SUMMARIES OF SIX OPINIONS (9, 11, 13, 

 15, 17, IS) BY THE INTERNATIONAL 

 COMMISSION ON ZOOLOGICAL 

 NOMENCLATURE 

 The following summaries of recent opinions 

 by the International Commission on Zoological 

 Nomenclature are published for the informa- 

 tion of persons interested in the points in 

 question. It is expected that the full details 

 of the arguments will be published later in 

 connection with certain other cases now under 

 consideration. These summaries do not give 

 the reservations made by certain commission- 

 ers, but these reservations will be presented in 

 the final publication. 



9. The Use of the Name of a Composite 

 Genus for a Component Part requiring a 

 Name. — The decision as to whether the name 

 of a composite genus, when made up wholly 

 of older genera, is tenable for a component part 



requiring a name, depends upon a variety of 

 circumstances. There are circumstances under 

 which such name may be used, others under 

 which it may not be used. (Art. 32.) 



Vote: Affirmative, 12; negative, 0; not 

 voting, 3. 



11. The Designation of Genotypes hy La- 

 treille, ISIO. — The " Table des genres avec 

 I'indication de I'espeee qui leur sert de type," 

 in Latreille's (1810) " Considerations gen- 

 erales," should be accepted as designation of 

 types of the genera in question. (Art. 32.) 



Affirmative, 11; negative, 1; not voting, 3. 



13. The Specific Name of the Sand Crab. — 

 Catesby's (1743) prelinnsan name arenarius is 

 not available under the code, although " re- 

 printed " in 1771 ; quadratus 1793 is stated to 

 be preoccupied; albicans 1802, being the next 

 specific name in the list, becomes valid, under 

 the premises submitted. 



Affirmative, 10; negative, 0; not voting, 5. 



15. Craspedacusta sowerbii Lankester, 1880, 

 n. g., n. sp., vs. Limnocodium victoria Allman, 

 1880, n. g., n. sp. — Craspedacusta sowerhii Lan- 

 kester, 1880, June 17, has clear priority over 

 Limnocodium victoria Allman, 1880, June 24. 

 Presentation of a paper before a scientific 

 society does not constitute publication in the 

 sense of the code. The cormnission is without 

 authority to sanction usage in contravention 

 to the provisions of the code. 



Affirmative, 15; negative, 0. 



17. Shall the Genera of Weber, 1195, he 

 Accepted? — Weber's "Nomenelator entomolo- 

 gicus," 1795, complies with the requirements 

 of Article 25, hence the genera in question are 

 to be accepted, in so far as they individually 

 comply with the conditions of the code. 



Affirmative, 11; negative, 1; not voting, 3. 



18. The Type of Hydrus Schneider, 1799, 

 SS3. — On the basis of the premises submitted 

 by Dr. Stejneger, Hydrus caspius Schneider, 

 syn. Coluber hydrus Pallas, is the type of 

 Schneider's genus Hydrus, according to Ar- 

 ticle 30 (d). The fact that Schneider refers 

 to the page and number of this species estab- 

 lishes the point in question and the fact that 

 the name Coluher hydrus was not quoted is
