Part III. — Eighteenth Annual Report 



Inchkeith on June 8th, 1891, I found amongst other things a single male 

 specimen of the Labidocera referred to. I do not think that this species 

 has been before recorded from the Firth of Forth. 



Cyclopina gracilis, Claus. 



1863. Cyclopina gracilis, Claus, Die fiei-leb. Copep., p. 104, PI. 

 X., figs. 8-15. 



Specimens of this small but distinct species were obtained in a gather- 

 ing of material dredged in the vicinity of Otter Spit, Upper Loch Fyne, 

 during the early part of the year. This gathering contained a large 

 number of comparatively rare copepods, several of which are referred to 

 in the present "Notes." 



Notodelphys prasina, Thorell. 



1859. Notodelphys prasina, Thorell, Bidr. till Kanned. om 

 Krustac. i Ascid., p. 46, PI. V., fig. 7. 

 This copepod has occurred frequently in Ascidians dredged from 

 Tarbert Bank, Loch Fyne, during recent months. N. prasina. has very 

 short caudal furca, and by this character alone it may be readily dis- 

 tinguished from the other species of Notodelphys hitherto recorded from 

 Scotland. Notodelphys allmani, Thorell, is also occasionally found in 

 Clyde Ascidians, but does not seem to be just so common as the species 

 first named. 



Doropygus pulex, Thorell. 



1859. Doropygus pulex, Thorell, op. cit., p. 46, PI. VI., fig. 8. 



A few specimens of this curious species were obtained in Ascidians 

 dredged at Tarbert Bank, Loch Fyne (17-20 fathoms), in October 1899. 

 In this species the caudal furca are "slightly elongate" and "becoming 

 gradually thin, or tapering, towards the distal end " (Canu, Copep. du 

 Boulonn., p. 195). Doropygus pulex appears to be somewhat rare in the 

 Clyde area. 



Doropygus (1) gibber, Thorell. 



1859. Doropygus gibber, Thorell, op. cit., p. 52, PI. VIII.. fig. 11. 

 One or two specimens of a Doropygus, apparently belonging to this 



species, were found in some dredged material from Tarbert Bank, Loch 

 Fyne. Dr. Giesbrecht* considers this to be more nearly related to 

 Noioyterophorus than to Doropygus. 



Doropygus porcicauda, G. S. Brady. 



1878. Doropygus porcicauda, Brady, Mon. Brit. Copep., vol. i., 

 p. 138, PI. XXVII., figs. 1-9 ; PI. XXXIIL, figs. 14-16. 

 Several specimens of this large and apparently distinct species were 

 obtained in the same dredged material as the last. In this species the 

 caudal rami are of considerable length, somewhat divergent and more or 

 less curved. It does not seem to be very uncommon in Loch Fyne 

 Ascidians. 



Enterocola (? ) fulgens, Van Beneden. (PI. XIIL, figs. 21-27.) 



1860. Enterocola fulgens, Van Ben., Bull. Acad. Belg. (2), vol. 

 ix., p. 151, PI. I. 



I have on one or two different occasions found in gatherings of dredged 

 material from the Clyde odd specimens of an Enterocola usually of a
