REMARKS ON THE GENUS SULA. 



But a young female probably about a year old tbat we 

 caught on boardship, between Malacca and Penang, Lat. 2° 

 25' N., Long. 101° 40' E. on the 8th of August, and of which 

 the dimensions and colours were most carefully recorded at 

 the time, and which I have inserted in the tables below, did 

 not agree iu these latter points. 



Here also, as it seems to me, a much smaller species still 

 to be noticed, has been confounded with the present species, 

 and it is impossible for me to make out in all cases where 

 colours of soft parts are referred to, Avhether these were taken 

 from the specimens of the true axiatralis (sula, Lin.), or from 

 the smaller.
