\begintext 
 
Several years ago one of us (D.J.M.) determined spectral types for 
some 14,200 IRAS sources. These lay within about 7\deg\ of the 
southern galactic equator, and all had F(12$\mu$m) $\geq$ F(25$\mu$m). 
This work was done using Kodak I-N objective-prism plates taken by him 
some 25 years ago with the Curtis Schmidt at CTIO at a dispersion of 
3400 A/mm at the A band; the spectral classifications were done with 
the support of the NASA Astrophysics Data Program. Although the 
results of this work have been sent to the sponsoring agency 
(NASA/JPL/IPAC), they do not appear to be generally known, so we are 
here presenting the classifications for those named or suspected 
variables for which such data are not given in the GCVS or NSV 
Catalogues. Some of the classifications have already been published by 
Kwok, Volk, and Bidelman (1997), but are repeated here. Also, 
classifications for fifteen of our stars have been published by 
Stephenson (1992), who used near-infrared objective-prism plates of 
approximately twice the dispersion. The agreement of the types is 
excellent. 
 
The resulting spectral types for both the named and the suspected 
variables are listed in Table 1. Stars contained in Stephenson's 
(1984, 1989) catalogues of S-type and carbon stars respectively, are 
identified by their SS and CS numbers, and their spectral types are 
taken from these catalogues except for CS 2795=TU Car, which does not 
appear to be a carbon star. IBVS references are given for those 
variables named since publication of the 4th edition of the GCVS. An 
asterisk following the star name or number indicates that the type of 
variability is open to question in view of the assigned type. 
 
It should be noted here that a large number of our southern suspected 
variables were discovered some 60 years ago by the late Willem J. 
Luyten, whose very substantial contributions to variable-star 
astronomy have not received much recent attention. And, finally, it is 
strongly suggested that the remarks concerning objective-prism 
classification of M-type stars given in IBVS 4230 be carefully noted 
by users of this list.
