46 Treubia Vol. Ill, l. 



shifting of the anus, noted in the older of the larvae studied, continues, 

 causing the anus which we have already seen moving forward from the 

 57th or 58th mybtome to the 52th myotome finally to lie under the 43th, 

 or 44th vertebra. 



For the number of vertebrae I found in four specimens: 



44 + 29 = 73. 



43 + 30 = 73, 



44 + 30 = 74. 

 43 + 29 = 72. 



Summing up we may say: 



The eggs of Chirocentnis dor ab resemble those of the clupeids in that 

 the yolk is segmented. They are distinguished by the presence of a number 

 of small oil-globules and by the reticulate design of the egg-membrane. 

 The larval development. wholly conforms to the clupeid type.
