The steamer Blake obtained two specimens of this species, 53 millimeters and 52 milli- 

 meters long, respectively, from station cccxxvii, in 34° 00' 30" N. lat., 70° 10' 30" \V. Ion. 

 at a depth of 178 fathoms; and two spccimeus from station xcvii, off Barbadoes, at a depth 

 of 200 fathoms. 



Specimens were taken by the Albatross from station 2397, in 28'= 12' N. lat., 80^ 36' 

 W. Ion. at a depth of 280 fathoms; and from station 2426, in 36° 01' 30' N. lat., 71° 47' 30"

LIOSCORPIUS, Gunther. 

 Lioseorpius, Gunther, Challenger Report, i. Part vi, p. 40, pi. x\ii, lig. C. 



Scorpwnids with head and body compressed, the former with mnciferous cavities 

 above, and with scarcely any ridges or spines. Occipnt without groove, naked. Three 

 strong sharp spines ujjon the preopercnlinn and two upon the opercular flap. The month 

 very large, the snout elongate, the curve of the mouth l)eing downward. Orbit encroaching 

 upon upper outline of head. Body co\ered with small scales, and with a wide, naked lat- 

 eral line with about 28 skinny tubes. Dorsal fliis separate; the first low, with eight or 

 nine spines, the first, second, and third evenly graduated. Pectoral fin long, lanceolate, with 

 simple rays. Teeth villiform in bands in the Jaws and on the vomer and palatine bones. 

 Branchiostegals Vii. 



The type of this genus is Lioseorpius loiu/ircps, (iiiiither, loc. cit., pi. xvii, fig. 0, which 

 closely resembles Sctardics imrmatus in torin, except tlint its head and snout are longer, 

 and the upper jaw curves downward. The genus seems well enough separated fi-om 

 iSetarches by the suuioth, grooveless occiput and the simple character of the rays of the 

 pectoral.

 orbital and preopercle, usually covered by skin; upi)er angle of preopercle usually with one 

 or more spinous processes. Teeth in villiform or cardiform bands on Jaws, and (usually) on 

 vomer and palatines; premaxillaries protractile; maxillary without supplemental boue.
