batur. These appear to differ slightly from the Madras form 

 in being a little more granular, in having a slightly longer 

 tail, and in having the anterior margin of the cephalothorax 

 a little more deeply excised. 



This species also presents strong points of resemblance 

 with H. diremptuSj Karsch — the only species of the genus 

 known from Africa — but, according to the description, the 

 cephalothorax of direnvptus is a little longer than the " hand- 

 back," whereas in Iceviceps it is always shorter; moreover, 

 the movable finger of diremptus beai-s near the middle of its 

 inner surface a large lobe and the fingers are widely separated 

 at the base when closed (in Icevicepis they are in contact 

 throughout their length). 



ClIILOPODA. 



Only a few species of this group were obtained, yet more 

 than half of them prove to be new. Of these one is a species 

 of Himantarium and the others are species of Otostigma. 

 It seems at first a surprising fact that out of the four species 

 of Otostigma in the collection all should be new to science ; 

 but it is not a matter for wonder in the face of the circum- 

 stance that, although this genus is richer in species in the 

 Oriental Region than any other (with the exception perhaps 

 of Scolopendra) , yet until now only one species, and that a 

 widely distributed one, has been recorded from India proper ! 



In fact, the knowledge that we possess of Indian Myrio- 

 poda — and the same almost may be said with respect to 

 Spiders and Scorpions — is ridiculously scanty considering the 

 length of time that the country has been occupied by the 

 English. Judging by analogy, these animals must be 

 exceedingly abundant, and an enormous number of new forms 

 could doubtless be collected by anyone who would but take 

 the trouble to look for them. 



Scutigera longicornis (Fabr.). 



A very widely ranging species. Common in India and 

 Burma, and extending through Sumatra and Borneo. 



Genus Rhysida. 



Rhysida, Wood, Journ. Ac. Sci. Philad. v. p. 40 (1863). 



This name was put forward by Dr. Wood to take the 

 place of Br and do stoma of Newport, Branch iostoma having 

 been previously applied by Costa to the genus which is com- 

 monly known as Amphioxus. But Dr. Wood's proposal has
