ALCIOPIDAE 79 



Lopadorhynchus krohnii (Clap.), var. simplex, var. nov. 



Lopadorhynchus krohnii, Fauvel, 1923, p. 185, figs. 68 a-d, with synonymy. 



St. 104. 31.X.26. 41" 33' 30" S, 17° 58' 00" W. 56(-o)m. Gear N 100 H. Two specimens. 

 St. 267. 23. vii. 27. 24" 31' 00" S, 12° 15' 30" E. 45o-55o(-o) m. Gear TYF. One specimen. 

 St. 268. 25. vii. 27. 18° 37' 00" S, 10° 46' 00" E. 100-150 (-0) m. Gear TYF. One specimen. 



Remarks. These specimens, measuring about 9 mm. by 3 mm. 

 including the feet, correspond in detail to Fauvel's description 

 except in the following particulars. There are no simple bristles 

 behind the 2nd chaetiger. The 3rd chaetiger (Fig. 23, a) has 

 the aciculum produced into a slender tip extending well beyond 

 the lips of the chaeta sac. Posteriorly to this the aciculum is 

 normal and the bristles (Fig. 23,6) are all compound. I can 

 find no trace of a ventral cirrus in the first two chaetigers.

Family ALCIOPIDAE 



Remarks. Apstein (1900) and Fauvel (1923) have both given admirable accounts, 

 with synonymies, of the majority of the species belonging to this family. When I have 

 nothing to add, I shall do no more than give the references to the descriptions of these 

 authors under the specific names.
