Amphistegina vulgaris, d'Orb., was adopted by Parker and Jones as the natural 

 type of the genus (see references given above) ; and, moreover, it has priority as a 

 published form (Modele, No. 40 in livraison 2) over A. Lessonii (Modele, No. 98 in 

 livraison 4), although the latter comes first in d'Orbigny's catalogue in the ' Annales 

 Sci. Nat.,' vol. vii, p. 304, and has therefore been regarded as the "type" by 

 various writers. Besides A. Lessonii several other varieties are enumerated in 

 Brady's list of synonyms in the ' Challenger ' Report, pp. 740, 741. All of these 

 and others can be grouped around A. vulgaris as indicated by Parker and Jones in 

 1863 and 1865 on zoological grounds. 



The following are the most important references to Amphistegina since the 

 publication of the ' Challenger ' Report, 1884, or not included in it.
