larvae of Piniihi>is and related ojenera witli produced snout. It lias been shown above 

 (p. 12f!)for the .Antarctic ^Vo/t'/cy'/x rmifsii tliat there is an extended backward niiiiration 

 of the anus dui-intr the transition from the Pn/mnot/umus stage to the adult fish. 



A laiva of !•_' nun. lias the snout moderately produced. There are 80 myotomes 

 and aliour L'O anal rays. The anus corre.spouds to the twenty-eighth myotonic and the 

 origin of the anal fin to the fifty-fourth (PI. VII, fig. l).

A second larva of 10 mm. has tlie snout more produced than the preceding. 

 There are lie. \crtebrae (52 -f- Gi) and 30 or more anal rays (PI. VII, fig. 2).

In the number of anal rays these examples agree well enough with known .species 

 of Piuitltjilfi, and in the number of myotomes the first agrees with the ^lediterranean 

 .species that I have e.xamiuetl. P(j.ssibl\- /'. JmriiiUs, a .species that I have not .seen, 

 may have the larger number of myotomes found in the second .specimen. 



A tliird ■■ / '/■////iiiothonus" is prolialily generically distinct from the.se; it is a post- 

 laival fisli. 22 iniii. long, evidcin Iv icl.itcil to Parah'pis, which it resembles in tlie 

 structure of the head, but it has only GO myotomes and 11 anal rays. The adipo.se 

 tin is aliovo tlio posterior cud of tlio anal. Dorsal and pelvic fins are undeveloped 

 (PI. Vll, lig. ;]).

This sjiecies is repre.sented in the British Mu.seum collection \\\ iwu examples of 

 G5 and 75 inin. from IMessina. Pellotti's specimens were 75 and 90 iinii., I>rauer's from 

 8 to ."lO linn., llie larncr full L;rii\\n. There is therei'nre reason to suppose that tliis 

 is a small species, and that it assumes the adult ftnni at an eail\' age. 



A larva of 8 mm. that I refer, with some doubt, to this .species has the fin-ravs 

 not yet developc(l, but the form of tlie liead is already as in the adult fish. The 

 pali-hes of pigment on each side of the gut nuuilier only five, instead of eight, but this 

 may be a larval character.
