McMurrich. Mr. Kofoid, of Ann Arbor, will prepare a paper on 

 the interesting group of Solenogasteridas based upon material col- 

 lected by the " Albatross" both in the Atlantic and in the Pacific. 

 The Atlantic species have been intrusted to Mr. Kofoid by Professor 

 Goode of the National Museum. 



We have to thank Professor Mendenhall of the Coast Survey, 

 and Commander Sigsbee of the Hydrographic Office, for charts, 

 and for other assistance connected with my expeditions to the 

 Bahamas and to the Bermudas. To Professor George Davidson 

 we are indebted for a specimen of trachyte from Clipperton Island, 

 and for a sketch of that atoll. To Captain Wharton of the 

 British Hydrographic Office I am also indebted for information 

 regarding some early charts of the Bahamas, and to Captain Barr, 

 R. N., and to the Hon. A. Allison for assistance during my visit 

 to the Bermudas. 



Among our most important acquisitions I may mention a col- 

 lection of birds from the "Albatross" Expedition of 1891, collected 

 at the Galapagos, and determined by Mr. Robert Ridgway, and a 

 general collection of shells, presented by the family of the late 

 William M. Wheildon of Concord, Massachusetts. 



From the United States Geological Survey, through the National 

 Museum, we have received a fine slab of Climactichnites Youngi, 

 and some interesting fossils have been purchased from Mr. Charles 

 Sternberg. From the Royal Museum of Brussells we have received 

 an admirable cast of an Iguanodon, which we propose to mount as 

 the central piece of the Jurassic Exhibition Room. We are in- 

 debted to Professor Dupont for the great trouble he took in 

 making the arrangements necessary to procure this cast. 



Mr. C. B. Riker has sent us an important series of borings 

 from an artesian well on Port Royal Spit, Jamaica, which passes 

 through the coral reefs of the Point. It is interesting to note 

 that a preliminary examination of the specimens indicates a very 

 moderate thickness of reef rock resting upon the older limestones. 



To Professor Yerrill we are indebted for sending us a series 

 of corals collected by Professor Gabb from the elevated reef of 

 Santo Domingo, for comparison with the species collected at vari- 

 ous points of the elevated reef of Cuba during the " Wild Duck " 

 Expedition. None of the species examined appear to differ from 

 the Cuban types, and they also appear to be identical with species 

 now living in the West Indian seas. To Dr. Dall we are indebted
