in hand a final memoir on the Crustacea of the " Blake." This 

 leaves still to be published, of the work on the " Blake " collections, 

 the memoir on the Alcyonaria, by Professor Verrill ; the Deep- 

 sea Fishes, by Professor Goode and Dr. Bean ; the Comatulse, by 

 Dr. Hartlaub ; and a memoir on Pentacrinus, by Professor H. 

 Ludwig. 



Although not published under the auspices of the Museum, I 

 should mention as forming a part of the results of the " Blake" 

 an important paper by Dr. Wiren, on Solenogaster, a great part 

 of which is based on specimens dredged by the " Blake " in 168 

 fathoms off St. Lucia, in the winter of 1878-79, issued in the 

 Memoirs of the Stockholm Academy of Sciences. 



The available bulk of our Pentacrinus material has been sent to 

 Professor Ludwig of Bonn, who has kindly consented to work up 

 this genus from the collections made by the " Blake " in the West 

 Indies. 



A number of publications are in preparation in the different 

 Laboratories of the Museum. The following work has been done 

 during the past year on the Collections of the Fish Commission 

 Steamer "Albatross " expedition of 1891. Mr. Westergren has 

 nearly completed the plates (fifty in number) which are to accom- 

 pany Professor Faxon's memoir on the Crustacea of the expe- 

 dition. Mr. Faxon has already completed the text, and a 

 preliminary report of the collection has been published in the 

 Bulletin, awaiting the preparation of the plates for the final 

 monograph. 



Professor Ludwig also reports that he has completed the 

 monograph on the Holothurians. A preliminary notice was pub- 

 lished in the Zoologischer Anzeiger and in the Museum Bulletin. 

 Professor Ludwig states that his report is to be illustrated by 

 nineteen plates in all, of which eight will be colored plates. The 

 plates are distributed among different families as follows : Synal- 

 lactinas, one plate ; Psychropotinae, five plates ; Deimatinse, five 

 plates ; Elpidiinse, one plate ; Dendrochirotae, two plates ; Mol- 

 padiidas, three plates ; Synaptidae, one plate ; and Pelagothuriidae, 

 one plate. The whole of his manuscript has been received, and 

 the last plate is in the hands of Werner and Winter. 



Professsor Schimkewitsch has sent in a report on the Pycnogo- 

 nidse accompanied with two plates, Dr. W. McM. Woodworth a 

 Report on the Planarians, with one plate and Professor S. F.
