 (Plates XXIV. & XXV.) 

 No species of Myriopoda have hitherto, so far as I am aware, 

 been recorded from, the Mergui Archipelago, but considering the 

 proximity of this group of islands to the mainland of the Malay 

 Peninsula, it is not surprising that most of the large and con- 

 spicuous forms obtained are referable to species which have been 

 from time to time described from various parts of the Oriental 

 Begion. 



Those that are new are, with one exception, small and incon- 

 spicuous individuals, which would in all probability have been 

 overlooked or ignored by any but a scientific collector. 



Very little need here be said about the Chilopoda. One specimen 

 only, a species of Himantarium, is new. The rest are well known 

 Oriental forms. With regard to these I have deemed it sufficient 

 to give references to the excellent descriptive papers of Dr. 

 Meinert and Dr. Haase. 



The Diplopoda are in some respects of greater interest, and 

 have been treated in consequence at greater length. Knowing 

 from experience the immense difficulties to be encountered in 

 the endeavour to identify merely from descriptions specie3 of 

 this group, I have thought it advisable to describe and figure, 

 whether old or new, every specimen occurring n the collection. 

 Fortunately, in most cases, individuals of each sex were taken ; 

 it has been possible, therefore, to examine the male copulatory 

 apparatus, and to point out the specific distinctions presented by 

 this organ. I have described as new one species of Glomeris^ 

 two of Paradesmus, two of Spirostrejptus, and one of Spirobolus. 



It is with great pleasure that I take this opportunity of ex- 

 pressing my obligations to Dr. Meinert and to Dr. Karsch for 

 kindly comparing most of the specimens here enumerated with 

 the types of species preserved in the Museums at Copenhagen 

 and at Berlin, to which I had no access. 



"With the object of assisting fellow-workers, by affording them 

 some means of ascertaining what has already been done with 

 regard to this group of animals in the East, I have added at the
