196 ANNALS OF SCOTTISH NATURAL HISTORY 



Bay district, and I myself observed it in the estuary of the Clyde ; 

 but though it thus appears to be widely distributed it is only now 

 that I am able to report its occurrence in the Cromarty Firth. 

 Several specimens of this Copepod were obtained in the same 

 gathering with the Erichthonius also now reported for that estuar^. 

 When describing this species in the " Annals and Magazine of Natural 

 History," my son and I referred it to the genus Dermatomyzon, 

 Glaus, but at the same time pointed out certain structural differences 

 between it and that genus. Dr. W. Giesbrecht of Naples, in his 

 revision of the Ascomyzontida (published a few months ago), found it 

 necessary to remove our Copepod to a new genus, and for it adopted 

 the name given above, which is a modified form of the older name.

Sabelliphillus Sarsi, Claparede, in the Clyde. This Copepod, 

 which is remarkable for its curious habit of living on the beautiful 

 feathery plumes that adorn the head of a species of Sabella, one of 

 the marine Annelids, has not yet, so far as I know, been recorded 

 from the Scottish seas, and I have now the privilege of adding this 

 interesting species to the Copepod fauna of Scotland. The specimens 

 I have to record were observed on the plumes of two examples of 

 Sabella captured in Kilbrennan, and on one taken about six to 

 seven miles east of Sanda Island, near the mouth of the Clyde estuary. 

 Sabelliphillus has been known for several years as a member of the 

 marine fauna of Liverpool Bay, and is recorded for that district by 

 Mr. I. C. Thompson, F.L.S. These Copepods are not easily 

 noticed on the plumes of the Sabella, as the two are nearly of the 

 same colour ; they also adhere so firmly to the plumes as not to be 

 readily shaken off even though the plumes are washed in strong 

 spirit, and it is perhaps owing to this that Sabelliphillus has not been 

 more frequently obtained. T. SCOTT, Leith. 



Cytherella serrulata, Brady and Norman, from the mouth of 

 the Clyde. Quite recently I obtained two specimens of this 

 Ostracod in some muddy sand brought up from a depth of about 

 sixty fathoms a few miles south of the island of Sanda at the mouth 

 of the Clyde. Professor G. S. Brady, F.R.S., who kindly examined 

 the specimens, thinks that they certainly belong to the species to 

 which they are ascribed. So far as I know, Cytherella serrulata has 

 not previously been recorded from the British seas ; its occurrence 

 at the mouth of the Clyde estuary is therefore of interest, as, besides 

 being a new record, the distribution of the species is thereby con- 

 siderably extended. T. SCOTT, Leith.
