160 LIVERPOOL MARINE BIOLOGY COMMITTEE REPORT. 



Spirorbis lucidus, Montagu. 



Spirorbis minutus, Montagu. 



Both mentioned by Carrington. S, lucidus is recorded by 

 Byerley. 



Byerley also mentions S. nautiloides and S, rugosa. I 

 have not been able to discover for what these names are 

 synonyms ; neither specific name occurs in any list of 

 Spirorbes that I am acquainted with. 



Filograna implexa, Berkeley. 

 This species was obtained at low water, between Port 

 St. Mary and Spanish Head, Isle of Man, attached to the 

 roots of Laminaria. It is not recorded by Byerley. 



Protula protensa, Grube. 

 A number of tubes of this form were dredged between 

 Port St. Mary and Spanish Head, Isle of Man, depth, twenty 

 fathoms. No animals were found however, in the tubes, and 

 they have been referred to this species doubtfully. It has 

 not been recorded by Byerley, but was dredged during the 

 " Porcupine " expedition, in five to thirty fathoms, north of ^ 

 the Island of Bona. 



(?). 



Certain tubes of small size forming an irregular mass 

 were dredged at Port Erin, Isle of Man. No inhabitants 

 were found in the tubes. They are leathery, and resemble 

 some Annelid tubes. Dr. Mcintosh, F.K.S., to whom I 

 referred the matter, gives it as his opinion that they are the 

 tubes of a Crustacean, probably a species of Cerapus, but 

 thinks it unsafe to dogmatise. 



Family. — Tomopterid-^. 



Tomopteris onisciformis, Eschscholtz. 



Young specimens of this form were found in the tow-net 



off Port Erin, Isle of Man, on August 7th, 1885. This is 



the common Tomopteris of the British seas, and does not 



call for more detailed notice. It is not recorded by Byerley.
