I. NOMENCLATURE OF HYBRIDS. 
1. (a) In the naming of hybrids the name of the male 
should preceed that of the female, and be united with the lat- 
ter by the sign of multiplication. The use of the astronomical 
signs to indicate sex can be dispensed with. Of the two ex- 
amples following, either can be used, as Capra hircus $ X Ovis 
aries 9 , or Capra hircus X Ovis aries. 
(b) Another method can be employed for this purpose. The 
two names can be represented as is a fraction, the name of the 
male forming the numerator, and that of the female the de- 
nominator, as Owais. This second method possesses the 
advantage that the name of the observer can be indicated 
whenever such indication is desirable, as ierosmes ^ Rabé. 
(c) The second method should be employed where either 
one of the parents is a hybrid, as Gaius gaiinaseus — s 
(d) In ease the parents of a hybrid are unknown, it pro- 
visionally takes a simple specific name like a true species, but 
the generic name is preceded by the multiplication sign, as 
x Salix erdingeri Kerner. 
II. Generic NAMES. 
2. Every foreign word employed, either as a generic or 
specific name, should retain the meaning it has in the lan- 
guage from which it is taken, if in this language it denotes an 
organized being, as Batrachus bdetta. 
III. Sprecirric NAMES. 
3. The geographical names of uncivilized countries, and of 
such peoples as do not use the Latin alphabet, should be tran- 
! The E" part of these rules was published in the AMERICAN NATURALIST for
