Some of these names are involved in much obscurity and may remain 

 so, unless the type-specimens be again examined. These names are : 

 M. laevimanus. 

 „ laevis. 

 „ parvimanus. 

 Other names have proved with more or less certainty to be synonyms 

 of already known ones; they are the following: 

 M. affinis = M. depressus. 



„ carinimanus — M. brevis (Herbst nee Hilgendorf). 

 „ compressipes == M. télescopions. 

 „ guêrini = M. pectinipes. 

 „ graeffei = M. convexus. 

 „ inermis = M. convexus. 

 „ laniger = M. latreillei. 

 „ podophthalmus = M. télescopions. 



1) H. Milne-Edwards erroneously cites p. 167 (Ann. Sc. nat. sér. 3, Zool., t. 18.1852. p. 158). 



2) Cleislostoma hirtipes Jacquinot et Lucas (Voyage au pôle sud et dans l'Océanie sur les 

 corvettes „l'Astrolabe" et „la Zélée", Zoologie p. Hombron et Jacquinot, t. 6 p. 68, pi. 6 f. 3 

 et C), said to occur at Samoa, is implicitly referred to Macrophthalmus by G. M. Thompson 

 (Ann. Mag. Nat. Hist. ser. 7, v. 10 p. 462) without however providing more information about 

 his statement. The original specimen of Hombron and Jacquinot has been so badly preserved, 

 that even H. Milne-Edwards in 1852 (1. c. s., p. 161) has been unable to decide the question 

 as to its generic relation.
