of band i, but reversed to the left and involving only 2 scutes. 

 This is another case of reduplication in anterior and posterior 

 parts of the banded region, but there is also in this case a sym- 

 metric reversal. 



Fetus I. has in band 9 in position 8 from the right a double 

 scute. This is evidently the genetic equivalent of the two double 

 scutes in band 8 of the mother, but the symmetry is reversed. 



Fetus II. has in band 8, 8 scutes from the right, a double scute 

 which is doubtless the reversal or mirror-image of that in its 

 twin partner, fetus I. 



Set K. 34, tf (Table Bi). 



In this set the genetic relations are quite obscure. 



The mother has in band I, beginning after 3 single scutes on 

 the left a doubling of the rest of the band. 



Fetus I. has in position 10 from the left margin of band 6 a 

 double scute. 



Fetus IV. has in position 5 to the right of the middle of band 

 3 a double scute. 



Set K. 16 cf (Table Bi}. 



The mother shows a right lateral and a median doubling of 

 band i. 



Fetus II. has one double scute in band i, situated in the middle 

 of the left side of band i, another case of centre-lateral sym- 

 metry reversal. 



Set K. 35, 9 (Table Bi}. 



The mother has a rather unusual anomaly in the form of two 

 "'split" scutes separated by several single scutes, occurring in 

 band I, in places 10 and 15 respectively from the left-hand 

 margin. In band 2 we find the bilateral equivalent of these 

 -elements in the form of one double scute situated in position 13 

 from the right. 



Fetus I. is the only one of the offspring to inherit the maternal 

 anomaly. There is in band i a double scute situated 13 places 

 from the left in the reverse position of that seen in band 2 of 

 the mother. The genetic relations here are quite clear, but 

 why should only one out of four offspring show an inherited 

 character?
