RECOMMENDATIONS. 



Location of Types. It is necessary for the progress of entomology 

 that specialists should frcquenth' have in their possession collections 

 containing many types, and experience shows that so long as these 

 collections are in use the types are reasonably safe and well cared for. 

 Ultimately, however, these types should find a place in some large 

 public museum, where they will be preserved for the use of posterity. 

 If entomologists are expected to make arrangements looking toward the 

 placing of their types in public museums, they have the right to demand 

 that these museums shall be made fully competent to take care of them. 

 Not only must the buildings be practically fireproof, and the cabinets 

 adequate, but there must be a staff large enough to take care of the 

 specimens and keep them in order. Types should never be deposited 

 where a continuous succession of competent curators (entomologists) 

 cannot be depended uix)n. 



Location of Cotypes and Paratypes. New species of insects are 

 frequently described from considerable series of specimens, designated 

 cotypes or paratypes. Authors would probably be glad to distribute 

 some of these among the principal museums or collections, if convenient 

 arrangements existed for doing so. Such distribution would greatly 

 facilitate entomological work, and we suggest the desirability of con- 

 sidering whether some distributing center cannot be organized. 



Location of Types in Collections. We believe that types are best 

 kept in the systematic series, where they can readily be found and 

 compared with their allies. 



Labelling of Types. It is highly desirable that uniform labels 

 should be used for types. Among those submitted for examination, 

 the circular labels with colored margins, from the British Museum, seem 

 to have a sufficient degree of distinctness to enable them to be readily 

 seen, without the rather offensive conspicuousness of some other labels. 

 There should, however, be a place for the type number. 



Cataloguing Types. Every museum should catalogue its types, 

 giving each a number. It is very desirable to publish the catalogue, 

 Avith supplements from time to time. We also suggest that lists of the 

 types received during the year would be useful additions to museum 

 reports, and might well replace some of the worthless information 

 which these usually contain. 



Loaning Types. We are of the opinion that holotypes, or specimens 

 designated as the type should under no circumstances be loaned; but 

 cotype or para type material should be loaned under proper restrictions. 



Permanent Committee. We suggest that the type committee be 

 made permanent, with changing membership, like the committee on 

 nomenclature, and that its members be requested to examine and report 

 on museums and collections as opportunity offers.
