The loreai shield described by Krett't, and later stated by Giinther to 

 be accidental, is an abnormal, divided nasal, tlie division having taken 

 place well behind the nostiil, and its suture conne(!ting with that of the 

 internasals and prefrontals. This character is present on both sides of the 

 head. In all other lespects Krelft's type agrees with the descripti<ni of 

 D. macnhda, as given by Mi'. Boulenger.

As the original tigui'es of this specimen do not show the head shields 

 very clearly, and as they are not quite correctly delineated, 1 have re- 

 drawn them as shown here (Figures 1-3).
