In this " Nachtrag zu den Caprelliden " I cannot find the 

 Latin term Caprellidse anywhere actually used by Dr. Mayer. 

 1903. C, Mayer, Die Caprellidae der Siboga Expedition, p. 3. 



In this and the two preceding works probably everything of 



any importance that has been written on this family down to 



1903 will be found taken into consideration. 



1910. C, Stebbing, Thetis Exp. N.S. Wales, Mem. iv., pt. 5, pp. 629, 



651. 



The words "Family Caprellidae," which should have

 Of this species Dr. Mayer describes on p. 81, " Var. X natal- 

 ensis (pi. 3, figs. 22 and 23). From the Stockholm Museum, 

 collected by Vahlberg in Port Natal, a male about 13 mm. 

 long, quite smooth, only on the fourth segment a postero- 

 dorsal tubercle, which however is sometimes only a little 

 prominent. The front antennae moderately thickened, the 

 flagellum with 13 (in the female 11) articulations ; hinder 

 antennae longer than the combined first and second joints of 

 the front pair. Large grasping hand not setose; venom - 

 tooth proximal ; inner margin of the finger angular. On the 

 perseopods both clasping-spines proximal; truncate spines
