where they meet the apex of the parapodial trunks. These black spots Monro called rosette glands. 

 From the third foot backwards, there is a ventral chromophil gland in the neuropodia. There is a 

 prominent tail carrying rudimentary feet. 



Discussion. The black spot described by Monro as a rosette gland bears no resemblance to described 

 rosettes, nor does it have any of the fine tubules normally associated with hyaline glands. It is 

 probably advisable to separate it from the hyaline organ, but to call it a rosette over-emphasizes the 

 difference, and tends to hide the close relationship of T. kempi to T. nisseni and T. krampi.

Description. In Table 8 measurements for ten of the twenty-five specimens examined have been 

 listed, including the smallest and largest.

There is a small indentation in the middle of the anterior border of the antennae. A pair of eyes is 

 present on the prostomium but the eyes are rarely distinct. The first pair of chaetigers is small, the 

 second pair extend to about two-thirds the length of the body. One rosette is present near the ventral 

 surface of the parapodia of each of the first two feet ; thereafter one is present on all notopodial and 

 neuropodial pinnules where they meet the apex of the parapodial trunk. The characteristic ' spur ' 

 glands of the species may appear on the first neuropodia, projecting prominently from the ventral 

 border of the pinnules ; they are always present from the second feet onwards and from the third are 

 associated with the large chromophil glands. In the larger specimens, both spur and chromophil 

 glands are so close together that they appear as one, with the spur represented as an outgrowth 

 breaking the ventral surface of the pinnule. A prominent tail is always present and with it are 

 normally associated rudimentary parapodia. 



General distribution. T. apsteini has its southern limit of distribution in the Atlantic Ocean at the 

 Sub-Tropical Convergence (see p. 252).
