Figure 76. — Cnemidocarpa areolata (Heller); a, whole specimen; b, left half of mantle 

 body, inner side; c, right half of same; d, ciliated groove; e, atrial tentacles. 



Remarks. — The elongated appearance of the present specimen, being 

 much extended in the anterior half of the body, is unusual for 

 Cnemidocarpa areolata; the gonads seem to be relatively fewer than 

 usual. But without doubt this is a small individual of G. areolata^ as 

 the details of the internal structure conform exactly to those of the 

 typical form of the species.
