striated; rest of body and head more 

 finely so, except the lower half of the tail and the lips, which are smooth. Back 

 with four regular series of rather small distant two-rooted spines, which con- 

 verge on the occiput, on which anteriorly they are more crowded than elsewhere ; 

 interorbital spines small and concealed; 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 much 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.
