BEITISn ANNELIDS. 515 



The second section of the Sedentaria contains the families Pherusea 

 with the genera SipJionostomum (2 gp.) : Maldania with Crymene 

 (2 sp.) : Terebellacea with Terehella (10 sp.), a new genus Venusia, 

 for the reception of the Terehella conchilega of Daly ell [it would 

 appear to differ from Terehella, in having all its segments provided 

 with setigerous and uncinated feet, and the tube adherent throughout, 

 horizontal. The branchias are in tufts of simple filaments] and 

 Terehellides (1 sp.) : Amphictenea with Pectinaria (2 sp.), [here we 

 would add the Amphicteis midas, Gosse, described in the Annals of 

 Natural History, 2nd Series, Yol. XVI., under the name of Crosso- 

 stoma midas] ; Hermellacea with Sabellaria (3 sp.), Serpulacea with 

 Sabella (6 sp.) [A new genus, Arippasa, is made for the reception 

 of the Amphitrite infundihulum of Montagu, but this must subside 

 into a synonym oi Myxicola of H. Koch.] Frotula (2 sp.), Serpula. 

 Of this genus following Phillipi we have as subdivisions Serpula 

 (2 sp.), Eupomatus (2 sp.), JPlacostegiis (2 sp.), Vermilia (1 sp.), 

 Pomatoceros (2 sp.), and Spirorbis (17 sp.). 



The last two genera of this family are Fllograna (1 sp.), and Fab- 

 ricia {=Othonia, Johnston). This genus was thoroughly revised by Mr. 

 Gosse, who added to it two species. When we recollect their names 

 (Fairdii and Johnstonii), we wonder how they could have been over- 

 looked. Here, too, for want of knowing where else to place them, must be 

 assigned the two species hippocrepia and cralisy of the very anomalous 

 genus Fhoroiiis of Strethill Wright. The last family given by Dr. 

 Johnston, is called Campontiadae, and contains Campontia eruciformis. 

 This larval form we believe not to be annelidan, but it is hardly within 

 the province of a review to enter into details on such a subject, and 

 besides we are mindful of the rather hard words with which this work 

 closes, " Mr. MacLeay thinks this to be a dipterous larva. Mr. Green 

 thinks he has proved this, but in truth his remarks are very irrele- 

 vant, and deserve no consideration" ! 



There is a genus called Mcea, described for the first time, and an 

 allusion made to details on the 22nd Plate, but our copy has but 

 21 Plates, so we can make rro guess as to its probable affinities. 



We have thus endeavoured, somewhat briefly, to give an account 

 of the leading features of this the last, though by no means the best, 

 of the British Museum Catalogues. Posthumous works are always 

 more or less unfortunate. This one is peculiarly so, for it relates to 

 a portion of Zoology which has lately made, and is now making, great 

 progress, and though published but yesterday, dates some twelve
