jaw longer than upper, maxillary reaches to vertical of anterior 

 margin of orbits. 



Dorsal 17, 19. Disk elliptical, rather broader posteriorly than 

 anteriorly; length twice the breadth and 2| times in total length 

 excluding caudal ; 17 transverse laminae each with a toothed 

 posterior margin, the teeth being in 3 rows, a smooth elevation 

 dividing the disk along central line ; the most anterior laminae are 

 directed forwards, the most posterior slightly backwards, the 

 remainder nearly transverse ; external to the disk is a moderately 

 wide fleshy membrane which posteriorly extends nearly to tip of 

 pectorals and anteriorly does not reach to point of snout. The 2nd 

 dorsal is situated opposite the anal, commencing midway between 

 last lamina of disk and base of caudal and highest in front, the 

 anterior rays being about -?- length of head. Pectorals situated 

 behind posterior upper angle of operculum and opposite last 3rd 

 (14th lamina) of disk, nearly f length of head. Ventrals nearly 

 | length of head, their length about equals the distance between 

 root of pectorals and anterior margin of eye. Anal 17, similar to 

 soft dorsal. Caudal deeply emarginate, slightly more than f length 

 of head. 



Colour (of preserved specimen), uniform brown; the specimen is 

 covered with dried mucous, which gives it a bluish tinge. 



One specimen, 163 mm. in length, from Mr. Eomer Eobinson, 

 Natal. 



ECHENEIS CLYPEATA, Giinth. 



Teeth, an outer row of widely set strong teeth on anterior part of 

 lower jaw, and on vomer. Depth of body 8 times in total length 

 excluding caudal ; length of head including disk 2 times, without 

 disk 3^ times ; breadth of body between pectorals 5f times. Eyes 

 about 6 diameters from end of snout and 10 times in length of head; 

 situated about the centre of the length of head and 8 times their 

 diameter apart. Lower jaw longer than upper, maxillary reaches to 

 the vertical from the 2nd lamina. 



Dorsal 13, 17 ; disk elliptical, broadest in centre, width nearly 

 f its length, which is about 2i times in total length excluding caudal 

 and extending backwards nearly to tip of pectorals ; 13 transverse 

 laminae each with two rows of teeth on the posterior margin, a 

 smooth elevation dividing the disk along central line, anterior 

 laminae directed slightly forwards, central nearly transverse, posterior 

 slightly backwards ; a wide fleshy membranaceous margin to disk. 

 The 2nd dorsal is situated in the posterior 3rd of the body, com-
