Invertebrate Fauna of the Firth of Forth. 307 



No. 6. Fork-tailed Petrel. 



Caught whilst trying to alight on the rail beside the light on the oast side 

 of the lantern about midnight. The stomach contained nothing but an oily 

 substance (Geo. Sim, Aberdeen, in lit.). The specimen was preserved for 

 ' ' a gentleman in London " by Mr Geo. Sim, 



Caught by Mr M'Alister ; recorded by J. A. H.-B. 



Note. — The lately discovered breeding-place of this species — North Rona — 



may possibl}' have been (?) the starting-point of this specimen. — J. A. H.-B. 



The absence of notes in two of our columns is to be regretted, but it is 



hoped that our lighthouse reporters will atteiul better to these data in future. 



The schedules show signs of improvement annually. 



John A. Harvie-Brown, 



Member of Committee on Migration of Birds, 



British Association, 1879-1885. 



XXIII. Recent Additions to the Invertebrate Fauna of the 

 Firth of Forth. By J. E. Henderson, Esq., M.B., 

 Scottish Marine Station, Granton. 



(Read 17th December 1884.) 



The following species of invertebrates, which I am about 

 to submit to the members of the Eoyal Physical Society, 

 have not previously been recorded from the Firth of Forth. 

 With the exception of a few which have lain unidentified in 

 my collection for a year or two, they have all been taken 

 since last August, when I commenced to work at the Granton 

 Marine Station, where tlie facilities for collecting are of a 

 high order. The record of Firth of Forth invertebrates is 

 still very incomplete, and much work must be done in 

 many of the groups — more especially the Sponges, Worms, 

 Crustacea, and Polyzoa — before the list can be said to be a 

 full one. 



Most of my attention having been devoted to the Crustacea, 

 the largest number of additions occurs in this group ; and as 

 both Mr Cunningham and I have made extensive gatherings 

 of Copepoda, etc., I hope yet, if possible, to form lists of 

 these more minute, though not less interesting, organisms. 

 My warm thanks are due to the Eev. A. M. Norman, D.C.L., 

 for kindly examining many of the species in the list, — espe- 

 cially among the Crustacea, — and also for many useful hints 

 on the identification of marine invertebrates.
