Looking again at these because of another thread, I noticed something curious.
In Gulliver's page 169 he described the applied animals on the bowl id'd as Webb, top of the page, as 'lizards' and indeed they have long tails, the fishy open mouth face and it seems three curvy spiny rigaree applications on their back, but they also have 'arms' on their front feet extending to their 'hands'. On the one overleaf in the book page 170 that has a straight rim with the body looking like it has 'stripes' of blue and silver foil and a ruby interior to the bowl, he also described them as 'lizards' however whilst they have tails and a spiny back (it looks different to the Webb id'd one), they don't seem to have 'arms' before the 'hands', it looks like they just have the 'hands' although it is difficult to see exactly.
Neither seem to have applied red eyes or enamelled mouths (just adding this for future reference as it seems some of these fishy bowls have red eyes and enamelled mouths)
Sorry,it's not adding anything but just an observation.
Edited to add
oh, I didn't realise but this bowl seems to have been formally identified as Stevens and Williams in Manley's book of Decorative Victorian Glass page 61
