PHYLLOPOD CRUSTACEA 55 



Apits caiicnfomns Scliaeffer 

 1756 Apiis cancrifonnis Schaeffer. Der krebsartige Kiefenfuss, etc. 

 Locality: Punjab: Sargodhar District, 3 mi. South of Nuriwala. 29 9. 6-III-32. 

 Reported from : Europe, Northern Africa. Kashmir (sec. Barnard). 



Carapace oval, shghtly longer than broad. Nuchal organ (between the posterior margins 

 of the compound eyes) oval as seen from above, conical as seen from the side. Number of 

 postpedigerous segments in S 6-8, in 9 5-8. Fourth endite of 1st leg longer than carapace. 

 Rami of caudal furca as long as all the rest of the animal, or longer. 



The 2 ? 9 of the collection have 8 postpedigerous segments each — an unusually large 

 number. The other characters agree so well, however, that there is no doubt of the correct- 

 ness of the identification. (See Figure 16, drawn by Miss L. Krause.) In nothern Europe 

 this species is generally parthenogenetic. Whether this is true in this Indian locality the col- 

 lection is too small to show. 



On various bases this species has been divided into a number of subspecies, but as Barnard 

 (1929) has so clearly shown in his study of the South African forms, the diagnostic char- 

 acters chosen have no taxonomic value and simply result from individual variation (Cf. also 

 Gurney (1923)). India may or may not harbor a valid subspecies, but this can only be deter- 

 mined by a study of some hundreds of specimens.
