In the abdomen NB 1-1 gives rise to a cluster comprising 4-6 ipsilaterally projecting interneurons and no motoneurons; in addition the abdominal clone comprises 3 subperineural glial cells (the two dorsal A- and B-SPG and the ventral LV-SPG; Klämbt and Goodman, 1991; Ito et al., 1995). Thus, NB 1-1 represents a segment-specific neuroglioblast. With the exception of the aCC/pCC neurons and glial cells, the clone is located in the ventrolateral cortex. The aCC motoneuron innervates dorsal muscles (Sink and Whitington, 1991; for description of muscle pattern see Crossley, 1978, and Bate, 1993) . The thoracic 1-1Ms axons terminate among ventrolateral muscles without a detectable endplate. The pCC interneuron forms an ipsilateral anterior projection.
