All D shell connectors are not size B, only those with 25 pins - the
proper designation being DB-25. The 15 pin versions are DA-15 and
DE-15 (the latter being the three row version). The 37 and 50 pin
versions are DC-37 and DD-50 respectively.
Size-wise, besides the "standard" D-subminiature connectors are HD,
micro, and nano variants.
<http://en.wikipedia.org/wiki/D-subminiature> has an excellent
rundown on the various flavors (flavours) and variants of these
connectors.

So, what does one call the 19-pin two-row D-sub connector used on the
Atari 520ST/1040ST boxes for the hard disk connector (Apple used them
for an external drive connector on the Mac also)?
Yeah, I know--"19 pin two-row D-sub".

I've seen them called DF19' (and 'DG23' for the 23 pin connector used,
for example, on the Amiga video port), but I suspect that's unofficial

I'll agree with that.

DD78 -- 4 rows of pins. Some IBM gear I have uses it for connection to a
Bus & Tag "breakout" cable.

I have equipment at home with a DB44 (external IDE connection for
CD-ROM on a Planar-brand 486 in an LCD-based wall-mount computer) and
a DA26 (Cisco AGS+ router).
I've never seen a high-density D-shell either.

There is a DD78 (relatively common on multiport serial interfaces and
also used on IBM parallel channels), and even a DD100, which I've
only ever seen once (on the IBM microchannel 8-port EIA-232 ARTIC
Portmaster Adapter/A)

New subject: Digi-Comp 1 is back (from 1960s)
The Digi-Comp1 3 bit "mechanical" computer is being re-issued in a $49
(USD) kit. This has to be one of the coolest computer learning tools ever.
Check out the link:
http://www.retrothing.com/2006/02/build_your_own_.html
You could always build your own ... But for $49 it beats the hell out of the
40 year old kits on E-pay that sell for more !!
Best regards, Steven
