 His description was based oji tlie siipeiHcial cliaiactets oF a small Iray- 

 nieiit of a s[)eeinien collected by Mi'. W. 11. Woostei' at Cooktown, (j)net'ii.s- 

 land : and with ids descrifdion Mae( lillivra v oivt-s his reasons toe allot t ini; 

 tins I'orin to tlii' u'enns ]'] nl h ijris. 



The hoh)type is housed in the colU'ctions of tin- National Mii.sfiirti. 

 Melbourne, l)iit the Anstialian Museum has now aeipiiicd the rcmaindei- 

 of the original specimen from Mr. Woostei . 



This s[)ecies has not atj-ain been refeiced to l)\ t he manv a lit lioi-it ies on 

 the llri/czoii, with the exception of the followino- i-emark l)y Harmei-, 

 which has led me to re-examine it. " I feel doubtful whetlier I'iiil/iijris 

 n-niisleri, Mac(lillivi-ay, is i-ightlv referi'cd to this genus " 



The results of my exannnalion show that " /vr/A //;■/'>• '" irnnslcri ha>, 

 Avith one exception, all the chai'acters entitlirig it id ;\ place in the familv 

 I'luthyiida^, according to Levinsen's diagnosis-': — "The "cirriu are pro- 

 vided with a slightly calcified cryptocyst, and in a laj'ger or smaller part 

 of theii- surface the surrounding covering membrane is kej)t distended by 

 ridge-like or ro(l-sha[)ed pi-ocesses from the cry[)tocyst, which has a 

 nunibei- of superficial rosette-plates. The inlerzocecia I walls have scattered, 

 uinporous i"Osette-plates. A compound opeiculum. No spities and no 

 heterozooecia. There mav l)e endo/ooecial mn-'nt with a projectini:- i-cto- 

 oeciura." 



The exception in the case of this form is in tlie last line of Levinsen's 

 diagnosis, which reads " Free, branched colonies." The small specimen 

 (>btaiiied by Mr. Wooster was found encrusting marine algse, but what 

 t value may be placed on this habit of growth I do not know. MacGilliviay 

 aud others considei' it to be of little inifiortance, and 1 am of the opinion 

 that the encrusting habit of "Enllniri^ '" irnnalrri does not over-iide the 

 structure and give enough reason to place it as yet in a sef)arate ftimilv. 

 It must however be considered as generically distinct fiom the other foiins 

 of the family Euthyridfe, and T projxise the name of Scocntlniris to accom- 

 modate it. From the other- genera of the family its diffeiences will be seen 

 from the key. It is closely allied to F.iillnjris, diffei-ing firstly in having ordy 

 one form of the -/oo'cium with no dimorphism of the operculum; and 

 secondly in the [n-esence and dis[)Osition of the a viciilai-ia.
