from two to four additional teeth spaced down this margin. The 

 complex spines are all of this pattern, differing only in the degree 

 of length, the more dorsally situated setae being the longer, both 

 in the proportions of the shaft and the distal blade. 



This annelid takes its specific name from the fancied resem- 

 blance of its colour pattern of mottled chocolate brown on a 

 creamy groundcolour to that of a panther. The Tahiti specimen 

 retains such a colour design on the dorsal and lateral surfaces, the 

 cirri being entirely cream, as is also the ventral surface. This 

 striking colour pattern of the annelid blends with its normal habi- 

 tat beneath the sun-flecked, moving waves and shifting sands to 

 render the annelid inconspicuous in the coral reef crevices or 

 muddy tide pools it frequents.

Type : Kinberg's type specimen came from the Society Islands 

 and was deposited apparently in the Royal Zoological Museum of 

 Stockholm. 



Distribution : In addition to the type locality, Augener has 

 described P. ovalifera from Australia, which is doubtfully con- 

 sidered synonymous with gracilis, and more recently Fauvel has, 

 with expressed doubt, referred a specimen from the Andamans to
