40 BULLETIN 84, UNITED STATES NATIONAL MUSEUM. 



There is now a second question of denomination to be discussed, namely, that 

 referring to the Amphiodia which Liitken successively designated as cordifera 

 and riisei. I have had in hand Liitken's type with the label in this naturaUst's 

 own handwriting, and this label reads exactly: "Amphipholis. — Ampliiura Riisei 

 Lutken=^. cordifera Liitken." It seems therefore that the name of riisei was 

 preferred by him, and considering also that the name cordifera might lead to con- 

 fusion, I feel rather inchned to adopt the former, for, in my opinion, the rule of 

 priority must not be applied with such strictness as to procure inconveniences or 

 faciUtate errors. Besides, I beg to point out that the term cordifera has been 

 employed only by Ljungman (71, p. 647), who classified this species in the genus 

 AmpMpJiolis, but the very few authors who have written about it since, such as 

 Ludwig in 1882 and H. L. Clark in 1901, have designated it under the name of 

 riisei. The same denomination was adopted also by Lyman in 1875 (75, p. 128) 

 and in 1882 (82, pp. 125 and 146).
