3lacrnnis heris, -whicli attains a length of about 

 half a metre, \vith eyes relatively ecjual in size to those 

 of .1/. Fabricii (35 ?„ of the length of the head) is 

 e\idently a much more pi'onounced dcc])-sea fish than 

 M. rupestris: and its more scattered, but sti'onger 

 (canine-like) jaw-teeth and relatively longer jaws are 

 signs of its more predatory habits. 



The body is remarkabh- elongated, this being due, 

 according to Gintiii;!;, to the fact that the tail "tapers 

 to a very long and narrow band." IJut the fort'|)ai't 



e.Kternally cori'esjjonds fairly closelv to that of the two 

 preceding species, the depth at the beginning of the 

 tirst dorsal tin being about ''/k, (89'7 %) of the length 

 of the head, and at the begiiming of the second dorsal 

 fin aljout "3 (64'7 %) of the same. The breadth of 

 the head straight across the cheeks at the centre of 

 the eyes is less than ",,- (38"2 %) of its length. 



The smooth spinous ra'S' in the first doi'sal tin and 

 the small scales render tliis species easily recognisable 

 among our Macruri. We must remark, howevei', some 

 (5) raised, but only sligiitly marked .stria; (osseous 

 ridges under the skin) on the operculum and suboj)er- 

 culum, radiating backwards and downw;irds from the 

 articulation of the former. 



The coloration, according to Glnthki!, is Ijrownish 

 on the liead, especially on the gill-cover, with a lustre 

 of sil\er and gold; the a.xil of the ])ectorals, the ventral 

 tins ;uid the bell\- between them, and the vent are black; 

 the dorsal and pectoi'al tins are blackish: the anal fin
