bin! is Lnfresnaye's P. (liaholica. ('oinputiiii; Kiihl's measurements 

 of /*. hot»itatii on the basis of the "Pied (hi Roi " and tlie " Frankfiu-t 

 A. M. inch," and assuminj; that Knhl, as a student of Tenuninck, used 

 the French system of measurements, he comes to the conclusion that 

 Kuhl's P. liiuitHatn apphes to the smaMer bird and accordingly re- 

 stricts the name in that sense. 



Fortunately Kuhl's type is available to-day in the Leyden ^Museum. 

 It was listed with another specimen by Schlegel (Mus. Pays-Bas. 

 Mon. Procellariae, 1803. p. 13) imder the name ProccUaria haesitafa 

 Kuitl. Sciilegel gives measurements of both specimens, wliich indicate 

 a large bird. 



Dr. E. D. Aan Oort of the Leyden Musemn, at oiir request, has very 

 kindly examined Kuhl's specimens, and writes us as follows: — 



"There are in the collection of our INhiseum two specimens of 

 Acstrelata hacsitata (Kuhl), both originally labelled by Temminck: 

 Procellaria hasitaia, ^lers de I'lnde. They are both the types of 

 ProccUaria hacsiiaia Kuhl (Beitr. 1820, p. 142) and of ProccUaria hasi- 

 taia in Temminck's PI. col. V, 1826, pi. 416. Temminck's plate, 

 however, is not correct, the upper tail coverts, as well as the under 

 tail coverts, being pure ichite, not grey. The two specimens are 

 exactly alike. Schlegel mentions these in his catalogue of the Pro- 

 cellariae (Mus. Pays-Bas, Proc, ProccUaria hacsitata, p. 14) but he 

 wrongly designates only Xo. 1 as the type of the species, and changes 

 Temminck's locality "Mers de ITnde" into "Ocean." 



"The measurements of the two specimens are: — 



Schlegel's Cat. No. 1 No. 2. 



" In my opinion hacsitata and diabolica are the same." 

 It is evident from the above that Kuhl's cot^pes are both large 

 birds agreeing very well in size with the types of P. diabolica, except 

 that the wing measurement is even greater. We agree with Dr. 

 van Oort that /■'. hacsitata Kuhl and P. diabolica Lafresnaye are the 

 same. Obviously the name hacsitata should be used for the species.
