absence of any decided difference between the specimen obtained in Cuba by 
Gundlach and those which he has himself collected at Amboina compels him to 
reverse this opinion and to recognise the occurrence of the species in the tropical 
Atlantic. He says that the specimens from the Atlantic are smaller on the average 
than those from the Indian Ocean, that the rostral spine is a little shorter. He 
points out also a slight variation among the Cuban specimens in the terminal spines
