Remarks. — This new species, Danio {Allodanio) ponticulits, type of 

 the new subgenus Allodanio, bridges the gap between Danio and 

 Brachydanio, having a complete lateral line and seven branched dorsal 

 rays. 



{Ponticulus, a little bridge.) 



DANIO (BRACHYDANIO) SHANENSIS Hora 



Danio (Brachydanio) shanensis Hora, 1928, p. 38 (Namkhan, Kutaki, Laslilo, 



Hsipaw, Northern Shan States). 

 Danio shanensi!^ Fowler, 1934a, p. 113, fig. 65 (Chiengmai, Metang). 



This species was described in 1928 from the Northern Shan States 

 of Burma where it was found to be common in ricefields, in small 

 ponds, and in pools in the bed of hill streams. It was subsequent!}' 

 reported from the Southern Shan States, and in the same year Fowler 

 noted over 130 specimens from Chiengmai and the Metang north of 

 Chiengmai. The lateral line is variable. In the material from the 

 Shan States the lateral line is normally deficient posterior to the base 

 of the anal fin, although in one specimen Hora found the lateral line 

 practically complete. The figure jDublished by Fowler shows the 

 lateral line uninterrupted and extending to the base of the caudal 

 fin. The barbels are given as either entirely absent or a short, stumpy 

 maxillary pair. 



The maximum length of Thai examples is 7 cm. 



DANIO (BRACHYDANIO) ALBOLINEATUS (BIyth) 



Nuria albolineata Blyth, 1860b, p. 163 (Tenasserim). 



Danio aliolineata Masta and Indrambarya. 1932, p. 280 (Koh Samui). 



Previously known from Sumatra and Burma, this species has been 

 found to occur in certain mountain brooks in Peninsular and South- 

 eastern Thailand. It was first collected by Luang Masya Chitrakarn 

 in 1927 in a pool below a waterfall on Kao Sabap, four specimens be- 

 ing taken. In 1931 two specimens were obtained by Masya and 

 Indrambarya below the Na Muang waterfall on Koh Samui. From 

 a brook on Koh Chong five specimens were obtained in 1933, the small- 

 est example, 2.1 cm. long, having the characteristic scarlet longitudinal 

 band extending from the base of the caudal fin to the head ; this band 

 usually extends only to a point under or slightly in advance of the 

 origin of the dorsal fin. 



In Burma a length of 5 cm. is reported by Day. The largest Thai- 

 land examples have been 4.2 cm. long.

This species, which is very strikingly colored, is known only from 

 the type, 4.2 cm. long, and three other specimens, 3.2, 3.5, and 3.6 cm.
