ever, sent me a small representation from that little visited 

 locality. To him my very hearty thanks are due. 



SpJiaerodactyhis sputator Sparrman 



To secure this species, so long in doubt, was the principai 

 object of Peters' quest. He gathered an enormous series. 

 This shows that the types of Sparrman now in Stockholm did, 

 beyond doubt, come from this island and that the species is 

 essentially as I placed it in my recent revision (^lem. M. C. Z., 

 47, 192 1, p. 266). It is one of the dichromatic forms, as are 

 so many of the large-scaled species — and perhaps others as 

 yet little known. The types are females evidently. The males 

 are much smaller than the females, uniform greyish brown 

 through life, or at the most with a few fine scattered dots 

 usually on the head. The females are large, bulky and with 

 a great variety of broken bands, blotches and spots of vary- 

 ing size. 



By the kindness of my old friend and companion, Dr. 

 Carlos de la Torre, rector of the University of Havana, I am 

 permitted to record a very surprising observation, based upon 

 field and laboratory studies carried on by Professor de la 

 Torre and his correspondent, Senor Cabrera. Lizard eggs of 

 known ancestry having been secured and hatched show that 

 Spliacrodactylus clegans is nothing more nor less than the 

 very young of Spliacrodactylus cinereus, while extensive field 

 collecting at various seasons of the year has also shown that 

 during growth the individuals pass through a stage which has 

 given rise to the name SpJuierodactylus intermedins. There 

 is a considerable change of habitus as well as coloration dur- 

 ing this course of development. The new synonymy should, 

 therefore, stand thus:
