 Esq. 



In the young plant the asci are precisely of the form of those 

 of Choiromyces mceandriformis, but with age they enlarge, and are 

 at last obovate as in Tuber cestivmn. Distinguished from the fol- 

 lowing by its smooth pale peridium, and the veins springing from 

 a distinct, generally single basal point.

XLIII. — On the Family Procellaridse, with descriptions of Ten 

 new Species. By John Gould, F.R.S. &c. 



To Richard Taylor, Esq. 

 Dear Sir, 

 There is perhaps no group of birds respecting which so much 

 confusion exists, and the extent of whose range over the sm-face 

 of the ocean is so little known, as that forming the family Pro- 

 ceUaridce ; it may not, therefore, be uninteresting to ornithologists 

 if I furnish you with some observations on and a short account 

 of those species contained in my own collection, which in nearly 

 every instance were procured during my voyage to and return 

 from Australia. I have endeavoured wherever possible to identify 

 them with those described by Forster, Banks, &c., whose draw- 

 ing's and descriptions have been consulted for the pm-pose ; I 

 must observe, however, that the descriptions of Latham and the 

 older authors are in most instances so meagre and confused, that 

 it is quite impossible to decide in every case to which species they 

 have reference, and hence I have been induced in some cases to 

 give new specific appellations to birds which may have been de- 

 scribed by them, but which it is impossible, for the reasons above 



given, to identify. 



I am, Dear Sir, your obedient servant, 

 April 17th, 1814. JoHN GoULD. 



Biomedea exulans, Linn. — This species is very numerous be- 

 tween the 30th and 60th degrees of S. lat., and is to be met with 

 in every part of the circle encompassing the world bounded by 

 those degrees ;, its range, however, extends much farther south, 

 even to within the Antarctic circle. 



Diomedea cauta,Gou[d,lh-oc. of Zool. Soc. part 8. p. 177. — Very 

 abundant off the southern coast of Van Diemen^s Land. I shot 

 several specimens in the neighbom-hood of the whaling station in 

 Recherche Bay, where they were feeding upon the olfal of dead 

 i'Ctacese.
