Ocnus panamensis Verrill, 1867, p. 321. — Lampert, 1885, p. 132. — 

 Theel, 1886, p. 116. 



From Verrill's incomplete description it can only be learned that the 

 type measured about 4 cm. in length; the feet were restricted to the 

 ambulacra, in double rows on the ventrum, in single rows toward the
