Closely resembles A. phosphoropsj from which it differs In 

 the following particulars : — 



1. Tlie premaxillary teeth are fewer in number and are 

 relatively larger; they are arranged in two sets, an anterior 

 closely set group of eight or nine, and a posterior group of 

 three with wide intervals between. 



2. The interorbital space is wider than half the diameter of 

 the eye. 



3. The head is covered with a firm smooth skin just as in 

 A. phosijhorops, but in the new species the colour of this 

 skin is a dark slatj^ blue. The colour of the rest of the body 

 is brownish black. The bases of the fins have a blue tinge. 

 The blue colour is partially preserved in spirit. 



4. The total height is only \ of the total length excluding 

 the caudal fin, but as this specimen is smaller and younger 

 than the type of A. pihosphorops , this character does not, 

 perhaps, constitute a specific diflference. 



One damaged specimen, 18 cm. long, from 1005 fathoms 

 in the Gulf of Oman. 



Tlie wide distribution of the three specimens and the close 

 similarity in the depths from which they were obtained are 

 points worth noting.

Resembles A^. pluriseriaUs (Gorman), and differs from 

 N. erimelas (Alcock) in the following particulars : — 



1. There are seven branchiostegal rays. 



2. The first ray of the anal fin is vertically below the 

 eighth ray of the dorsal. 



3. There is one enlarged tooth on either side of the vomer. 

 In all its proportions this species resembles iV. pluriseriiUi's 



very closely. 



It differs from N. plui'i'serialis in the following respects: — 

 1. The teeth in the maxillje are in two series, an outer 



series of small teeth and an inner series of lariicr ones.
