the world, but there is no catalogue and the number is not known, even 

 approximately. The New York vState Museum at Albany possesses a 

 large number of types under the care of the State Entomologist. A 

 catalogue was published in N. Y. Museum Bulletin 141 (1909) pp. 

 119-122, but Dr. Felt informs me that probably about 700 Cecido- 

 myiidas are to be added. Stanford University has about 500 types, 

 the majority Mallophaga.* 



There are some very large private collections, such as those of Dr. 

 William Barnes at Decatur, Illinois, (890 types). Dr. Nathan Banks at 

 East Falls Church, Va., (about 1500 types and about 300 cotypes or 

 paratypes) and Col. Thos. L. Casey. In the above estimates cotypes 

 or paratypes are in nearly every case reckoned as types. 



Opinions on the Location of Types. We have sought to ascertain 

 the opinions of representative entomologists regarding the location of 

 types, and cite the following as examples : 



"We believe that privately owned types should eventually go to 

 some good museum." — H. Skinner. 



"I consider it unwise to make any suggestion as to restricting types 

 to certain institutions. " — S. Henshaw. 



"I believe that it should be the policy of authors to place their types 

 where they will be cared for in the future. " — W. J. Holland. (See also 

 The Conservation of Types, First International Entomological Congress, 

 p. 366, where six museums are named as the only ones in the United 

 States to which types should be consigned) . 



"I do not believe that types should remain permanently in private 

 collections." — ^W. M. Wheeler. 



" I do not see how any fixed rules regarding the distribution of types 

 can be made, nor can we prohibit them from being private property. 

 With many a zoologist his collection and books are his only assets, and 

 while he is working they are probably doing as much good in his own 

 collection as in a public museum. When I am through with my col- 

 lection I want it to go into the hands of a dipterist. " — C. W. Johnson. 



"It would be of course a very good thing to have the types in a 

 limited number of public institutions, or still better in one only, but I 

 am afraid this ideal condition will never be reached. In regard to a 

 privately owned type, I am of the opinion that as soon as a new species 

 is described the type becomes public property, and the author, if he 

 keeps it in his own collection, should take great pains to keep the type 

 safe and in good condition, and provide sooner or later for a resting 

 place in a public institution. " — Chas. Schaeffer. 



"Personally I am inclined to the view, that types ought to be 

 restricted to as few institutions as possible. As to the number of these, 

 or how they should be selected, I have no opinion. " — S. Graenicher. 



"We deposit all particularly perishable types (such as pinned 

 insects) in the U. S. National Museum." — A. G. Ruthven, Head 

 Curator, University of Michigan Museum. 



* Since the report was read, the University of Kansas has reported the pos- 

 session of 897 types and 36 cotypes, etc. The University of Kansas does not loan 

 types.
