FRESH-WATER FISHES OF SIAM, OR THAILAND 37 



The Thai Government courteously lent to the United States National 

 Museum over 100 original drawings of fishes from which a selection 

 has been made for illustrations for this work. These drawings were 

 made by the talented Thai artists Luang Masya Chitrakarn and Nai 

 Chote Suvatti. A number of very accurate and beautiful watercolor 

 drawings of fishes from life, by Luang Masya, could not be used in the 

 present work because of the cost of reproduction and legal interdiction. 



An invaluable aid was rendered by foreign ichthyologists in com- 

 paring Thailand fish specimens with types and other material in their 

 respective museums and in furnishing information regarding particu- 

 lar specimens in those museums. Special acknowledgment is due to 

 Dr. Baini Prashad, superintendent of the Zoological Survey of India, 

 and to Dr. Sunder Lai Hora, assistant superintendent of the suiTey 

 and the leading present authority on Indian fishes, who during many 

 years courteously made critical examination of Siamese material and 

 comparison with Indian specimens, and, on behalf of the Indian 

 Museum in Calcutta, sent valuable specimens to the United States 

 National Museum. In Holland, Dr. L. F. de Beaufort, of the Zoolog- 

 ical Museum in Amsterdam, and Dr. Frederik P. Koumans, of the 

 Royal Natural History Museum in Leiden, were ever ready to exam- 

 ine specimens sent from Siam and to compare them with Bleekerian 

 types and other material deposited in those institutions. At the Mu- 

 seum of Natural History in Paris Dr. Jacques Pellegrin provided de- 

 tailed descriptions of certain inadequately described oriental species 

 and made possible the identification of Siamese material. The au- 

 thorities of the British Museum provided facilities for the examination 

 of the extensive collection of Siamese fishes in that great institution, 

 and J. R. Norman and Dr. Ethelwynn Trewavas very kindly examined 

 certain Siamese specimens sent for determination, compared the types, 

 and made identifications. 



To Henry W. Fowler, curator of the department of ichthyology in 

 the Academy of Natural Sciences of Philadelphia, thanks are due for 

 his courtesy in examining and lending Siamese fish material forming a 

 part of the collection of R. M. de Schauensee, and for sending to the 

 United States National Museum, as donation or exchange, certain 

 valuable specimens from that collection. 



At the American Museum of Natural History in New York City, 

 John T, Nichols, curator of recent fishes, kindly made available for 

 examination certain specimens of Chinese fishes for comparison with 

 Siamese material, and offered valuable suggestions in regard thereto. 



Others who have been helpful through suggestions or through the 

 loan of specimens are Dr. Carl L. Hubbs, curator of fishes in the Museum 

 of Zoology of the University of Michigan, and Dr. George S. IMyers,
