a. Gill rakers very short ; dorsal fin on hinder half of body. 



b. Dorsal fin well forward, its last ray inserted nearly over tire iirst of anal; luminous sp.,ts over and 

 behind anal forming a nearlj continuous series. 

 . . Luminous spots appearing as impressions on the skin, not placed on black globular bodies; anal 



rays 25 to 30; double row of spots behind pectorals ceasing at \ entrals Maurojln > s. 



co. Luminous spots occurring as "convex pearls, cadi sitting on a black globular body;" anal rays 



about 14 ; double row of spots behind pectorals reaching anal Vinciguerria, now genus. 



66. Dorsal tin farther back, nearly opposite anal, its iirst raj aearlj over the front of anal; luminous 

 spots over and behind anal gathered in 5 clusters of 2 to I each, the spots on a black back- 

 ground; star-shaped pigment spots along lateral line; anal rays about 24. 



V \i EN( MNNia 1 i s. new genus. 



VINCIGUERRIA, Jordan & Evermann. 



This genus is close to Maurolicus, from which it differs, according to Liitken, chiefly 

 in the character of its luminous spots which are pearl-like and placed on black globular 

 bodies. Anal short, of 14 rays. (Named for Dr. Decio Vinciguerra, director of the Acquario 

 Romano, and one of the most active and scholarly of the naturalists of Italy.) 



VINCIGUERR] \ ATTENUATE (Cocco) Jordan & Evermann. 



Maurolicus attenuatus, Cocco, Lett. su. Salmon.. :;:;. 1838, coast of Italy; Gunther, Cat., v, 390, 1864; 

 LOtkbn, Spolia Atlantica, 271, 1892. 

 . /«» i, mini, Cuvier it Valenciennes, Hist. Nat. Poiss., \xn, 4-10, 1849; after Cocco. 



Head 3f; depth 6. D. 12; A. 14. Last ray of dorsal just behind vertical from origin 

 of anal. Luminous spots slightly prominent, "appearing as convex pearls, each sitting on 

 a black globular body;" 12 to 14 pairs of spots between front of anal and base of caudal; 

 Upper row from gill opening to ventrals with 12, 11 between ventrals and anal; from tip of 

 isthmus to anal, 7+10 + 10=3.'! spots. Length 2 inches. Open Atlantic, west to the 

 Bahamas; in deep water. (Liitken, etc.) 



VALKXCIKXXELLUS, Jordan & Evermauu. 



This genus is close to Maurolicus but with the dorsal fin farther back, opposite anal, its 

 Iirst tay nearly over front of anal. Photophores above anal gathered in about live clusters, 

 each on a Mack background; anal fin long. Deep sea. (Named for Aehille Valenciennes, 

 the associate of Cuvier, author of the greater part of the " Histoire Naturelle des Poissons,'" 

 a noble work which is the foundation of modern ichthyology.) 



VALENCIENNELLUS TRIPUNCTULATUS (Esmark) Jordan & Evermann. 



Maurolicus tripunctulatus, Esmark, Christiania Vid. Selsk., Forh., 488, 1870, Madagascar; LOtkkn, Spolia 

 At lantira, Scopelini, 19, 1892. 



Bead 3f; depth 3|. D. 9 or 10; A. about 24. Luminous spots arranged in and placed 

 on black bodies, 16 pairs in the lower row from pectorals to ventrals; 5 between ventrals 

 and anal; 5 black areas between vent and caudal about equidistant, and each one with 2 or 

 4 small luminous spots set close together (the first 3 with 3 each, the fourth with 2, and the 

 last with 4); 1 spot on preopercle, 4 near shoulder girdle; 5 in an upper row behind pecto- 

 ral; head and region along lateral line with a row of about 16 black pigment spots, some of 

 them star-shaped, with many radiations, these largest posteriorly; large and small ones 

 interspersed. First ray of dorsal slightly before first of anal. Two specimens known, one 

 front Madagascar and one from Denmark Straits, between Greenland and Iceland. 



For Opisthoproctus soleatus see figures and description in Yaillant. We have seen the 

 specimen, but it is incomprehensible to us.

ft Schneideri (= G. si, Mini) was said by Kisso to have been taken in moyennesprofondeurs 

 off Nice, but its Mediterranean habitat is probably in not less than 3(10 fathoms. The type 

 of the species, originally described by Mark Catesby, the Virginia naturalist, under the 

 name of Vvpera marina, was obtained at Gibraltar.
