 Fishes. 



The late Professor F. M. Balfour has published, in connection 

 with Mr. Parker, in the Proceedings of the Royal Society, a pre- 

 liminary account of the Embryology of Lepidosteus based upon 

 the material sent him from our Museum. Professor Mackintosh 

 has completed his examination of the large series of sections of 

 spines of sea-urchins sent him by the Museum. His Report has 

 been sent for publication in the Memoirs of the Royal Irish 

 Academy of Dublin. ^ 



The arrangement of the new rooms which have become availa- 

 ble for exhibition and for storage has made excellent progress. 

 All the material temporarily stored in the exhibition rooms has 

 at last been removed and distributed to its final position, so that 

 we may now hope within reasonable time to open all our Zoologi- 

 cal Exhibition Rooms to the public, even should they not exhibit 

 all the specimens we expect to place in them. 



The greater part of the gallery of the Systematic Collection of 

 Mollusks has been arranged, and Messrs. Hamlin and Hyatt hope 

 to finish the work on the Mollusks during the coming year. The 

 Systematic Collection of Fishes is now on exhibition and com- 

 prises the typical forms of the recent bony fishes, of the Selachians 

 and of the Ganoids. It only remains now to intercalate the 

 blanks and many of the fossil forms to complete this room. 



The Systematic Collection of Birds is undergoing its final 

 arrangement. A large part of the faunal collections intended for 

 the Indian and Australian rooms has been placed in their exhi- 

 bition cases, so that these rooms also can probably be open to the 

 public during the coming winter. Fair progress has likewise been 

 made in the African faunal collection. The skeletons of the 

 reptiles, fishes, birds, and mammals, have been placed in the 

 storage rooms destined for their use. The workroom containing 

 the corals, polyps, echinoderms and sponges has been partially 

 occupied, and Mr. Fewkes has arranged in the Systematic Room 

 of Radiates a selected collection of Alcyonoids. 



Mr. Garman has continued the explorations made by him 

 during the two previous years, and has brought together an enor- 

 mous collection of mammalian remains, — one of the finest, in- 

 deed, ever brought from the West. The thanks of the Museum
