REPORT OP THE COMMITTEE 
XIII. When an old genus without a specified type has been subdivided 
by a subsequent author, and one of the old species retained 
and specified to be the type of the restricted genus bearing 
the old name, — is it competent for a third author to discard 
this and select another of the original species as a type, when 
by so doing changes are necessitated in nomenclature? No, 
39. Doubtful, 4. No answer, 2. 
XIY. Shall an author be held to have any greater control over or 
greater privileges with relation to names of his own propos- 
ing, after the same have been duly published, than any other 
subsequent author? No, 40. Doubtful, 2. Yes, 2. No 
answer, 1. 
XV. For instance, when an author describes a genus and indicates a 
species as its type, is it allowable for him subsequently to 
substitute any other species as a foundation for his genus, or 
to use the original type as a foundation for another new 
genus? No, 38. Doubtful, 1. Yes, 2. No answer 4. 
XYI. If an author describes a genus and does not refer to it any then 
or previously described existing species, can the genus be 
taken as established? No, 33. Doubtful, 7. Yes, 1. No 
answer, 4. 
XYII. If an author applies a specific name to an object without refer- 
ring it to some then or previously described genus, is the 
specific name entitled to recognition by subsequent authors? 
No, 33. Doubtful, 4. Yes, 7. No answer, 1. 
XYIII. When a generic name has lapsed from sufficient cause into 
synonymy, should it be thenceforth entirely rejected from no- 
menclature? or should it still be applicable to any new and 
valid genus? Reject, 19. Accept, 23. Doubtful, 1. No 
answer, 2. 
XIX. Should a name which has been once used in one subkingdom, 
and has lapsed into synonymy, be considered available for use 
in any other if not entirely rejected from nomenclature? N o 
20. Doubtful, 1. Yes, 18. No answer, 6. 
XX. Should a name be liable to be changed or a later one substituted 
for it, if the original be supposed to be inapplicable or con- 
tradictory of the characters of the species or genus to which 
it was applied? No, 28. Doubtful, 3. Yes, 13. No answer, 1. 
Example . A fish without teeth was named Polyodon which 
name had come into use; when a later author substituted 
Spatularia on the ground that Polyodon was inapplicable.
