306 JOEDAN & SNYDER I NINE NEW SPECIES OF 



This species is much less common than the ordinary spear- 

 fish or Kajiki. It is known to the fishermen as Mazara or as 

 Kurokajiki (Black Spear-fish.). 



Our description is taken from the single specimen seen, 10 

 ft. long without spear, taken off Misaki, in Sagami. 



It is possible that either of these species may be identical 

 with others described from other regions, but the evidence is 

 against this supposition. T. indiens from Sumatra has never been 

 intelligibly described. T. herscheli from South Africa is regarded 

 by LÜTKEN as identical with T. brevirostris from India, a species 

 which has longer ventrals. The Atlantic species, called T. 

 imperato7', or 1\ helone, is close to T. miisukurii but differs in 

 several regards. The rare T. amplus of Cuba is quite unlike 

 either. 



The two species of Telrapiurus found in Japan may be thus 

 distinguished : 



a. Pectoral fin moderate, 1 -/g in caudal lobe, 1 Ys ii^ head 

 from tip of lower jaw ; dorsal lobe about equal to pectoral and 

 about as high as body mitsuhurii. 



aa. Pectoral very long, scarcely shorter than caudal lobe and 

 very little shorter than head, from tip of lower jaw ; back 

 elevated at front of dorsal ; dorsal lobe shorter than pectoral and 

 notably less than depth of body mazara. 



5. Bentenia sesticola Joedan and Snyder, new genus und 

 new species, (Flcraclidœ) ; (PI. XVL, Fig. 6). 



Head 4 in length ; depth 3 "/a ; eye 3 Vs ii^ bead ; snout 

 4; maxillary 2 "/-j', scales 49 ; D. about 55; A. about 40. 



Body elliptical ; closely compressed. Head with the profile 

 before eye vertical. Mouth very oblique ; the lower jaw projecting.
