52 LIVERPOOL MARINE BIOLOGY COMMITTEE REPORT. 



found a single example of the more exclusively marine form 

 Cfoliacea, Philippi. This is a form which should be sought 

 for in subsequent examination of dredged material. 



Dendrophrya spp., Strethill Wright.* 



" Test adherent, consisting of a sessile chamber with 

 erect or spreading arms. Arms tubular, erect, often 

 branching, with apertures at the distal ends. Walls 

 chitinous, coated with mud." — Brady. Dendrophrya is 

 quite common along the N. Wales coast, especially in low 

 water pools near the Little Ormes Head. Its branching, 

 interlacing, muddy tubes frequently cover the whole surface 

 of the polypidoms of Polyzoa and Hydrozoa. I have found 

 both host and Rhizopod living and active together on many 

 occasions, and I do not doubt the genus is equally common 

 in similar localities, i.e,, muddy places, round the coast 

 generally. And yet, as Mr. Brady observes, *' the genus 

 appears to have remained entirely unnoticed by Bhizo- 

 podists." The description and figures given in the Chal- 

 lenger Report are from specimens obtained from the West 

 Coast of Scotland, by Mr. D. Robertson of Glasgow, who 

 sought specially for them at the request of Mr. Brady. 

 Wright describes the "sarcode of the organism as diflfering 

 from that of other Rhizopods, in being filled with delicate 

 short fibres instead of the usual molecular matter, and 

 containing both within the shell and tubes the highly 

 refractive bodies I have mentioned in a former paper as 

 ova."t The occurrence of the genus in some quantity in a 

 locality which is the annual health resort of many of our 

 local students of Natural History, offers special inducements
