she was incapacitated by sickness from continuing her work and the 
collection has this year been without her systematic care. The 
exhibition collections have consequently remained about the same. 
The other parts of this collection have been more or less worked 
over by Miss Isabel L. Johnson. This lady looked over and pre¬ 
pared a large number of fossils, especially crinoids. During this 
work she discovered one of those forms of paleozoic echinoderms 
which are deservedly counted among the most precious treasures 
of even the largest and richest collections. This proved to be a 
new species and Avas described by Dr. Jackson as Lepidesthes wor- 
tlieni. Miss Johnson also did good service in separating and 
arranging odd collections of Mesozoic fossils from Virginia, North 
Carolina, and Pennsylvania, which had not been previously worked 
over. 
A valuable series of Triassic fossils from the Ivlipstein collection 
Avas purchased from Dr. Krantz of Bonn, Germany, and has been 
catalogued and labeled by Miss Martin, avIio has also done other 
miscellaneous work rendered necessary by the absence of Miss 
Ballard. 
Microscopical Collection. 
This collection was carefully inspected by Miss Isabel L. Johnson. 
The Greenleaf, Glenn, and HabershaAV collections were found to be 
in good condition, being mostly composed of dry specimens mounted 
in balsam. The Barnard collection Avas also in fair condition, need¬ 
ing some work; Avliile the Wyman collection, consisting in part of 
wet preparations required more. Thirty-six slides of this last were 
remounted. The collection of sections of skin of cod mounted by 
J. 8. Kingsley was somewhat impaired by time and one or two 
were remounted. Sixty slides of the general collection, Avliich 
needed this radical treatment, Avere also remounted. 
PoRIFERA. 
Considerable work has been done by Mrs. Flint in cataloguing 
the New England collection made by the Curator during his summer 
excursions along our seashores.
