The examples from C. Verde Islands and from the coast of West Africa are very 

 similar to those from the western Atlantic, and I have hesitated to regard them as 

 a distinct species. In 9 specimens from Brazil and the West Indies I count 58 to 65 

 scales in the lateral line, but the supplementary scales are numerous in this region, 

 making an exact count difficult. In I2 specimens from C. Verde Islands and West 

 Africa there are 54 to 60 scales in the lateral line and the supplementaries appear to 

 be usually less numerous. When specimens of equal size and of the same sex are 

 compared, the interorbital width seems to be a very little narrower in West African 

 examples, but I am unable to detect any other differences. If the form from the eastern 

 Atlantic be regarded as a distinct subspecies it will stand as Syacium micruriim 

 guineensis (Bleeker).
