10 Mr. C. T. Regan on the British Fishes 
56. Alosa finta algertensis, subsp. n. 
Depth of body 3 in the length, length of head 4, 29 gill- 
rakers on lower part of anterior arch. Dorsal 18. Anal 22. 
58 scales in a longitudinal, 20 in a transverse series. Scutes 
21+165. 
A single specimen, 300 mm. in total length, from Algeria 
(Playfair). A young fish of 170 mm. from Mogadore has 
the depth 32 in the length and 24 gill-rakers on the lower 
part of the anterior arch ; it seems more likely that it pertains 
to this race than to the typical A. finta. 
5¢. Alosa finta nilotica, Geoff. 
Clupea nilotica, I. Geoffr. Descr. Egypte Poiss. p. 286, pl. x. fig. 1 
(1827). 
Clupea finta, Bouleng. Cat. Afr. Freshwater Fish. i. p. 154, fig. 123 
(1909). 
Depth of body 3 to 3? in the length, length of head 32 to 
42, 20 to 23 gill-rakers on lower part of anterior arch. 
Dorsal 17 to 20. Anal 20 to 24. 55 to 63 scales in a longi- 
tudinal, 18 to 20 in a transverse series. Scutes 20 to 24+ 
14 to 15. 
Mediterranean. 
Several examples, up to 420 mm. in total length, from 
Egypt, Constantinople, and the Adriatic. From Moreau’s 
enumeration of the gill-rakers (Poiss. de France, iii. p. 456), 
it seems that this form occurs also on the Mediterranean 
coast of France. The two examples from Algeria listed by 
Boulenger are not of this subspecies—one has 29, the other 45 
gill-rakers on the lower part of the anterior arch. 
5d. Alosa finta lacustris. 
Alosa vulgaris, Pavesi, Pesci e Pesca Ticino, p. 54 (1872). 
Alosa finta, var. lacustris, Fatio, Faune Vert. Suisse, v. p. 51 (1890). 
Depth of body 4 to 44 in the length, length of head 4. 
30 to 34 gill-rakers on lower part of anterior arch. 63 to 70 
scales (? including some on base of caudal) in a longitudinal 
and 17 to 20 in a transverse series. Ventral scutes 38 to 41. 
Vertebre 59. 
Lakes Maggiore, Como, and Lugano. 
Length 160-300 mm. or more. 
5e, Alosa finta gracilis, subsp. n. 
Depth of body 42 in the length, length of head 4. 36 gill- 
rakers on lower part of anterior arch. Dorsal 17 to 19.
