PLATE IX. 



Forskalia tholoides, n. sp. (p. 244). 



Fig. 6. Apical view (from above) of a complete corm (without nectophores and bracts), 

 preserved in spirit, in a state of extreme contraction. All the nectocalyces 

 and the hydrophyllia are detached. The nectosome exhibits beyond the 

 pneumatophore (p) a multiple series of small tubercles, the basal insertions of 

 the pedicles of the detached nectophores (n). The shortened trunk of the 

 siphosome (a) is vesicular and inflated. The siphosome exhibits the dexiotropic 

 spiral line in which the loose cormidia are arranged. s, The contracted 

 siphons ; t, tentacles ; q, palpons ; r, palpacles ; i, buds. 



Fig. 7. A single loose cormidium, attached to the articulated trunk, with a single 

 siphon and a single tentacle. The long extended pedicle of the siphon 

 (sp) is covered by some denticulate bracts or hydrophyllia (b). From the 

 thickened basal part of the siphon (sb) there arises the long articulated tentacle 

 bearing numerous tentilla, each with a spiral cnidoband (k). The dilated 

 stomach of the siphon (sm) exhibits sixteen longitudinal hepatic ridges (sh), 

 eight longer alternating with eight shorter, sr, Proboscis ; so, mouth. A 

 pediculate gonopalpon (q) bears on its base a thin palpacle (r) and a clus- 

 tered monostylic gonodendron, composed of proximal gynophores (f) and 

 distal androphores (h). qp, Pedicle of the palpon ; behind the gonopalpon is 

 a cyston ; b, bract ; an, nodal constrictions of the trunk, from which all 

 the appendages arise ; ai, internodes ; ac, red central canal of the trunk. 



Fig. 8. A single siphon, highly contracted, so, Mouth ; si, sixteen radial folds of the 

 reflexed proboscis ; sm, stomach with sixteen red hepatic ridges ; sb, four 

 square cnidal plates of the basigaster ; sp, pedicle of the siphon ; t, tentacle 

 (arising in the constriction between pedicle and basigaster). 



Fig. 9. Two cnidal nodes of the mouth-opening ; from each arise two longitudinal 

 glandular ridges, running between the muscles inside the proboscs.
