d'Orbigny's Rosalina vilardehoanci, as a comparison of the two will at 

 once show. 



From another station off Jolo, D5546, in 138 fathoms (252 meters), 

 is a specimen which might almost have served for the original of 

 Brady's plate 86, figure 9. This form is referred to D. mediterranen- 

 sis d'Orbigny by Heron-Allen and Earland, but does not seem the 

 same as their figured specimens from Clare Island.
