Two preoculars is unusual, but is not correlated with geo- 

 graphical distribution. U. S. National Museums has one speci- 

 men (No. 51 640) from Semgai Djambajan, Borneo, with one 

 preocular, and one from Sawarna, Bantam, Java, with two. 



Maticora bivirgata (Boie). 



Maticora seems to be the oldest available name for this 

 genus. It was instituted by Gray in 1834 (Iliustr. Indian Zool., 

 vol. 2 (pi. 56, fig. 2j, for M. lineata, but Boulenger rejects it 

 contrary to the International Rules of Zoological Nomenclature 

 art. 25, because it was not accompanied by a definition. For the 

 same inadequate reason he omits even to cite the next two names 

 in time, viz., Fitzinger's Pseudelaps and Gongylocormus 

 of 1843. Pseudelaps is preoccupied by his own Pseudoelaps 

 of 1826, and Gongylocormus must therefore stand as the 

 name of the genus, if for some reason or another Maticora 

 should prove to be unavailable. Maticora seems to stand 

 exactly on the same footing as Calliophis. 



Dr. Thomas Barbour has recently (Proc. New England 

 Zool. Club, vol. 5, Dec. 2, 1914, p. 92) tried to show that Aspis 

 of Laurenti, 1768, should be regarded as the type of the genus 

 having Aspis intestinalis for type, but I cannot agree with him 

 in this view. The type of Aspis, according to the interpreta- 

 tion of Internat. Rules, Art. 30, I, d, by the International Com- 

 mission on Zoological Nomenclature, as expressed in their Opi- 

 nion 16, is clearly Aspis cleopatrae. Laurenti in quoting 

 LucANUs's Aspis as applying to the species Aspis cleopatrae 

 has fixed the latter as the type by tautonymy, whether inter- 

 preting LucANUs correctly or incorrectly. 



It may be well to give the entire synonymy of the genus 

 Maticora as follows:
