I find that one extreme term in tlie series of modifications to 

 which the Mammalian coracoid is susceptible is reached in the 

 Edentata (Tamandua, fig. If, and Tatusia fig. 1 y, p. 589), viz. 

 the con'plete exclusion of the scapula from the fully-formed glenoid 

 facet, by the fusion and joint extension of the metacoracoid and 

 scapular epiphyses (Co" and ep., figs. 1 /, y, h). I have only observed 

 this peculiarity in Aides maryinatus and Lutra vuhjaris among the 

 higher forms which I have examined. Its independent assumption 

 in them appears, by analogy, to lend additional support to the 

 belief that the overgrowth of the epicoracoid and scapula to enclose 

 the so-called coraco-scapular foramen (/o., figs. 1 cl, e, li) is a 

 secondary and independently acquired character. 



8. On some new Species of the Land-Molluscan Genus 

 Alycaus from the Khasi and Naga Hill Country^ 

 Assam, Munipur, and the Ruby Mine District, Upper 

 Burmah ; and on one Species from the Nicobars. 

 By Lt.-Col. H. H. Godwin-Austen, F.R.S., F.Z.S., &c. 



[Received June 20, 1893.] 



The present paper is to a great extent a continuation of one 1 

 read before the Society last year * describing the DipJonimatincp. 

 from the Assam Hill Ranges which Mr. Doherty's excellent 

 collecting had accumulated. 



The Alycd-i now described include those which Mr. Doherty 

 obtained in North Burmah, oue species which I discovered myself in 

 Munipur, and another of which examples have lately been sent to 

 me by Colonel Beddome, who receiAed them from Mr. Muspratt, 

 au officer now stationed in the Naga Hill Country. I also take 

 this opportunity to describe a new species of the same genus of 

 which au example, found by INIr. Bushy at the Nicobars, was in 

 Dr. Hungerford's fine collection. 



In 1871 (J. A. 8. B. 1871, pi. iv. fig. 3) 1 figured an Alycreus 

 from the Naga Hills as "^. inyrami, var." A comparison of it 

 with typical specimens of A. inyrami now shows me that it is quite 

 distinct, and 1 therefore name it A. distinctus. I referred to the 

 same species again in 1874 (J. A. S. B. 1874, p. 150) and gave 

 the many localities where 1 had subsequently obtained it. 1 liave 

 lately received from Col. Beddome, also from the Naga Hills,
