98 Mr. T. D. A. Cockerell — Descriptions and 



within the oesophagus. It must be admitted, however, that 

 the figures accompanying v. Linstow's account are decidedly 

 confusing, and it is not improbable that a failure to recognize 

 the manner in which the entire jaws fold down, like the 

 blades of a penknife, into the oesophagus, has been at the root 

 of the matter. The condition in the present species makes it 

 almost certain that the action of the jaws will be found to be 

 the same in C. viviparus. 



One other point remains to be noticed. It does not seem 

 at all clear that the " kegelformige Spitzen " of v. Linstow 

 are the same as the " papilles ce'phaliques " of Gedoelst, as 

 the latter supposes, since the former not only figures them as 

 being within the six " tlaken," but expressly states that this 

 is the case. The fact that both authors describe and figure 

 six outwardly directed hooks on the lips in addition to what 

 I have termed the jaws (" Fliigel " of v. Linstow, " lames 

 pectinees " of Gredoelst) seems to indicate that they are both 

 referring to the same structure. The presence of the 

 " Spitzen," however, seems doubtful, and one is rather led to 

 believe that v. Linstow's account, in this particular, may be 

 erroneous, possibly as the result of a misinterpretation of the 

 structure of the jaws. The present species apparently 

 possesses neither the " Spitzen " nor the " Haken/' but it 

 occurs to me as not impossible that the incurved terminal 

 teeth of the jaws, when partly, but not wholly, everted, might, 

 by crossing each other, give rise to the appearance of six 

 forwardly-directed points occupying the centre of the oral 

 aperture. 



The writer's thanks are again due to Dr. G. A. K. Marshall, 

 of the Imperial Bureau of Entomology, for the opportunity 

 of examining this material, which was collected by Mr. T. R. 

 Hubback.
