We have applied Chun's name Abylopsis quinctinx to those Abylids^ which are of small 

 size and which differ from the Abyla pentagona in many other respects. Chun writes 97 a (p. 29): 

 "Ich habe neuerdings Gelegenheit gefunden, dieselbe (that is Abylopsis quincnnx Ch.) eingehender 

 "zu untersuchen und finde sie nur in feineren Punkten, vvelche immerhin eine specifische Tren- 

 "nung rechtfertigen, verschieden". 



We find that these minor details are not so inconsiderable as Chun supposes and we 

 mean to show that the differences between Abyla pentagona and Abylopsis quinainx are in 

 fact very important. The figure given by Chun 97 b shows at first sight striking differences 

 with the Abyla pentagona O. et G. 



Abylopsis quincunx was represented by 6 complete specimens, 125 loose superior and 

 35 loose inferior nectophores. 



When comparing the list of stations of Abyla pe7itag07ia and of Abylopsis quincnnx we 

 see that at 1 5 stations of the former the latter appeared too, so that they may be said to 

 appear frequently together. Abylopsis qziiticunx is very small (complete specimen length not 

 quite 6 mm.) and absolutely transparent but for the calcareous granules in the somatocyst of 

 the superior nectophore. The two figures (PL III, figg. 22, 23) of the complete Abylopsis 

 quincunx show, at the first view how different the outward appearance is between Abylopsis 

 and Abyla, especially as far as the inferior nectophore is concerned; not only its size in relation 

 to the superior one, but also its shape. 

 Superior nectophore. 



We intend to compare alternately a superior nectophore oi Abyla peJitagona and a superior
