Mackerel Sky versus Carp Sky

I'm stealing an argument from this book regarding what is called the Mackerel Sky and what he wants to call Carp Sky. To start, the two fish (pictures from Wikipedia):

Mackerel

and Carp

Note the striations of the mackerel versus the scaly pattern on the carp. Now, the clouds. The first two were taken by myself, and the last one by my mother up in Rochester.



The clouds I saw are much more similar to a carp than a mackerel, and therefore are altocumulous stratiformis perlucidus (middle-height puffy clouds that extend over a large area with gaps inbetween), while the clouds that my mother sent look more like the mackerel. However, they are still middle-height clouds. The size of the individual cloudlets are about the width of a finger (which would indicate altocumulous), rather than the size of grains of salt (which would indicate cirrocumulus). So I'd still call the Rochester clouds Carp Sky, but with more of an undulating pattern than the ones over Ithaca.

I will keep my eye out for a better example of a Mackerel Sky.
