Holt and Calderwood — Report on the Rarer Fishes. 



375 



Size. — The maximum size recorded is 142 cm. (4 feet 8 inches), Bocage and 

 Capello. 



Vernacular Names. — At Setubal, Arreghonda (B. & C.) ; An-egonhada (Vaillant). 



Description of Specimen. — Only a single example was taken during the 

 Survey; it is an adult male. A sketch of it is given in fig. 1, PI. v.

Proportions. — The eye is equal in length to the snout ; its length is greater 

 than the width of the interorbital space, and less than the distance between the 

 spiracles. The length from the tip of the snout to tlie last gill slit is contained 

 about 4i times in the total length (without the caudal), and is somewhat greater 

 than the greatest height of the body. The extreme length of first dorsal fin is equal 

 to 2| times the height ; in the second dorsal fin the length is If times the height. 

 The base of the second dorsal is two-thirds of the base of the first dorsal, which 

 is one-third of the interspace between the two fins (spines excluded in these 

 measurements). The extremity of the outer lobes of the pelvics are about opposite 

 the base of the second dorsal spine, the extremities of the claspers opposite the 

 middle of the base of the second dorsal fin. 



Shape. — When newly caught the specimen presented a plump, well-rounded 

 contour, with no marked trihedral aspect in section, such as characterises many 

 ground sharks, though the ventral surface was slightly flattened. It has been
