which may be visible from below between the mandibular 

 branches. 8 9 along each side of isthmus. A median series 

 beginning with 3 smaller ones on isthmus followed by 14 17 

 to anus. A small one between urogenital papilla and 4 5 

 behind anal. On each side of anus a row of 4 5 small ones.

 caudal. An inferior lateral series of 9 10 organs running from 

 above-named vertical to ventrals. A superior lateral series of 

 22 25 organs extending from dorsal base of pectorals to some- 

 what behind the end of the anal. 3 large ones before base of 

 pectorals, 3 4 smaller behind it, 2 3 small ones before base 

 of ventrals. Besides there may be some scattered small ones.

6. Scopelosaurus Bleeker. 



(BLEEKER, Act. Soc. Sc. Jndo-Neerl. VIII. 1860, Elfde Bijdr. Amboina p. 12). 



Cylindrical, elongate. Eye large. Snout long and pointed. 

 Lower jaw prominent. Gape of mouth wide, superiorly bor- 

 dered by the intermaxilla, the long maxilla situated above it. 

 Dorsal somewhat behind the middle and behind ventrals, far 

 distant from anal. Anal in the beginning of the posterior J /4 

 of the length, immediately behind anus. Adipose fin above 

 its hinder end. Pectorals in the middle of the height. Caudal 

 forked. Immovable, small teeth in one series on intermaxillaries, 

 palatines and vomer, in several series in the mandible. None 

 on tongue. Mucous membrane of cavity of mouth blackish. 

 Scales cycloid, wanting on head. Lateral line straight, composed 

 of tubules. Three ventral series of luminous organs between 

 isthmus and anal ] ). Pseudobranchiae present. Gillrakers rather 

 long and slender. Four gills. 9 branchiostegal rays. 



i) We could not make out on the type specimen, which is in a bad state 

 of preservation, if the M guttulae numerosae argenteae nitentes in series 3 longi- 

 tudinales dispositae", as mentioned by Bleeker, really are luminous organs.
