Between the n''' and 12'h siphon the stem is devoid of any appendages. But as this interval is 

 longer than can be the case in a normal living Rhizophysa we suppose either that the stem 

 has considerably stretched or that appendages are lost.

The specimens of Rhizophysa Eysenhardti do not differ from R. filiforinis as far as 



their mode of preservation is concerned. We also found in these specimens that verj- often the 



stem is twisted in such a wa)- as to make it exceedingly difficult to disentangle it. The stem 



often breaks off and the different parts have to be reconstructed, the size of the cronodendra 



being the only guides. The length of the different stems in the specimens measure: 



Cat. 96 18 cm. 



Cat. 19 20 cm. 



Cat. 20 A 50 cm. 



Cat. 17B 55 cm. 



Cat. 14 A 136 cm. 



Cat. 17 A 140 cm. 



We only give sketches of Cat. 20 A. and Cat. 14 A. as they are the most important. 

 Cat. 96 resembles absolutely Rhizophysa filiformis Cat. 15 A. but for the shape of the tentilla. 

 These resemble exactly the tentilla Huxley 59 describes and figures for a Rhizophysid which he 

 vvrongly called Rhizophysa filiformis. There is, however, no reason not to identify this specimen 

 with Gegenbaur's Rhizophysa Eysenhardtii. It is a remarkable coincidence that Huxley also 

 found his specimen in the Indian Ocean. H.\eckel's Nectophysa Wyvillei, probablv also a true 

 Rhizophysa Eysenhardti was caught near the Canary Islands (Lanzerote). Cat. 19 does not 

 differ actually from Cat. 96. 



Cat. 20 A. (PI. XX, fig. 147) is in so far interesting as it is a very complete specimen. 



Its pneumatophore surpasses in size even the measures given by Chun (97a p. 79). He 

 finds a Rhizophysa filiforinis whose pneumatophore has a length of 12 mm., a breadth of 

 1 1 mm. He writes that these are dimensions which have only been surpassed by Bathyphysa 

 Grimaldii, whose pneumatophore in the largest specimen, as Bedot tells us 93, measures 17 mm. 



Our specimen has a pneumatophore of 18 mm. in length, and 11 mm. in breadth. We
