The uuniher of verteUrae and th(> resenil)lanee to the larval Pilchard {Sai\li7ia 

 pilc/i(trdus) lead me to identify these larvae as Sardinella ji.scudohi-yidiucti. which is the 

 "Western Atlantic representative of the ^fediterranean Allaehe {Sdrdiiicll'i min'/ii, ( 'uv. 

 and \'al.) ; the genera Sardliin and Sardinelhi ai'e very closely related.

Three larval and post-larval fishes may he refern'<l to this .species. 1 count 

 Id dorsal and 16 anal rays and 52 or .58 myotomes. The smallest e.xample, 12nna. 

 loiin-. is more ad\'aiiced than the II "5 mm. Iai-\a of Sdrdimi jiili-liurd lis figured by 

 Cunnino-ham, as the caudal lin is fullv formed and terminal in position, and the anal 

 ravs are a[)peariug. The largest, 18 mm. long, appears to diti'cr from Cunningham's 

 24 nun. .S. /idc/iardii-^ chieHv in details of pigmentation, luit after examination of 

 I'ilcliard larvae from Plymouth, kindly lent by Dr. E. .1. Allen, 1 am doubtful whether 

 there are any constant differences between the larvae of the European species and its 

 re|iresentati\c in the seas of Australia and Xew Zealand.

 nnlikelv that it is cougeneiic with an\' of the specie.s associated under that name. In 

 all prolialiilit \' it belongs to the J'amilv Stomiatidae ; the only other famih' that seems 

 possible is the .Mi'pocephalidae. If this he a Stomiatid it may represent a vimng stage
