Should be intended as well. If you try to set a dtype from a list, it has to 
follow the format of a description as specified in:

http://numpy.scipy.org/array_interface.shtml

for example:

In [67]: dtype([('f1', int16)])
Out[67]: dtype([('f1', '<i2')])

In [68]: dtype([('f1', int16, (2,2))])
Out[68]: dtype([('f1', '<i2', (2, 2))])

In [69]: dtype([('f1', int16, (2,2)), ('f3', int32)])
Out[69]: dtype([('f1', '<i2', (2, 2)), ('f3', '<i4')])

Cheers,
