the dimensions and i^eneral aspect corresponded well to the 

 drawing of the tarsus and foot of one of our Lord Howe Island 

 birds, and not to that of frecjetta lciico(/astcr, both of which 

 were enclosed in our letter to him. ^Ir. I'erlioz api)ended a 

 colour description, the translation of which is as follows: — 



"The ])lumage is a sooty brown, much darker on the remiges 

 and retrices, more pale on the wing coverts ; these are the same 

 as the feathers of the back, possessing a whitish border; with- 

 out doubt a sign of its immaturity. The lower breast and 

 the entire abdomen are white, as well as the rumj) and u])per 

 tail coverts, the under tail coverts are white at the liase and 

 brown at the tip. Total length (from base of beak to end of 

 tail), 170 mm.; culmen, 19 mm.; tarsus, 34 mm.; middle toe and 

 claw, 21 mm.; wing, 170 mm.; tail, 79 mm." 



We compared these measurements with his enclosed drawings 

 which are natural size, and we find that the culmen must have 

 been measured from the angle of the mouth ; this would give 

 the 19 mm., as noted by Mr. Berlioz (see text figure), while the 

 wing was most probably measured from the junction with the 

 body, and not from the bend, by allowing for this difference, 

 the measurement would then be from 165 — 170. (We checked 

 and compared these carefully with the specimens at our com- 

 mand before coming to any conclusions). By adding the length 

 of the bill to the total length given, we find that the dimensions 

 should then read — 



Total length, 184 mm.; culmen, 14 mm.; wing, 165 mm.; tail, 

 70 mm. ; tarsus, 35 mm. ; middle toe without claw. 18 mm. ; with 

 claw, 21 mm. 



These readjustments bring the measurements into line with 

 those already published, and so give a better basis for com- 

 parative work. We believe that the above figures are the first 

 ever |)ublished of Vieillot's Type. 



]\Ir. Berlioz further stated that the Ty])e did not carry any 

 indication of Bonaparte. 



We now feel assured that by the publication of this informa- 

 tion, together with the drawings of the type, no doubt should 

 remain as to the validity of Mathews genus Frcf/ettoniis. Fur- 

 thermore, it should greatly assist readers in following the argu- 

 ments set forth in our paper.
