For this reason, we examined specimens deposited in the MNCNM, collected and reported by San Martín & Parapar (1997). These specimens agree with the previous descriptions, except for the absence of dorsal cirri on chaetiger 2 (Figs 4A, 5A); this character is described in the previous descriptions but in Benham 1921, fig. 11, the drawing shows dorsal cirri on chaetiger 2; at that time, the importance of the presence or absence of dorsal cirri on chaetiger 2 was not known to separate species of Exogone , and usually they were figured although not present. The compound chaetae are all thick, with distally enlarged shafts and numerous distal and subdistal spines (Figs 4C, E, G), and very short, almost included inside the distal, spinose part of the shafts, named as “gomphotric chaetae” by Benham 1921, 1927. The dorsal simple chaetae are the typical of the genus (Figs 4B, F, 5B, C, E), but some in the mid-body are distally enlarged, and having a spatulate appearance (Fig. 4D). Apparently, this species lacks ventral simple chaetae, since they have not been described by any author and we have not found these in the material ...
