PHILIPPINE MACROUROID FISHES GILBERT AND HUBBS. 559 



66. LIONURUS VITTATUS (Weber). 



Macrurus rittatus Webek, Fische der Si&Oflra-Expedition, p. 157, pi. 1, fig. 5. 



This species, the most strikingly marked of any in the genus, was 

 not obtained by the Albatross. 



67. LIONURUS RICHARDI (Weber). 



Macrurus richardi Webek, Fische der Sibofeo-Expedition, p. 154, pi. 1, figs. 

 3 and 3a. 



This species is a close ally of L. pumiliceps and of L. decimalis, dif- 

 fering from them in the small number (8) of rays in the ventral fins. 

 No specimens Mere dredged by the Albatross. 



68. LIONURUS PUMILICEPS (Alcock). 



Macrurus pumiliceps Alcock, Journ. Asiat. Soc. Bengal, vol. 63, pt. 2, 

 1S94, pp. 125, 127; Illustrations of the Zoology of the Investigator, Fishes, 

 pt. 3, pi. 16, fig. 3; Descrip. Cat. Ind. Deep-sea Fishes Indian Museum, 

 1899, p. 113. 



This species is one of that group of Lionurus in which the whole 

 ventral region of the head and trunk has migrated forward from its 

 normal position, the snout is blunt in profile, and projects but little 

 beyond the mouth; the gill-membranes are united below the orbit; 

 the ventral fins are inserted below the middle of opercle; the anus 

 lies before the vertical from the origin of the first dorsal, and is 

 followed by the anal fin after an interval unusually short for a 

 species of the Lionurus type of genera. 



The reference of our material to the Indian L. pumiliceps is made 

 without comparison of specimens. No differences of importance are 

 apparent between our material and Alcock's descriptions, which, 

 however, are not sufficiently complete to render the identification en- 

 tirely certain. 



We present a short description of our specimens, which were ob- 

 tained at the following stations :
