The spermatophorcs would seem to he discharged hy the 

 male at the vulwc of the female, one or more becoming 

 attached thereto and fertilizing the ova as they pass, or other- 

 wise. Whether the male secretes new spermatophores and 

 repeats the process of fertilization could not he determined. 



It is interesting that the South African form so closely agrees 

 with the Sdbc'lh'pln'his .Sc//.s// of Claparede from the Mediterranean 

 Spirognipliis SpuUcuizani. The proportions of the antenules 

 and of the antennae differ, as \\ell as the number of the ter- 

 minal hooks in the latter. Moreover, in his figure he shows 

 only three caudal segments behind the genital (the first having 

 apparently been joined to the genital). 



The following note by Mr. Andrew Scott on the Family, and 

 the remarks of Dr. Thomas Scott, after consideration of all the 

 features of the case, are of special interest in connection with 

 this ectoparasite. 



The Family ScippliiriiiidiV, which nicludes the genera Pscii- 

 daitthc'ssius, Licliojiiolgiis, HcdnianiicUa, and SabellipJii/.is, and 

 the Family Ergasilidcv, containing such genera as Ergasilus, 

 Bomoloclins, etc., are founded chiefly on the structure of the 

 cephalic appendages, especially the mandible. 



In the Sappliiriiiidiv the mandible is in the form of a thin 

 plate, with a more or less distinctly serrate edge. The mandible 

 in the Ergasilidiv is jointed, and terminates in a strong tooth, 

 with a serrate edge. 



The genera Psciiddiif/u'ssiiis, Lichoiuolgiis, and Hedmaiinclla 

 are distinguished by the structure of the inner branch of the 

 fourth pair of swimming feet. In Pscndaiithcssius the inner 

 branch is one-jointed ; in LicJiomolgiis, two-jointed ; and in 

 Hcdiiiaiinclla, three-jointed. The other appendages are very 

 much alike in the three genera. 



Sabellipliilns is ^ep'ciY^xted on account of the structure of the 

 second maxilliped of the female. In Pscudanthessins, Licho- 

 fnolgus, and Hcduuinuclla the female second maxilliped ter- 

 minates in a short, almost obsolete claw. In SabcUiphilits the 

 maxilliped is well developed, and terminates in a long, strong 

 claw. 



Dr. Scott observes that this crustacean certainly belongs to 

 the Sapphirinidce (= the LicJioiiiolgida- of Brady and others). 

 It does not agree with SabcUiphiliis in the structure of the 

 antennule, and to some extent in the structure of the first and 

 second maxillipedes, and especially in the structure of the 

 endopodites of the fourth pair of the thoracic legs. In Sabclli- 

 pliilus the first two joints of the antennules are considerably 

 dilated, and the endopodite of the fourth pair of legs are three- 

 not two-jointed. On the other hand the specimens from South 

 Africa — in the structure of the antennules, and especially in the 

 structure of the endopodite of the fourth pair of legs- -agree
