38 REPORT OF NATIONAL MUSEUM, 1910. 



On account of lack of sufFicient space, it has been impossible to 

 accomplish much in the direction of separating and preparing the 

 extensive reserve and unstudied collections, many of which have 

 been stored for a long time in inconvenient places, preparatory to 

 their removal to the new building. The corals not on exhibition have, 

 however, been transferred. The dried sponges, which have been 

 distributed in several places, were segregated on one of the galleries 

 in the mam Smithsonian hall, w^hile another gallery was fitted up as a 

 temporary laboratory for work on the extensive collection of crinoids. 

 Through the temporary employment of several persons, more than 

 the customary amount of routine work was accomplished. One such 

 person of the grade of aid made considerable progress in the sorting 

 of miscellaneous material. The others were engaged in recording 

 and cataloguing, a work which, by force of circumstances, has fallen 

 greatly in arrears and should be brought up to date as soon as possi- 

 ble This was done during the year for the identified specimens of 

 crustaceans, bryozoans, tunicates, and ophiurans. 



Through an oversight, the last report failed to make mention of 

 the investigations conducted by the staff of this division during 

 1908-9, which are therefore mcorporated in the following summa- 

 tion for the past year. Miss M. J. Rathbun, assistant curator, com- 

 pleted her studies on the crabs collected in the Gulf of Siam by Dr. 

 Th. Mortensen, of Copenhagen, and in the Indian Ocean by H. M. S. 

 Sedlark on the Percy Sladen Trust Expedition of 1905 under Mr. J. 

 Stanley Gardiner, The report on the former is in course of pubh- 

 cation in the memoirs of the Royal Danish Academy of Sciences, while 

 that on the latter will appear in the Transactions of the Linnean 

 Society of London. Other investigations finished by Miss Rathbun are 

 incorporated in a report on the decapod and stomatopod crustaceans 

 of the coast and fresh waters of Peru, collected by Dr. R. E. Coker 

 and submitted to the Museum by the Peruvian Government for 

 working up, now being printed m the Proceedings of the National 

 Museum; in a paper on a small collection of decapod crustaceans 

 obtained by Mr. Thomas Barbour in the Dutch East Indies, British 

 India, and Japan in 1906-7, to be published in the Bulletm of the 

 Museum of Comparative Zoology; and in an account of the decapod, 

 scliizopod, and branchiopod crustaceans contained in the large 

 collection of natural history secured by Mr. Owen Bryant during his 

 Labrador trip of 1909, which will be published in the full report of 

 the cruise. The localities for each species of the collection last men- 

 tioned have already been given in a list of the crustaceans of Labra- 

 dor, which forms an appendix to Dr. Grenfell's recent book, entitled 

 "Labrador." 



Mr. Austm H. Clark continued liis researches on the crinoids, and 

 has the first part of au extensive monograph of the group nearly
