X I v.— DESCRIPTION OF A NEW SPECIES 

 OF DAN 10 FROM LOWER 

 ; BURMA. : .: 



., • By B. L. Chaudhxjri, B.A., B.Sc. (Edin.). 



Danio annandalei , sp. nov. 



Br. iii. D I. 15 ; A II. 16 ; P. 13 ; V. I. 8 ; C 28; L. Lat. 46 to 50; 

 L. Trans. 13/3. 



Height of body in the total length 3 ; length of head in the 

 total length 6 ; interorbital width in length of head 2 ; diameter 

 of eye in the length of head 4. 



The lower jaw is the longer and forms a part of the profile; 

 the cleft of the mouth is directed obliquely upwards and outwards. 



Barbels. — Two small pairs. The anterior (rostral) pair is once- 

 and-a-half as long as the posterior (maxillary) pair, which is con- 

 tained five times in the length of the head. 



Fins. — Dorsal commences six rays in advance of the anal^ 

 and there are sixteen rows of scales before its commencement. Pec- 

 torals do not reach the ventrals and there is an appendant superior 

 and inner to each pectoral fin not longer than the interorbital 

 width. The ventral fin is smaller and shorter than the pectoral 

 and has no appendant. The anal fin is situated three rows of 

 scales below the lateral line. Fins are dift'usedly spotted with black 

 spots. The caudal fin is deepl}^ forked. The lateral line is concave 

 and runs from behind the origin of the pectoral fin to the root of 

 the caudal fin. The position of the vent is immediately anterior 

 to the anal fin. 



Colour and markings. — There are numerous dark spots on the 

 opercles and suborbital region, but none on the scaleless part of the 

 head. The scales are spotted and prettily fringed with dark spots. 

 The back, which is highly curved, is steel-blue, below which the 

 upper one- third is faintly yellow, followed by the middle third, which 

 is variegated in bands and dashes to be described hereafter ; then the 

 lower third is faintly yellow (like the upper third), and is terminated 

 by the highly curved silvery belly. As the markings of the middle 

 third are conspicuously different from those found in other alHed 

 species, they are described below rather minutel}^ — 



{a) Transverse markings. — One transverse steel-blue bar in 

 the pale yellow ground just behind the opercle, 

 broad above and tapering below, followed by a 

 transverse yellow band rather narrow, then a lighter 

 steel-blue transverse band edged with light yellow.
