of the typical form among those sent me from the " Golden Crown." A number of 

 severed saws, however, appear to belong to this form.

I do not now think that this form is more than a variety of P. pcdinattis, if, in- 

 deed, it is not the typical adult male of that species. The main difference lies in the 

 coloration, and this is not only a character that is lost in dried specimens, but is also 

 one that may very well be sexual or even seasonal. In all the species of the genus 

 variation occurs as regards the exact proportions and outlines of the fins and saw, 

 and I do not think, after comparing dried specimens, that the structural features 

 which separate P. annandalei from the specimens of P. pectinatns in the Museum, 

 are beyond the limits of such variation, although I agreed with Mr. Chaudhuri at the 

 time he described his species that it was new. When fresh it exhibited a brilliancy 

 of coloration much superior to anything that I have seen in any other specimen of 

 the genus. The back was of a bright ashy grey, which faded into blue on the sides 

 and then changed to pale yellow. The anterior margins of the dorsal fins were bluish 

 grey, but the body of all the fins was orange-yellow suffused with red. The claspers 

 were of a bright brownish red, and there was a conspicuous orange- red line running 

 down each side of the saw and interrupted by each tooth. The following are the 

 measurements of this specimen, which was taken in July off the coast of Burma in 

 shallow water.

The rostral teeth are slender, measuring only from 7 to 8 mm. in width at the base 

 and from 21 to 26 mm. in length. There are 24 on the right and 25 on the left. 



A successful cast of this specimen was made and was coloured from a water-colour 

 sketch of the fresh specimen. Figure 4^ plate v, is a reproduction of a photograph 

 of this cast. The skeleton and part of the skin have also been preserved in the Indian 

 Museum, the number in the Museum register of fishes being F ^^^s

The rostrum in this species is longer in proportion to the body than that of P. 

 pectmattis ; the rostral teeth are stouter, and in old specimens they are often as much as
