maxilla sequalibus trigonis, obliquis, latis, totis denticulatis, basi 

 externa processu serrato. Pinna dorsali prima pinnis pcctoralibus 

 multo magis quam ventralibus approximata, corpore paulo humiliore, 

 paulo altiore quam longa, apice acutiuscule rotundata, emarginata, 

 postice acutissima. Dorsali secunda anali opposita, quadruple cir- 

 citer ejus longitudinis a pinna dorsali prima remota, dorsali prima 

 plus duplo humiliore et breviore. Pcctoralibus capita multo breAdo- 

 ribus, emarginatis, apice acute rotundatis, latitudine basi 3 fere 

 in earum longitudine. Anali ventralibus plus quam caudali ap- 

 proximata, dorsali secunda altiore sed non longiore, valde emar- 

 ginata, apice acuta, postice acutissima. Caudali 3| circiter in 

 longitudine corporis. Colore corpore superne griseo-caeruleo fasciis

Snout rather pointed, of moderate length, the distance between 

 its end and the mouth being more than the length of the mouth, 

 and about two-thirds of its width. Nostrils much nearer to the 

 mouth than to the end of the snout, but nearer to the end of the 

 snout than to the angle of the mouth. Teeth in the upper jaw 

 oblique, serrated on both margins, and with a deep notch on the 

 outer margin ; teeth of the lower jaw narrow, erect, lanceolate, 

 serrated, on a broad, two-rooted base. Gill-openings at least twice 

 as wide as the eye. Pectoral fins narrow, pointed, falciform, the 

 length of their inner margin being one-fourth of that of the outer. 

 Dorsal fin rather nearer to the pectorals than to the ventrals, its 

 distance from the pectorals being but little less than the length of 

 its base. The second dorsal very small, shorter and lower than the 

 anal. Origin of the anal opposite to that of the second dorsal, and 

 midway between the ventral and caudal. The length of the caudal 

 is one-fourth of the total. Coloration uniform.

 Cuba, 1868, p. 448, = Squalus acronotus, Poey, 1. c. p. 335, from 

 Cuba, appears to be ver}"^ closely allied to O. brachyurus ; but it is 

 probable that specific differences will be found when examples from 

 both localities can be compared.
