The map numbers and titles listed in Chris's question below are correct.  I-2588,
"Sidescan sonar image, surficial geologic interpretation, and bathymetry of the
Long Island Sound sea floor off Haammonasset Beach State Park Connecticut" was
published in 1997.  This year the map titled "Geologic map of the western Ophir
Planum region of Mars" was published using the same number.  To correct the error
without a costly reprint, this map was renumbered I-2588-M (for Mars) by hand.
I -2588 is not intended to be a series with additional maps published as
I-2588-A, etc.

I am confused about the numbering of a couple of USGS I-series maps.

In August of 1997, we received I-2588--"Sidescan sonar image, surficial
geologic interpretation, and bathymetry of the Long Island Sound sea floor
off Haammonasset Beach State Park Connecticut."
I numbering seems correct because I-2589 is a similar map.

But this July we received "Geologic map of the western Ophir Planum region
(MTM-10067) of Mars."  The envelope was numbered "I-2588."  However,
someone at USGS (?) had written, in pen, an "M" after the number.  The
number makes no sense when contrasting it with the previous "I-2588."

I find no other "Ophir Planum" maps in the I-series.

Is the number "I-2588-M" incorrect?  If so, what should the correct number
be?

Thanks in advance.
