specimens do not represent E. danrlca but that they belong in E. god- 

 dardi. 



It is probable that the references of Bleeker and Karoli to this species 

 in Thailand are incorrect and should apply to E. metdllicus. The 

 writer's own very extensive collecting in all parts of Thailand yielded 

 no specimens that could be referred to danrica, a well-known Indian 

 species. 



ESOMUS GODDARDI Fowler 



Esomus danrica Fowler, 1934a, p. 113 (Chiengmai, Metaug) ; 1935a, p. 110 (Bang- 

 kok, Sriracha). 



Esomus goddardi Fowlek, 1937, p. 170, fig. 106 (Mepoon, Pitsanulok, Tachin, 

 Bangkok, Kemarat). 



This fish is common in Central Thailand. In addition to the record 

 for Kemarat on the Mekong, there are in hand specimens from a road- 

 side pool at Kumpawapi, Udon, February 27, 1929. Identifiable as 

 this species are five specimens collected by the writer January 4, 1926, 

 from a pool at Angkor Wat, Cambodia. 



A length of 8.5 cm. is attained. In a specimen 5.4 cm. long from 

 a ditch at Nontaburi above Bangkok, the lateral line terminates slightly 

 posterior to the midbase of the anal fin. 



The characteristics of the species are an incomplete lateral line 

 which may extend only to the ventral fin but usually reaches the anal, 

 a long rostral barbel extending well behind the eye, a long maxillary 

 barbel extending to or beyond the origin of the anal fin, and a dark 

 gray line along the side from the head to the base of the caudal fin. 



Examples from Bangkok referred to E. dannca by Fowler (1935a) 

 appear to belong to this species, having the lateral line extending to 

 the ventral or anal fin. Various specimens from Northern Thailand 

 collected by Deignan have the rostral barbel not extending beyond the 

 eye but are otherwise referable to E. goddardi.

Described from Petchaburi, probably from the Petchaburi River, 

 in the Southwestern part of Central Thailand, this species has since 

 been found in various other parts of the Central region and in the 

 Peninsular and Southeastern area. It occurs throughout the Menam 

 Chao Phya and it is especially common in the Bangkok district.
