35. " Caligus minutus, Otto, Nordm.;" Edw. vol. iii. p. 450, and 



Reg. Anim. pi. 77. f. 2. 



I obtained a specimen off a holibut in Belfast market in February 

 1837. It differs very little — hardly in species — from C. hippoglossi, 

 Kroyer, Tidssk. bindi. p. 625. pi. 6. f. 3 (1st series). 



M. Edwards notes the species as found on the coast of Bretagne 

 in the branchial cavity of the "Bars" [Basse. Labrax lupus, Cuv.]. 



36. Caligus curtus, Kroyer, Tidssk. 2 bind, tab. 104. pi. 1. f.l m. 

 On Raia maculata taken in Belfast bay, April 1839, W. T. See 



M. Edwards, ' Hist. Crust.' vol. iii. p. 451, for remarks on C. curtus-, 

 Mull. &c. 



37. Caligus diaphanus, Nordm., Kroyer, bind ii. pi. 1. f. 3. (Re- 



ference to pi. 1 at p. 104.) 



Nordmann obtained this species off Trigla hirundo. I have pro- 

 cured it not only on that fish but on the following, purchased in 

 Belfast market: — Trigla pint, Pagellus centrodontus, Scomber scorn- 

 brus, Caranx trachurus, Merlangus carbonarius, Merlucius vulgaris, 

 Lota molva, Platessa vulgaris and Pleuronectes maximus. The speci- 

 mens were taken in March, August, October and December (1837). 



M. Edwards (vol. iii. p. 452) refers only to the above-cited authors 

 for this species. 



38. Caligus pectoralis, Kroyer, Tidssk. bind i. p. 628. pi. 6. f. 4. 



M. Edwards notices this as found on turbot, plaice and other flat- 

 fishes (vol. iii. p. 454). I have procured it on Platessa flesus, P. li- 

 manda, Solea vulgaris, Scomber scombrus, Zeus faber and Conger vul- 

 garis, brought to Belfast market in March 1837 : they adhered to all 

 the exposed parts of the body of the various fishes, and not to the 

 gills, &c.
