its leiigtli instead of oiie-fourtli ; its width is one-fonrtb instead of three- 

 twentieths; the length of the liead nine-twentieths instead of three- 

 eightlis. The width of the interoibital area is half the length of the np- 

 per jaw instead of one-fourth, and is nearly equal to instead of one half of 

 the diameter of the orbit. The vertical fins are inserted fiirther back, 

 the paired tins farther forward, and the fins are, without exception, 

 longer. The tail appears to be truncate instead of emargiuate, as in >S. 

 mariuKs. The preopercular spines are very ])ronHnen(. The spinous 



dorsal contains ten spines.

A fishing smack from Noank, Conn., was engaged by Professor 

 Baird to set a trawl on the edge of the oceanic; slope, in the hope of ob- 

 taining more specimens of Lopholatilus. Their only capture was a 

 sword-fish thirteen feet long and weighing over 000 pounds. This was 

 brought up from the bottom on the trawl-line. There is room for much 

 question whether it was taken at the bottom or fastened itself to the
