side of the base of the older one. I have been unable to ascertain whether a foot-gland is 

 present in the bud or not ; and I cannot give any reliable information with regard to the 

 gonads. 



9. Loxosoma breve n. sp. (PI. I, figs 29 — 31). 



? Loxosoma singulare Waters, 1914, "Mar. Fauna Brit. E. Afr." Proc. Zool. Soa, p. 855 (on 

 Sckizoporella nivea, mostly 011 the opercula). 



131. U. On Sclücoporclla, 131. B. 3 (Type), 131. B. 1 ; and on Cellepora, 131.Q. 2 , Q. 3 . Stat. 164. 

 i°42'.5 S.j i30°47'.5 E. 32 Metres; sand, small stones and shells. 



Size small, total length of the preserved and retracted specimens not exceeding 2 30 ;;.. 

 Of this, the largest specimen found, the calyx m'easures 147 p, in length and the stalk S 3 y. : 

 the calyx is 128 u. broad, and the stalk is as much as 70;;. broad. In other specimens which 

 are better extended the stalk is more elongated, and thinner, measuring 134,'J. in length and 

 only 16 u in breadth. The calyx varies in form according to its degree of contraction, but is 

 oval in those which appear to be best preserved. Several short tactile processes occur on the 

 distal part of the calyx. Number of tentacles 9. Stomach globular. Buds produced in small 

 numbers (not more than one at a time found). Sexes apparently separated, a single individual 

 showing a pair of ovaries, each with a fairly large egg. Stalk of adult terminating in an 

 expanded disc of attachment, without foot-gland. 



I have found this species on slides of a Sckizoporella l ), and a Cellepora, both from 

 the same Station ; several individuals being present on each slide. In the case of the Sckizo- 

 porella^ the attachment is to the outer side of the operculum of the "host" ; and the specimens 

 show distinct tactile processes. The Cellepora preparations had been decalcified ; and it is 

 uncertain how the Loxosoma were attached. These specimens show no tactile processes; but it 

 does not seem necessary to separate them from the others on that account. 



The species appears to be related to L. froglodytes, but is distinguished from it by 

 the want of the conspicuously strong longitudinal muscles of the stalk which are characteristic 

 of that form. 



10. Loxosoma subsessile n. sp. (PI. I, figs 32, 33). 



260. G. On Conescharellina, 260. D. 1 . Stat. 318. 6°36'.sS., H4°S5'.5E. 88 Metres; fine yellowish 

 grey mud. 



Size minute, total length not exceeding about 128 <j. in the preserved material. Calyx 

 not much broader distally than proximally, the well marked lateral lobes of the stomach being 

 accommodated by a corresponding breadth of this part of the calyx, which measures from 90 

 to 1 10 y. in length and 74 to 94 <j. in breadth. Tentacles 8. Buds one on each side. Stalk 

 extremely short, about 26 y. long; much narrower than the calyx, from which it is sharply 

 separated ; without foot-gland or marked disc of attachment.
