2G0 On Fishes from Yunnan. 



between it and the still earlier Aphareus iaermis of Paulson 

 tend to lose tlieir importance. One specimen among Borra- 

 daile's material has the rostral crest shaped almost exactly 

 as in Paulson's figure, owing, apparently, to the breaking of 

 the anterior tooth ; the greater stoutness of the third cheliped 

 as figured by Paulson is not likely to be a valid specific 

 character in view of the great difference between the sexes 

 in this respect ; and the number of articulations in the ))en- 

 ultimate segment of the third raaxilli})cd is sometimes diffi- 

 cult to determine unless the limb be removed from the body. 

 The decision on this point, however, may be left to Dr. Balss, 

 who, I understand, has under exaraiuatiou specimens be- 

 longing to this genus from the Red Sea. 



There remains for consideration the systematic place to be 

 assigned to the genus, and on this point I find myself 

 unable to agree with Borradaile's suggestion that its affini- 

 ties are with the Sicyoninse. The characters enumerated in 

 my former paper appear to show conclusively that it belongs 

 to the Sergestidse, and in addition it may be pointed out 

 that the branched form of the adult male petasma is very 

 suggestive of that found in Scr//estes [cf. Kemp, Fisheries, 

 Ireland, Sci. Invest. 1908, i. (li/lO) pi. ii'i. figs. U & 1 J] and 

 quite unlike that oi Sicyonia. The modificatuju of the inner 

 flagellum of the antenuule in the adult male, as described 

 above, is probably to be compared with the prehensile 

 apparatus of Seryestes, although the flagellam is uot bifur- 

 cated as in that genus.

During tho last ten years Mr. John Graham has from time 

 to time sent several small collections of fishes from Yunnan 

 to the British Museum; one just received is likely to be the 

 last, as Mr. Graham is leaving yunuau ; it includes examploi 

 of a new Bariliw*.
