Ammotrypane buitendijki n. sp. Fig. 3. 



A specimen in a rather indifferent state of preservation; it measures 

 40 mm. in length and is provided with 64 pairs of parapodia, a number 

 greater than in any species hitherto known. No in- 

 tersegmental grooves are visible. The head is furnished 

 with a conspicuous palpode. Commencing with the 

 2 nd setigerous segment each parapodium is provided 

 with a long, cirriform branchia,. bending along the 

 lateral side of the body and reaching to the median 

 dorsal line; in the posterior segments the branchiae 

 gradually grow shorter. The parapodial lobe has a 

 slender, conical shape and in the anterior body-region 

 measures about a tenth of the length of the branchia; 

 in the posterior segments however it grows longer 

 and attains a third of the branchial length. A short, cylindrical, ventral 

 cirrus is present, measuring in length a third of the parapodical lobe. 

 The anal tube is a slender, gutter-shaped appendage, provided with rather 

 long cirri along its border; at its base a couple of long cirri occurs.
